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安装配置手册

1、 相关网站

http://httpd.apache.org/：下载Apache 2.0.59；因为目前subversion推荐采用这个版本，更高版本可能存在一些问题；

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

http://tortoisesvn.tigris.org/：下载tortoisesvn1.4.3；svn客户端，与windows的资源管理器集成；

http://tortoisesvn.net/translation_status：下载tortoisesvn1.4.3中文语言包

2、 安装步骤

首先安装Apache 2.0.59，简单按提示安装即可；安装目录

其次安装subversion 1.4.3，简单按提示安装即可；

最后安装tortoisesvn1.4.3，简单按提示安装即可；

3、 配置步骤

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主要是增加以下内容：

                                                               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版本库根目录；在根目录下创建不同的项目目录

4.       AuthType Basic

5.       AuthName "Subversion repositories"

6.       AuthUserFile passwd #指定用户名密码文件，文件名为passwd；默认目录为apache安装目录“X:\Program Files\Apache Group\Apache2”

7.       AuthzSVNAccessFile svnacl.txt #指定访问控制文件，文件名为svnacl.txt；默认目录为apache安装目录“X:\Program Files\Apache Group\Apache2”

8.       Require valid-user

                                                             v.      </Location>

                                                           vi.      访问控制文件例子svnacl.txt：

1.       [groups]

2.       #定义不同的用户组

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是一个例子项目project

15.   [zyn:/] 

16.   @devteam1 = rw #表示组devteam1可以读写，即check in/out

17.   #test是另外一个例子项目project

18.   [test:/]

19.   @devteam2 = r # rw #表示组devteam2只读，即check out

c.       tortoisesvn1.4.3安装完成基本上不用配置；详细使用手册另行编写

管理 Eclipse 中的服务器

安装 Eclipse WTP 服务器适配器后，您可以使用 Eclipse 框架管理服务器。您可以

• 将服务器添加到 Eclipse 框架
• 启动（可启用调试，也可不启用调试）、停止和重新启动服务器。
• 从 Eclipse 包含的内部 Web 浏览器使用服务器的 Web 控制台。
• 将正在开发的 J2EE 资产部署到服务器，取消在服务器上的部署，或重新部署到服务器。
• 使用 Eclipse 调试功能，调试正在已启动的服务器（启用了调试功能）上运行的开发中的 J2EE 资产。

注：J2EE 透视图是使用 Eclipse 框架开发 J2EE 应用程序的首选透视图。 如果您不在 J2EE 透视图中，请单击 Windows，Open Perspective，Other... 在 Select Perspective 面板中，选择 J2EE，然后单击 OK，以切换到 J2EE 透视图。

启动 Web 控制台

通过以下过程，用 Eclipse 启动服务器的 Web 控制台。

1. 在 J2EE 透视图中，打开 Servers 视图。
2. 在 Server 面板上，右键单击要管理的服务器。
3. 在弹出的上下文菜单中，单击 Launch Community Edition Console

Unzip them and copy plugins into Eclipse.

3、Download Myfaces from apache.org

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

5、当然不能少了JDK from java.sun.com；

差不多就这样了，在Eclipse还要配置一下WAS CE。

详细文章参见 管理 Eclipse 中的WAS CE服务器。

J2SE在java.security.MessageDigest提供了一个MD5、SHA摘要计算类。
结合javascript的md5计算，可以实现前台口令加密，后台数据库中也保存的是md5或者sha的密码加密摘要。

具体实现如下：
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，具体的action和form就不再浪费纸张了，我定义了一个loginuser的类来进行用户密码校验，这里只给出校验的方法：
/**
  *
  * 校验密码，密码采用MD5算法加密。
  *
  * @Param PasswordInput, 待校验密码
  * @Return 校验通过返回true，否则返回false
  *
  *
  */
 public boolean CheckPassword(String PasswordInput) throws ATError {

  this.select();//从数据库中读取用户信息
  MessageDigest md;
  try {
   //生成一个MD5加密计算摘要
   md = MessageDigest.getInstance("MD5");

   //计算md5函数
   md.update(this.password.getBytes());
   //digest()最后确定返回md5 hash值，返回值为8为字符串。因为md5 hash值是16位的hex值，实际上就是8位的字符
   //BigInteger函数则将8位的字符串转换成16位hex值，用字符串来表示；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);
  }

 }

一开始觉得别人走得很远了，我们大概没有机会了。实际上不是这样，我们不光有成本优势，还有速度优势、技术优势，致使过去没有把我们的技术集成起来。
