a wonderful Eclipse plugin:
WindowBuilder, which can be used to develope Swing/SWT UI:
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

1.安裝JAVA環境
sudo apt-get install sun-java5-jre
2.下載tomcat： http://tomcat.apache.org/
3.解壓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.啟動tomcat
$sudo /opt/tomcat/bin/startup.sh
如果能看到下列提示，就表明啟動成功了！
>Using CATALINA_BASE: /opt/tomcat
>Using CATALINA_HOME: /opt/tomcat
>Using CATALINA_TMPDIR: /opt/tomcat/temp
>Using JRE_HOME: /usr/lib/j2sdk1.5-sun
打開Firefox，在地址欄中輸入http://localhost:8080，如果出來Tomcat的缺省界面，說明測試通過！
5.停止Tomcat服務
$sudo /opt/tomcat/bin/shutdown.sh
1.下載安裝 RubyInstaller： http://rubyforge.org/frs/?group_id=167&release_id=46588
2. 檢查 RubyGems 版本，須高于 1.3.6
gem -v
3.如果版本不是最新，可以通過下面的命令更新至最新版本：
gem update --system
gem uninstall rubygems-updatｅ
４.安裝 Rails：
gem install rails
1.按照github上的指南配置（
http://help.github.com/win-set-up-git/）基礎的git環境。
2.在github上創建一個Repository。
3.在Eclipse中通過“Eclipse Marketplaces”，在Market Places里安裝egit。
4.在Eclipse中生public key, 并添加到GitHub Repository中。
Eclipse中通過：performance -> SSH2 -> Key Management -> Gernerate RSA Key 生成 SSH 的 public key。
在GitHub中通過：edit your profile -> ssh key -> Add SSH Key 添加SSH Key, 把上面生成的 public key 拷貝到這里，保存。
5.Eclipse里File菜單，Import，即可從git導入剛添加到git的項目了。
6.修改，并提交。在項目上點右鍵–>team–>commit。commit是commit到本機的git庫，而push才是同步到github。
1.下載最新版 Eclipse:
官方下載：http://www.eclipse.org/downloads/
2.解壓下載的壓縮包：
$sudo tar xvfz eclipse-SDK-3.1.2-linux-gtk.tar.gz -C /opt
這個時候，就可以在 /opt 文件夾中看到出現了一個eclipse的文件夾，雙擊其中的eclipse文件就可以運行eclipse了。
3.在菜單設置Eclipse選項： $gedit ~/.local/share/applications/eclipse-user.desktop
