Installing the Beryl Packages

Beryl on Edgy Eft

Install the following packages:

sudo apt-get install beryl emerald-themes

Note: Beryl is a metapackage that will install all the dependencies (beryl-core, beryl-plugins, beryl-manager, beryl-settings) and also the decoration themes (emerald but not emerald-themes).

Beryl on Dapper Drake

Install the following packages:

sudo apt-get install xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 beryl emerald-themes

Note: Beryl is a metapackage that will install all the dependencies (beryl-core, beryl-plugins, beryl-manager, beryl-settings) and also the decoration themes (emerald but not emerald-themes).

Beryl on Feisty Fawn

Install the following packages:

sudo apt-get install beryl

Note: Beryl is a metapackage that will install all dependencies and decoration themes).

Starting Beryl

Now it's time to test Beryl. Open a terminal, and invoke:

beryl-manager

If all goes well, Beryl should show a splash screen, and your windows will suddenly become wobbly! Also note that there is a new icon, a red gem, in your system tray - this allows you to control Beryl, run the Beryl settings manager or Emerald (the theme manager). It also provides fallback to a different window manager, in case Beryl crashes (remember Beryl is very much alpha software).

If you don't get a splash screen immediately, you may need to tell the manager to load Beryl - right-click on the icon in the system tray, go to "Select Window Manager" and choose "Beryl". If that doesn't work, there's a problem somewhere! Hopefully, useful debugging output will be in the terminal session; ask for help on the #ubuntu-xgl or #xgl channels on irc://irc.freenode.net/

Making Beryl start automatically when you log in (GNOME)

From the menu at the top of your screen, select "System > Preferences > Sessions". Click on the right-most tab, "Startup Programs".

Now create a new entry for beryl:

beryl-manager

Close the Session Preference Panel. Beryl will now start automatically when you log in.

Troubleshooting

If you find that you cannot set icon or gtk themes while using beryl with Xgl on display :1, invoke the following command in a terminal:

gnome-settings-daemon &

Your chosen theme should now appear.

The console message

beryl: water: GL_ARB_fragment_program is missing

points to an OpenGL extension that your card cannot use. Simply switch off the water effect in the Beryl Settings Manager.

You might find that when you try to start beryl that you get the following:

chris@ubuntu:~$ beryl

I fixed this by creating the following shell script in /usr/local/bin/start-beryl and adding it to the startup programs in Gnome.

#!/bin/bash
LD_PRELOAD=/usr/lib/fglrx/libGL.so.1.2.xlibmesa /usr/bin/beryl &
gtk-window-decorator --replace &
xmodmap -e \"keycode 22 = BackSpace Delete\"

Many thanks to Michele Campeotto, who discovered this workaround for compwiz. From Michele's page:

"the problem is that ATI hasn’t yet released a driver with that new extension that Novell and Nvidia developed specifically for Xgl and compiz.

The extension is implemented by Mesa though, so we need get compiz to use that. The problem is that when you install the fglrx driver it overwrites /usr/lib/libGL.so.1.2 with its own version wich lacks this feature."

3D Nvidia Video Card Driver

No Nvidia Video cards have 3D acceleration enabled automatically with Ubuntu, because the manufacturer does not release open source drivers. However, it is possible to activate 3D acceleration. The process depends on which type of video card you have.

3D ATI Video Card Driver

Many ATI video cards work well with Ubuntu automatically. To check that 3d acceleration works with your card, see the section called “Introduction to 3D Video Acceleration”. If it does not work, this procedure should activate it.

Java 1.6 is also available, and can be installed by following the above directions, swapping all instances of 1.5 to 1.6

It is very likely that you will not want to have the Geronimo server process under the super user root. The following are a series of simple steps for changing the ownership and permissions for the required files in order to run Geronimo with a different user.

The following tasks should be performed while logged as root or a user with enough access rights.

1. create a new user (i.e. gmo) and add it to a specific user group. You could use the predefined www user group for instance.
2. edit the .bashrc for the user you just created and add the PATH and JAVA_HOME variables:
   PATH=$PATH:<java_home>/bin
   export PATH
   JAVA_HOME=<java_home>
   export JAVA_HOME
3. change the user group to all the subdirs in <geronimo_home>
   chown -R root:www <geronimo_home>
4. create a deploy directory within the <geronimo_home> directory structure.
5. change the access permissions to the following directories
   chmod -R 774 <geronimo_home>/bin
   chmod -R 774 <geronimo_home>/deploy
   chmod -R 774 <geronimo_home>/repository
   chmod -R 774 <geronimo_home>/var
6. login as the new user (i.e. gmo)
7. cd <geronimo_home>/bin
8. ./geronimo.sh run

You are now able to run and deploy applications with a user other than root.

SubVision安裝配置手冊

1、 相關網站

http://httpd.apache.org/：下載Apache 2.0.59；因為目前subversion推薦采用這個版本，更高版本可能存在一些問題；

http://subversion.tigris.org/：下載subversion 1.4.3；

http://tortoisesvn.tigris.org/：下載tortoisesvn1.4.3；svn客戶端，與windows的資源管理器集成；

http://tortoisesvn.net/translation_status：下載tortoisesvn1.4.3中文語言包

2、 安裝步驟

首先安裝Apache 2.0.59，簡單按提示安裝即可；安裝目錄

其次安裝subversion 1.4.3，簡單按提示安裝即可；

最后安裝tortoisesvn1.4.3，簡單按提示安裝即可；

3、 配置步驟

a.       Apache 2.0.59基本上不需要配置

b.      subversion 1.4.3：主要配置是修改apache的配置文件httpd.conf主要是增加以下內容：

                                                               i.      LoadModule dav_svn_module "e:/Program Files/Subversion/bin/mod_dav_svn.so"

                                                             ii.      LoadModule authz_svn_module "e:/Program Files/Subversion/bin/mod_authz_svn.so"

                                                            iii.       

