#小標=編譯及執行客戶端測試程式

 
===========<box>======================
    set J2EEPATH=C:\j2sdkee1.3.1\lib\j2ee.jar;HelloWorldAppClient.jar
    javac  -classpath %J2EEPATH% HelloWorldClient.java

  編譯成功之後，接著我們以下列執行指令進行客戶端測試程式的執行過程。

    set J2EEPATH=.;C:\j2sdkee1.3.1\lib\j2ee.jar;HelloWorldAppClient.jar
    java -classpath "%J2EEPATH%" HelloWorldClient

  如果執行成功，就會在目前的命令提示字元視窗裡，秀出"Hello World!中文一定成功"字樣訊息。
