Oracle Linux 上安裝JDK(Java Development Kit) & 註冊 JBoss EAP 6.x standalone 為 Service

之前的 JBoss 的 JBoss EAP6 Domain Mode Setup 與 JBoss EAP6.x Standalone Mode Cluster Configuration 都在 Windows 平台上作測試，現在起將拋棄微軟擁抱 Linux，因為後續的資料庫也是使用 Oracle DataBase，因此 Linux 平台選擇 Oracle Linux，大致的安裝過程可以查看 Oracle Linux Install Using LVM 。

安裝檔下載：

1. Oracle Linux 的來源可從下面取得：

https://edelivery.oracle.com/linux

2. 下載JDK：

Oracle的官網可以下載到最新的JDK版本，官網網址如下：http://www.oracle.com/technetwork/java/javase/downloads/index.html

所有的版本：http://www.oracle.com/technetwork/java/archive-139210.html

3. 指令：

會使用到 rpm 或 yum 的安裝移除令，可以參考 yum 基本介紹和參數說明

安裝 JDK 方法一開始(建議以此方法為主)：

1. 查詢 Oracle Linux 預設的 openJDK ： OracleLinux7.1_x86_64 所搭配的 Java 是 openJDK ，用 rpm -qa | grep java 查詢後將它移除

[root@localhost ~]# rpm -qa | grep java
java-1.7.0-openjdk-1.7.0.75-2.5.4.2.0.1.el7_0.x86_64
python-javapackages-3.4.1-6.el7_0.noarch
javapackages-tools-3.4.1-6.el7_0.noarch
tzdata-java-2015a-1.el7.noarch
java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.0.1.el7_0.x86_64

2. 移除 openJDK ，可以使用 yum remove java* 或者 rpm -e package_name 指令

[root@localhost ~]# yum remove java*

Complete!

3. 使用 rpm 指令安裝 jdk-8u45-linux-x64.rpm

[root@localhost tmp]# rpm -ivh jdk-8u45-linux-x64.rpm
正在準備…                       ################################# [100%]

[root@localhost tmp]# javac -version
javac 1.8.0_45

利用 rpm 安裝完的 JDK，根目錄會在　/usr/java/jdk1.8.0_45

[root@localhost java]# pwd
/usr/java
[root@localhost java]# ls -l
總計 4
lrwxrwxrwx. 1 root root 16 8月 17 16:36 default -> /usr/java/latest

lrwxrwxrwx. 1 root root 21 8月 17 16:36 latest -> /usr/java/jdk1.8.0_45

4. 編輯「/etc/profile」檔案。這個profile檔案裡寫的指令在系統開機時會自動執行。

使用「export」指令來設定Java相關的系統環境變數。要設定的變數有「JAVA_HOME」、「JRE_HOME」、「PATH」、「CLASSPATH」。「JAVA_HOME」為JDK的目錄，就是剛剛複製到「/usr/lib」目錄中的JDK目錄，「JRE_HOME」為 JRE(Java Runtime Environment)的目錄，JDK有包含JRE，位置就在JDK目錄下的「jre」目錄。「PATH」變數為系統尋找指令(檔案)的路徑，將「JAVA_HOME」變數和「JRE_HOME」變數加進原先的「PATH」變數前。「CLASSPATH」變數為Java尋找Java程式所使用到的 Class路徑，路徑可以是目錄也可以是.jar檔案，將目前的目錄「.」和「$JAVA_HOME/lib」與「$JAVA_HOME/jre /lib」加進變數中吧！

範例如下：

export JAVA_HOME=/usr/java/jdk1.8.0_45
export JRE_HOME=/usr/java/jdk1.8.0_45/jre
export ANT_HOME=/opt/apache-ant-1.7.0
export JBOSS_HOME=/opt/jboss-eap-6.3

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH:$ANT_HOME/bin
export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JRE_HOME/lib