                                                           iv.      <Location /svn>

1.       DAV svn

2.       SVNListParentPath on

3.       SVNParentPath e:\SVN  #指定svn版本庫根目錄；在根目錄下創建不同的項目目錄

4.       AuthType Basic

5.       AuthName "Subversion repositories"

6.       AuthUserFile passwd #指定用戶名密碼文件，文件名為passwd；默認目錄為apache安裝目錄“X:\Program Files\Apache Group\Apache2”

7.       AuthzSVNAccessFile svnacl.txt #指定訪問控制文件，文件名為svnacl.txt；默認目錄為apache安裝目錄“X:\Program Files\Apache Group\Apache2”

8.       Require valid-user

                                                             v.      </Location>

                                                           vi.      訪問控制文件例子svnacl.txt：

1.       [groups]

2.       #定義不同的用戶組

3.       admin = admin

4.       devteam1 = admin

5.       devteam2 = admin

6.        

7.       # Default access rule for ALL repositories

8.       # Everyone can read, admins can write, Dan German is excluded.

9.       [/]

10.   * = r

11.   @admin = rw

12.   dangerman =

13.   # Allow developers complete access to their project repos

14.   #zyn是一個例子項目project

15.   [zyn:/] 

16.   @devteam1 = rw #表示組devteam1可以讀寫，即check in/out

17.   #test是另外一個例子項目project

18.   [test:/]

19.   @devteam2 = r # rw #表示組devteam2只讀，即check out

c.       tortoisesvn1.4.3安裝完成基本上不用配置；詳細使用手冊另行編寫

管理 Eclipse 中的服務器

安裝 Eclipse WTP 服務器適配器后，您可以使用 Eclipse 框架管理服務器。您可以

• 將服務器添加到 Eclipse 框架
• 啟動（可啟用調試，也可不啟用調試）、停止和重新啟動服務器。
• 從 Eclipse 包含的內部 Web 瀏覽器使用服務器的 Web 控制臺。
• 將正在開發的 J2EE 資產部署到服務器，取消在服務器上的部署，或重新部署到服務器。
• 使用 Eclipse 調試功能，調試正在已啟動的服務器（啟用了調試功能）上運行的開發中的 J2EE 資產。

注：J2EE 透視圖是使用 Eclipse 框架開發 J2EE 應用程序的首選透視圖。 如果您不在 J2EE 透視圖中，請單擊 Windows，Open Perspective，Other... 在 Select Perspective 面板中，選擇 J2EE，然后單擊 OK，以切換到 J2EE 透視圖。

啟動 Web 控制臺

通過以下過程，用 Eclipse 啟動服務器的 Web 控制臺。

1. 在 J2EE 透視圖中，打開 Servers 視圖。
2. 在 Server 面板上，右鍵單擊要管理的服務器。
3. 在彈出的上下文菜單中，單擊 Launch Community Edition Console

3、Download Myfaces from apache.org

4、Download WAS CE & Eclips plugin from IBM, Install them.

5、當然不能少了JDK from java.sun.com；

差不多就這樣了，在Eclipse還要配置一下WAS CE。

詳細文章參見 管理 Eclipse 中的WAS CE服務器。

J2SE在java.security.MessageDigest提供了一個MD5、SHA摘要計算類。
結合javascript的md5計算，可以實現前臺口令加密，后臺數據庫中也保存的是md5或者sha的密碼加密摘要。

具體實現如下：
1、login.jsp部分
...
<script type="text/javascript" src='js/md5.js'>

</script>

<html:form action="/login" focus="userid" >

<table class="SubFormStyle">
   <tr align=left>
    <td><bean:message key="caption.LOGIN.UserID" /> <html:text
     property="userid" value=""></html:text></td>
    <td><bean:message key="caption.LOGIN.Password" /> <html:password
     property="passwordinput" value=""></html:password>
     <html:hidden
     property="password" value="" ></html:hidden></td>
    <td><html:submit onclick="password.value = hex_md5(passwordinput.value);">
     <bean:message key="button.Login" />
    </html:submit></td>

   </tr>
</table>
</html:form>
...

2、我用的是struts，具體的action和form就不再浪費紙張了，我定義了一個loginuser的類來進行用戶密碼校驗，這里只給出校驗的方法：
/**
  *
  * 校驗密碼，密碼采用MD5算法加密。
  *
  * @Param PasswordInput, 待校驗密碼
  * @Return 校驗通過返回true，否則返回false
  *
  *
  */
 public boolean CheckPassword(String PasswordInput) throws ATError {

  this.select();//從數據庫中讀取用戶信息
  MessageDigest md;
  try {
   //生成一個MD5加密計算摘要
   md = MessageDigest.getInstance("MD5");

   //計算md5函數
   md.update(this.password.getBytes());
   //digest()最后確定返回md5 hash值，返回值為8為字符串。因為md5 hash值是16位的hex值，實際上就是8位的字符
   //BigInteger函數則將8位的字符串轉換成16位hex值，用字符串來表示；得到字符串形式的hash值
   String pwd = new BigInteger(1, md.digest()).toString(16);
   
   if (PasswordInput.equals(pwd)) {
    return true;
   } else {
    return false;
   }
  } catch (NoSuchAlgorithmException e) {
  
   throw new ATError(e, "LoginUser", "CheckPassword", 1000);
  }

 }

一開始覺得別人走得很遠了，我們大概沒有機會了。實際上不是這樣，我們不光有成本優勢，還有速度優勢、技術優勢，致使過去沒有把我們的技術集成起來。
