求救贴:碰到过的帮帮忙了javabean出现unable to compile class for jsp (在线等)
试验一个小小的javabean程序   可是老是出现错误   代码如下:
TestBean.java:
package   test;

public   class   TestBean   {
String   name;
public   TestBean(){}
public   void   setName(String   name)
{
this.name=name;
}
public   String   getName()
{
return   this.name;
}
}
index.jsp
<%@   page   language= "java "   import= "test.TestBean "   %>
<html>    
    <head>    
        <title> My   JSP   'index.jsp '   starting   page </title>
    </head>
    <body>  
<jsp:useBean   id= "testBeanEx "   scope= "page "   class= "TestBean "/>
    </body>
</html>
运行信息:

Apache   Tomcat/6.0.10

tomcat6.0   下localhost:8080运行正常   其中实例运行正常   HelloWorld.java运行正常
配置了好久   就是不知道问题在哪里   高手指点下吧