重新關機後，就可以生效。

安裝 JDK 方法二開始(特殊需求時使用)：

Step 01：將 jdk-8u45-linux-x64.tar.gz 解壓縮在 /opt/jdk1.8.0_45

Step 02：編輯「/etc/profile」檔案。這個profile檔案裡寫的指令在系統開機時會自動執行。

export ANT_HOME=/opt/apache-ant-1.7.0
export JAVA_HOME=/opt/jdk1.8.0_45_x64
export JRE_HOME=/opt/jdk1.8.0_45_x64/jre
export JBOSS_HOME=/opt/jboss-eap-6.3

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH:$ANT_HOME/bin
export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JRE_HOME/lib

重新關機後，就可以生效。

安裝 JBoss EAP 開始：

1. 到 https://access.redhat.com/downloads/ 下載 jboss-eap-6.3 的 zip 檔，並解壓縮放在 /opt/jboss-eap-6.3

2. 執行 /opt/jboss-eap-6.3/bin/add-user.sh 增加管理 JBoss EAP Server 的帳號

3. 執行 /opt/jboss-eap-6.3/bin/standalone.sh 就可以手動啟動 JBoss EAP , 並可以在本機輸入網址 http://localhost:9990/console/ 進入管理.

在 Oracle Linux 上建立 JBoss EAP 的 Service

1. 編輯 $JBOSS_HOME/bin/init.d/jboss-as.conf ，檔案內容至要少有 JBOSS_HOME & JBOSS_USER 這兩個變數的設定。

範例如下：

# General configuration for the init.d scripts,
# not necessarily for JBoss AS itself.

# The username who should own the process.
#
JBOSS_USER=root
JBOSS_HOME=/opt/jboss-eap-6.3

2. 將 $JBOSS_HOME/bin/init.d/jboss-as.conf 複制到 /etc/jboss-as 目錄，與 $JBOSS_HOME/bin/init.d/jboss-as-standalone.sh 複制到 /etc/init.d

Copy the modified configuration file to the /etc/jboss-as directory.

[user@host init.d]$ sudo mkdir /etc/jboss-as

[user@host init.d]$ sudo cp $JBOSS_HOME/bin/init.d/jboss-as.conf /etc/jboss-as/

Copy the start-up script to the /etc/init.d directory.

[user@host init.d]$ sudo cp $JBOSS_HOME/bin/init.d/jboss-as-standalone.sh /etc/init.d

3. 修改 /etc/init.d/jboss-as-standalone.sh 內容，如紅色標注部份，因為 JAVA_HOME 已在前面有設定了, 所以不用再作判斷。

#!/bin/sh
#
# JBoss standalone control script
#
# chkconfig: - 80 20
# description: JBoss AS Standalone
# processname: standalone
# pidfile: /var/run/jboss-as/jboss-as-standalone.pid
# config: /etc/jboss-as/jboss-as.conf

# Source function library.
. /etc/init.d/functions

# Load Java configuration.
#[ -r /etc/java/java.conf ] && . /etc/java/java.conf
#export JAVA_HOME

# Load JBoss AS init.d configuration.
if [ -z "$JBOSS_CONF" ]; then
JBOSS_CONF="/etc/jboss-as/jboss-as.conf"
fi

[ -r "$JBOSS_CONF" ] && . "${JBOSS_CONF}"

# Set defaults.

if [ -z "$JBOSS_HOME" ]; then
JBOSS_HOME=/opt/jboss-eap-6.3
fi
export JBOSS_HOME

.

4. 註冊 JBoss 為 Service

[user@host init.d]$ sudo chkconfig --add jboss-as-standalone.sh

5. 執行指令 setup 檢查 JBoss EAP 的服務是否有設為自動啟動( [*] jboss-as-standalone.sh)，若沒有則按空白鍵作設定。這樣啟 OS 時，JBoss EAP 就會自動帶啟。

[root@localhost ~]# setup

linux_setup

setup_jboss_service

4. 手動啟動/停止/重啟 JBoss

[root@localhost ~]# sudo service jboss-as-standalone start [stop] [restart] [status]

[root@localhost ~]# sudo service jboss-as-standalone
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status)

Windows Server 2003 為 VMware 的 guset ，若要擴展 disk 空間，可以使用 diskpart 的指令來作。作業大致如下：

Step 01：Add Additional Space to the Virtual Hard Drive

- Using the vSphere Client, connect to vCenter server or your host.
- Once connected, select your Virtual Machine from the Hosts & Clusters or VMs & Templates view.
- Click "Edit Settings"
- Select your Virtual Disk, and increase the Provisioned Space.
- Click OK

