netbeans IDE 5.5 RUN問題（RUN時出錯）
RUN時出錯，無論是什麼程序
簡單的程序程序：
public   class   NewClass   {

/**   Creates   a   new   instance   of   NewClass   */
public   NewClass()   {
}
public   static   void   main(String   args[]){
System.out.println( "asdasdasdasd ");
}
}
RUN時出錯:
ERROR   -   Ant   is   misconfigured   and   cannot   be   run.
java.lang.NullPointerException

------解决方案--------------------
我以前用bate版本,也有这样的问题.
换了版本就OK了!
