再次谢谢yangxiao_jiang。但我不是不了解是怎么回事。比如我们在Delphi里调试的时候，如果没有按F7它是不会跟踪到VCL里的代码的。但ECLIPSE里就会这样吗？还是说我的代码有问题呢？yangxiao_jiang能帮我看一下这个代码吗？我也是从网上拷下来的：
get.jsp
<html>
<body>
<form>
<jsp:useBean id="staffBean"
class="StaffBean"
scope="session"
/>
<table border="1">
<tbody>
<tr>
<td width="120">Employee ID</td>
<td width="100">Name</td>
</tr>
<tr>
<td><jsp:getProperty name="staffBean"
property="ID"

<td><jsp:getProperty name="staffBean"
property="name"