Step 02：Extend the Windows Server Volume

- Access your Server (either Open Console from the vSphere Client or RDP)
- Open a Command Prompt
- Use the following commands from the Microsoft KB 325590

實作如下：

C:\>diskpart

Microsoft DiskPart 5.2.3790.3959 Copyright (C) 1999-2001 Microsoft Corporation.
On computer:

DISKPART> list volume

磁碟區 ### Ltr 標籤     Fs     類型        大小     狀態     資訊
---------- --- -----------   ----- ---------- ------- --------- --------
磁碟區 0     E                  NTFS   簡單           400 GB 狀況良好

磁碟區 1     Y   新增磁碟區 NTFS   磁碟分割       10 GB 狀況良好

磁碟區 2     C                    NTFS   磁碟分割      30 GB 狀況良好

磁碟區 3     D   CRMSVOL_EN   CDFS   DVD-ROM      594 MB 狀況良好

DISKPART> select volume=1

磁碟區 1 是所選擇的磁碟區。

DISKPART> extend

DiskPart 成功地延伸了磁碟區。

DISKPART>exit

PS：磁碟的型態是基本或動態(如下圖)所擴展出來的空間會有不同，但在前端看到的是一樣的。

VMware Esxi:Disk Consolidation Needed - Unable to access file since it is locked

環境是 VM vSphere Esxi 5.x Standard

在 vCenter 中看到，系統出現 "Virtual machine disks consolidation is needed" ，代表 vdk 檔要作 consolidation 。但在執行的過程中發生 Unable to access file since it is locked 的錯誤訊息。

解決的方法：

Step 01：用 SSH 連到主機端, 查看 vmware.log ，看是那一個檔被 Lock 。
# vi vmware.log

2015-06-02T09:52:50.430Z| vmx| I120: [msg.nvram.wback1] Could not create '/vmfs/volumes/50eaa6a3-bd303b99-7190-3440b5c68358/PLM/PLM.nvram': Failed to lock the file 2015-06-02T09:52:50.430Z| vmx| I120: ---------------------------------------- 2015-06-02T09:52:50.454Z| vmx| W110: NVRAMMGR: Failed to create default NVRAM file (PLM.nvram)

Step 02：使用指令 mkfstools -D 查看那台主機 lock ,
# vmkfstools -D PLM.nvram

Lock [type 10c00001 offset 107448320 v 16455, hb offset 3289088
gen 51, mode 1, owner 5480349c-42ed69c6-xxxx-3440b5ca5488 mtime 1279740
num 0 gblnum 0 gblgen 0 gblbrk 0]
Addr <4 105="" 169="">, gen 16414, links 1, type reg, flags 0, uid 0, gid 0, mode 600
len 8684, nb 1 tbz 0, cow 0, newSinceEpoch 1, zla 1, bs 1048576

查到的 3440b5ca5488 即是 MAC 34:40:b5:ca:54:88, 然後去找那一台的 HOST 主機

示意圖:

Step 03： 兩種解決方法

方法一:
確定主機後, 在 vCenter 將 host 進入 maintenance mode, 此時 DRS vMotioned all VMs to another host in the cluster , 然後 restarted the hostd service.

SSH 登入主機, 下指令: /etc/init.d/hostd restart

方法二:

若覺得  maintenance mode 要將所有 guest 移到別台 Host 工程太浩大, 那就

將 guest 移到這台Host, 再作 Consolidation 也是可以.

