java.lang.ArrayIndexOutOfBoundsException:   195  
   
  明明是数组越界了  
  贴出你的源代码来看看Top

楼上的兄弟说的对，不是你的配置有问题，而是你的代码有问题，出现了数组越界的异常。  
  仔细检查你的代码！！！Top

程序写得有问题,服务器报告不能编译,就已经表示找到javabean了

你以后可以先做一个demo，简单点，保证对就行了。Top

把javabean看成一个普通的类就行了

可能是数组赋值或取值时循环超出数组下标Top

检查一下JAVABEANTop

源程序如下：  
  javabean：  
  package   db;  
   
  public   class   tt  
  {  
  private   String   s;  
   
  public   tt()  
  {  
  s="sfja;aslkfajs;";  
  }  
   
  public   void   setstr(String   ss)  
  {  
  s=ss;  
  }  
   
  public   String   getstr()  
  {  
  return   s;  
  }  
   
  /*public   static   void   main(String[]   args)  
  {  
  tt   e=new   tt();  
  //e.getstr();  
                  System.out.println(e.getstr());  
  }*/  
  }Top

  <html>  
  <head>  
  <title>ww</title>  
  </head>

搞定了，原来是jsp文件末尾多了个"<"，这也有影响？结贴Top
