所有的初步配置应该没问题，因为jsp能正常运行。
我的配置如下：
jdk1.4；Tomcat5.0.19；系统win2000pro+IIS5
建立了自己的虚拟目录，在server.xml中加入了以下语句：
.......
<Context path="/test" docBase="c:\test" debug="0" reloadable="true"/>
</Host>

问题：
在c:\test中建立了jspTest目录,在其下建立了myJsp.jsp文件、WEB-INF目录、WEB-INF\classes目录、在\classes下建立了myBean.java。

//myBean.java
package beans;
import java.io.*;

public class myBean
{
private int item=10;
public int getItem()
{
return item;
}
public void setItem(int x)
{
item=x;
}
public void increment()
{
item++;
}
}

//myJsp.jsp

<html>
<head>
<title>Test</title>
</head>
<body>
<jsp:useBean id="t1" class="beans.myBean" scope="session" />
<%
int value=t1.getItem();
out.println("<br>useBean:"+"item的值是"+value);
%>
<jsp:setProperty name="t1" property="item" value="20"/>
<%
out.println("<br>useBean:"+"setProperty的值是"+t1.getItem());
%>
</body>
</html>

myBean.java编译正常，在classes下面产生了beans文件夹，并在此文件夹下面生成myBean.class文件，但在运行 http://localhost:8080/test/jspTest/myJsp.jsp是出现错误提示。

错误提示：

org.apache.jasper.JasperException: Unable to compile class for JSP

此问题研究了两天未果，包括看帖子，请高手指点迷津！