個人是覺得第二個方法最方便. 供參考

        </td>
        <td>
            {% if (file.deleteUrl) { %}

                    <i class="glyphicon glyphicon-trash" style="font-size: 12px"></i>
                    <span>${action.getText('common.btn.delete')}</span>
                </button>
                <input type="checkbox" name="delete" value="1" class="toggle">
            {% } else { %}
                <button class="btn btn-warning btn-sm cancel">
                    <i class="glyphicon glyphicon-ban-circle" style="font-size: 12px"></i>
                    <span>${action.getText('common.upload.cancel')}</span>
                </button>
            {% } %}
        </td>
    </tr>
{% } %}

        }
        writer.print(gsonString);
        writer.flush();
        writer.close();
   }
}

Step 07: 檔案下載的 class: FileOutput

package com.gussh.common.utils;

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class FileOutput extends ActionSupport {

   static Logger logger = Logger.getLogger(FileOutput.class);

   @Resource(name="BA_TOOLS")
   protected BA_TOOLS baTools;
   public HttpServletRequest request = ServletActionContext.getRequest();
   public HttpServletResponse response = ServletActionContext.getResponse();

   private InputStream inputStream ;
   private String name;

   public InputStream getInputStream() {

       String filenamedownload = "";
       String filePath="/upload/";
       String osName = System.getProperty("os.name");

       if (!osName.equals("Linux")) {
           filePath = "C:" + filePath;
       }

       filenamedownload = filePath+ "/" + this.getName();

       try{
           File file = new File(filenamedownload);
           if(file.length()>0)
               inputStream = new FileInputStream(filenamedownload);
           else
               inputStream = new ByteArrayInputStream("No Files".getBytes());
       }catch(Exception e){
           e.printStackTrace();
       }


       //return ServletActionContext.getServletContext().getResourceAsStream(filenamedownload);
       return inputStream;
   }

   public String execute() throws Exception {
       return "success";
   }

    public String getDownloadFileName() {

        String downFileName = name;
        try {
            downFileName = new String(downFileName.getBytes(), "ISO8859-1");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return downFileName;

    }

   public String getName() {
       return name;
   }

   public void setName(String name) {
       this.name = name;
   }

}

Step 08: file upload 的 javascript

$(document).ready(function () {

    // Initialize the jQuery File Upload widget:
   $('.fileupload').each(function (e, data) {
        $(this).fileupload({
            dropZone: $(this)
        });
        $('#reqCode').val('fileUpload');
   });

   /*處理每一個檔案上傳前, 加入單一 fileDescription 的值*/
   $('.fileupload').bind('fileuploadsubmit', function (e, data) {

       // 剔除欄位:fileDescription 後, 取得所有要上傳的值
       var allInputs = $( ":input[name!='fileDescription']" );
       // 抓取 id="template-upload" 裡新增加單一的 input 欄位: fileDescription
       var fileUploadInputs = data.context.find(':input');
       // 兩個 array 再 merge , 就是所有欄位要上傳的所有值
       var inputs = $.merge(allInputs,fileUploadInputs);

        if (inputs.filter(function () {
                return !this.value && $(this).prop('required');
            }).first().focus().length) {
            data.context.find('button').prop('disabled', false);
            return false;
        }
        // 上傳的欄位值需要序列化, 才會逐一上傳
        data.formData = inputs.serializeArray();
   });

});

大致的作業如上.

Struts2 的異常處理 Exception & UnknownHandler & UnderConstruction

在 Struts2 的異常處理有兩種，一種是程式撰寫的邏輯出錯，另一種是找不到 action Name : There is no Action mapped for namespace...，避免系統出錯的改善作法如下：

程式撰寫的邏輯出錯：

在 Struts.xml 內加入

<global-results>
<result name="error">/error.jsp</result>
</global-results>

<global-exception-mappings>
<exception-mapping exception="java.lang.Exception" result="error"/>
</global-exception-mappings>

建立 error.jp 檔案

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>An unexpected error has occurred</title>
</head>
<body>

   <h3>The application has malfunctioned(該應用程序出現錯誤)</h3>

   <p>Please contact technical support with the following information(請聯繫資訊單位並提供以下信息)：</p>

   <h4>
       Exception Name:<s:property value="exception" />
   </h4>

   <h4>
       Exception Details:<s:property value="exceptionStack" />
   </h4>

</body>
</html>

一種是找不到 action Name：

有兩個方法可以解決

第一種是方法利用 default-action-ref：

在 Struts.xml 內加入

<default-action-ref name="UnderConstruction"/>

<action name="UnderConstruction">
<result>/UnderConstruction.jsp</result>
</action>

