    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

    Example:
    abc 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    abc 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    tas 3420 3562 2123 1343 2176 7654 3252 8765 5643 3452
    aer 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    tas 3420 3562 2123 1343 2176 7654 3252 8765 5643 3452

    UNIX:

    display the no of occurance and the record
    > sort f1.txt|uniq -c
       2 abc 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
       1 aer 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
       2 tas 3420 3562 2123 1343 2176 7654 3252 8765 5643 3452

    display only the duplicate records
    > sort f1.txt|uniq -d
    abc 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    tas 3420 3562 2123 1343 2176 7654 3252 8765 5643 3452

    display distinct records
    > sort f1.txt|uniq
    abc 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    aer 1000 3452 2463 2343 2176 7654 3452 8765 5643 3452
    tas 3420 3562 2123 1343 2176 7654 3252 8765 5643 3452

    Reference:
    How to find Duplicate Records in a text file
    Shell: How To Remove Duplicate Text Lines

    Windows:

    Notepad++ can sort by line, and remove the duplicate lines at the same time.
    1. Open the menu under: TextFX-->TextFX Tools
    2. Make sure "sort outputs only unique..." is checked
    3. select a block of text (ctrl-a to select the entire document).
    4. click "sort lines case sensitive" or "sort lines case insensitive"

    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
