WindowBuilder is built as a plug-in to Eclipse and the various Eclipse-based IDEs (RAD, RSA, MyEclipse, JBuilder, etc.). The plug-in builds an abstract syntax tree (AST) to navigate the source code and uses GEF to display and manage the visual presentation.

Develop Java graphical user interfaces in minutes for Swing, SWT, RCP and XWT with WindowBuilder Pro's WYSIWYG, drag-and-drop interface. Use wizards, editors and intelligent layout assist to automatically generate clean Java code, with the visual design and source always in sync.

The project website: http://www.eclipse.org/windowbuilder/

To install the plugin in Eclipse: http://www.eclipse.org/windowbuilder/download.php

sudo apt-get install sun-java5-jre

2.下载tomcat： http://tomcat.apache.org/

3.解压tomcat

$sudo tar zxvf apache-tomcat-7.0.26.tar.gz -C /opt
$sudo mv /opt/apache-tomcat-7.0.26.tar.gz /opt/tomcat

4.启动tomcat

$sudo /opt/tomcat/bin/startup.sh

如果能看到下列提示，就表明启动成功了！

>Using CATALINA_BASE: /opt/tomcat
>Using CATALINA_HOME: /opt/tomcat
>Using CATALINA_TMPDIR: /opt/tomcat/temp
>Using JRE_HOME: /usr/lib/j2sdk1.5-sun

打开Firefox，在地址栏中输入http://localhost:8080，如果出来Tomcat的缺省界面，说明测试通过！

5.停止Tomcat服务

$sudo /opt/tomcat/bin/shutdown.sh

gem -v

　　mysql -u root

　　mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

方法2：用mysqladmin

　　mysqladmin -u root password "newpass"

　　如果root已经设置过密码，采用如下方法

　　mysqladmin -u root password oldpass "newpass"

方法3： 用UPDATE直接编辑user表

　　mysql -u root

　　mysql> use mysql;

　　mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';

　　mysql> FLUSH PRIVILEGES;

方法4： 在丢失root密码的时候，可以这样

　　mysqld_safe --skip-grant-tables&

　　mysql -u root mysql

　　mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';

　　mysql> FLUSH PRIVILEGES;

经测试，方法三修改成功，其他三种方法没有测试。

• Using FindBugs to scan the code and save the result as XML file

• the XML report is in a bad format for reading, we can use XSL file to make it easy and clear to read:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="summary.xsl"?>

• Use Internet Explore to open the XML report, now we get a report:

Note: FindBugs provided following xsl files for different format:

1、default.xsl；
2、fancy.xsl；
3、fancy-hist.xsl；
4、plain.xsl；
5、summary.xsl；