建立 UnderConstruction.jp 檔案

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@page import="org.apache.struts2.ServletActionContext"%>
<%@page import="com.opensymphony.xwork2.ActionContext"%>
<%@page import="java.util.*"%>
<%@page import="java.net.*"%>
<%@page import="java.text.MessageFormat"%>
<%@page import="com.gussh.common.utils.*"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>

<%

String username = (String)session.getAttribute("USERNAME");
String password = (String)session.getAttribute("PASSWORD");
String language = (String)request.getSession().getAttribute("loginLanguage");
String progModule = (String)session.getAttribute("progModule");
String actionName= "";
String actionURL= "";

ActionContext actionContext = ServletActionContext.getContext();
actionName = actionContext.getName();

actionURL="http://polinwei.blogspot.tw/login.do";



%>
<body>

<%if(username != null){%>
   <form name="ssoForm" action="<%=actionURL %>" target='_blank'>
   <input type="hidden" name="username" value="<%=username %>" />
   <input type="hidden" name="password" value="<%=password %>" />
   <input type="hidden" name="language" value="<%=language %>" />
   </form>
   <script type="text/javascript">
   var formObj=document.ssoForm;
   formObj.method='post';
   formObj.submit();
   document.location.href="<%=request.getContextPath()%>/Index?reqCode=moduleSelect&progModule=<%=progModule%>"
   </script>
<% }else{ %>
   <script type="text/javascript">
       window.opener.top.document.location.href="<%=actionURL %>";
       window.opener=null;
       window.open("","_self");
       window.close();
   </script>
<% }%>
</body>
</html>

第二種作法則是利用 unknown-handler-stack：

在 Struts.xml 內加入

class="com.sc.actions.UnderConstructionAction"

package com.gussh.sc.actions;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.dispatcher.ServletDispatcherResult;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.Result;
import com.opensymphony.xwork2.UnknownHandler;
import com.opensymphony.xwork2.XWorkException;
import com.opensymphony.xwork2.config.entities.ActionConfig;

public class UnderConstructionAction implements UnknownHandler {
   // 網頁會使用的 request, response, session
   public HttpServletRequest request = ServletActionContext.getRequest();
   public HttpServletResponse response = ServletActionContext.getResponse();
   public Map<String, Object> session = ActionContext.getContext().getSession();

   public ActionConfig handleUnknownAction(String namespace, String actionName)
           throws XWorkException {

       ActionConfig actionConfig = null;
       request.setAttribute("actionName",actionName);

       return actionConfig;

   }

   public Result handleUnknownResult(ActionContext actionContext,
           String actionName, ActionConfig actionConfig, String resultCode)
           throws XWorkException {
        actionContext.put("action", actionName);
        actionContext.put("result", resultCode);
        request.setAttribute("actionName",actionName);
        return new ServletDispatcherResult("/templates/SSO/GUSSO.jsp");
   }

   public Object handleUnknownActionMethod(Object action, String methodName)
           throws NoSuchMethodException {
       // TODO Auto-generated method stub
       return null;
   }

}

JSP - EL 基本用法

JSP 的 EL 與 JSF 的 EL( 如 JSF EL ( Expression Language ) 的介紹)，大致相同，參考 http://penguin1989930.pixnet.net/blog/post/236537248 ，後整理如下：

使用EL存取資料
如果想要顯示application隱含物件中的count變數時，可以使用JSP這樣做：
<%=application.getAttribute("count")%>

而也可以透過EL這樣做：
${count}
或
${applicationScope.count}

您可以發現EL真的讓JSP的程式碼簡潔了許多。其中applicationScope代表示application隱含物件中的資料集合（並不等於application物件），而EL顯示集合的方法有三種：
${applicationScope.count}
${applicationScope['count']}
${applicationScope["count"]}

1.存取資料的預設物件有：★★★

EL預設物件	對應的JSP隱含物件集合
applicationScope	application集合
sessionScope	session集合
pageScope	page集合
requestScope	request集合
pageContext	pageContext物件

存取資料時，如果沒有指定範圍，會依照pageContext >> request >> session >> application的順序來顯示資料，例如：

<%
session.setAttribute("username","jack");
application.setAttribute("username","mary");
%>

${username}

由於session與application兩者都擁有username變數值，所以EL會依照先後順序來顯示資料(session >> application)，所以上述程式便會輸出 jack。
如果想要取得web.xml所設定的初始變數值，可以利用initParam預設物件來完成，請看以下範例：

使用JSP	使用EL
<%=application.getInitParameter("host")%>	${initParam}

2. 利用EL接收網頁傳遞過來的資料 ★★★

接收網頁傳遞過來的資訊可使用EL所提供的預設物件

EL預設物件	對應的JSP的方法
param	request.getParameter()
paramValues	request.getParameterValues()

如果要顯示網頁傳遞過來的變數：

使用JSP	使用EL
<%=request.getParamater("username")%>	${param.username}

如果要顯示網頁傳遞過來的變數：(該變數為陣列時)

使用JSP

使用EL

<%

String[] paper = request.getParamaterValues("paper");

out.print("第一個項目:"+paper[0]);

%>

${paramValues.paper[0]}

3. 利用EL取得cookie資料

如果使用JSP來取得cookie中的username，可以使用以下程式碼：

Cookie[] ck = request.getCookies();
if (ck != null) {
for (int i = 0; i < ck.length; ++i)
if (ck[i].getName().equals("username")) {
out.print(ck[i].getValue());
break;
}
}

但如果使用EL的預設物件-cookie，就可以簡化成：
${cookie.username.value}

4. 利用EL取得網頁標頭資訊

取得標頭用EL所提供的預設物件

EL預設物件	對應的JSP的方法
header	request.getHeader()
headerValues	request.getHeaders()

舉例來說，如果想要取得目前網站主機名稱，可以使用以下方法：

使用JSP	使用EL
<%=request.getHeader("host")%>	${header.host}
<%=request.getContextPath() %>	${request.contextPath}

運用如下：

Struts2: 在freemark頁面裡嵌入action class & parameters

在 freemark 的頁面要嵌入 action 及參數( Parameters) 有兩種方式

1. 使用 struts2 tag: action

<img width='100px' src='
   <@s.action name="Picout" executeResult="success">
           <@s.param name="name">${Session.userInfo['PHOTO_PATH']}</@s.param>
   </@s.action>
'/>

2. 使用 struts2 tag: url

<img width='100px' src='<@s.url action="Picout"><@s.param name="name">${Session.userInfo['PHOTO_PATH']}</@s.param></@s.url>' />

個人建議使用第2種方法較為方便

參考: http://www.mkyong.com/struts2/struts-2-url-tag-example/

Windows Server 2012 AD 移除 Sub Domain 的方法

Windows Server 2012 AD 移除 Sub Domain 的方法，有兩種方式：

方法一：利用 ntdsutil 指令

ntdsutil 指令操作說明如下

實作如下：

若移除不成功，則用 方法二：利用精靈 的強制移除

方法二：利用精靈

Step 01: 選擇啟動[移除角色及功能精靈]

Step 02：將 Active Directiory..的 Check Box 的勾移除，系統跳出提示視窗，選 "移除功能"

Step 03: 再選 "將此網域控制站降級"

後續可以先嚐試正常的降級方式，若降級不下來，再使用強制降級

Java 對於LDAP: Windows Server AD (Active Directory) 的認證整合

Java 要對 Windows Server AD (Active Directory) 的認證整合，程式碼如下：

Step 01: 準備一個共用函數 LDAP_AUTH_AD

    /**
   * AD LDAP 登入認證
   *
   * @param ldap_url
   *            like ldap://912.168.2.1:389/DC=WEI,DC=COM
   * @param account
   * @param password
   * @return String[2] array 0 :0 success,1 fail,2 LDAP connect fail,3 unknow
   *         error array 1 :useremail
   */
   public String[] LDAP_AUTH_AD(String ldap_url, String account, String password) {
       String[] returnStr = new String[2];
       Hashtable<String, String> env = new Hashtable<String, String>();
       env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
       env.put(Context.PROVIDER_URL, ldap_url);
       env.put(Context.SECURITY_AUTHENTICATION, "simple");
       env.put(Context.SECURITY_PRINCIPAL, account);
       env.put(Context.SECURITY_CREDENTIALS, password);

       LdapContext ctx = null;
       try {
           ctx = new InitialLdapContext(env, null);
           returnStr[0] = "0";

           SearchControls searchCtls = new SearchControls();
           searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);
           String searchFilter = "(sAMAccountName=" + account + ")";

           String searchBase = "";
           int totalResults = 0;

           String returnedAtts[] = { "mail" };
           searchCtls.setReturningAttributes(returnedAtts);
           try {
               NamingEnumeration answer = ctx.search(searchBase, searchFilter, searchCtls);

               while (answer.hasMoreElements()) {
                   SearchResult sr = (SearchResult) answer.next();
                   Attributes Attrs = sr.getAttributes();
                   if (Attrs != null) {
                       try {
                           for (NamingEnumeration ne = Attrs.getAll(); ne.hasMore();) {
                               Attribute Attr = (Attribute) ne.next();
                               for (NamingEnumeration e = Attr.getAll(); e.hasMore(); totalResults++) {
                                   returnStr[1] = e.next().toString();
                               }

                           }
                       } catch (NamingException e) {
                           System.err.println("Throw Exception : " + e);
                       }
                   }
               }
               loger.debug("Number: " + totalResults);
           } catch (Exception e) {
               loger.error("Can't find Email Address");
           }

           return returnStr;
       } catch (javax.naming.AuthenticationException e) {
           returnStr[0] = "1";
           e.printStackTrace();
           return returnStr;
       } catch (javax.naming.CommunicationException e) {
           // System.out.println("Can't connect to ldap server!");
           returnStr[0] = "2";

           return returnStr;
       } catch (Exception e) {
           System.out.println("error");
           e.printStackTrace();
           returnStr[0] = "3";

           return returnStr;
       } finally {
           if (ctx != null) {
               try {
                   ctx.close();
               } catch (NamingException e) {

               }
           }
       }
   }

Step 02: 主程式

// 取得認證URL
String LDAP_URL="ldap://192.168.2.1:389/DC=WEI,DC=COM;WEI.COM";
LDAP_URL = LDAP_URL.split(";")[0];;
// 取得該公司網域
String AD_Domain="";
AD_Domain = "@"+LDAP_URL.split(";")[1].trim();

// AD認證方式登入
if(AUTH_METHOD.equalsIgnoreCase("AD") && !isLogin) {
   String[] as = baTools.LDAP_AUTH_AD(LDAP_URL, users.getUserName()+AD_Domain, users.getUserPassword());
   if (as[0].equals("0")) {
       isLogin = true;
       loginResult= SUCCESS;

   }else{
       this.addActionError("帳號登入錯誤");
   }
} // end AD認證方式登入

這樣就可以與您的公司的 AD (Active Directory) LDAP認證主機作整合.

JBOSS 與 Wildfly 常用設置

JBOSS & Wildfly 常用設置

1. JBoss伺服器改成支援外網訪問
在standalone.xml文件中找到

在這個下面加入

另外把1改成2
1 <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
2 <socket-binding-group name="standard-sockets" default-interface="any" port-offset="${jboss.socket.binding.port-offset:0}">

或改成

也可以用圖形管理界面來作修改，如下圖，將 Address Wildcard 設為：Any Address，並將 Inet Address 設為空值，不然會有錯誤。

JBoss interface 對外

修改管理介面的網址限制

jboss_manageIP

2. 訪問埠的更改
<socket-binding name="http" port="${jboss.http.port:80}"/>

3. 改為可以修改JSP頁面不用重啟

<servlet-container name="default">
<jsp-config/>
<websockets/>
</servlet-container>

改為

<servlet-container name="default">
<jsp-config development="true"/>
</servlet-container>

4. 部署的程式不用wildfly內置CXF包
在應用的WEB-INF目錄下面增加該檔：jboss-deployment-structure.xml

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<deployment>


<exclude-subsystems>
<subsystem name="webservices" />
</exclude-subsystems>
</deployment>
</jboss-deployment-structure>
