上面那个程序的代码就是一个JAVA程序，很简单啊，如下，文件名为TestBean.java，
将TestBean.java放在c:\test下，使用如下命令编译：
C:\Test>javac TestBean.java
然后在c:\Test下会产生一个编译后的bean文件：TestBean.class
将TestBean.class文件剪切到 %CATALINA_HOME%\webapps\myapp\WEB-INF\classes\test下

最后测试就会出现楼顶的问题，请问，是怎么回事啊？

package test;
public class TestBean{
private String name = null;
public TestBean(String strName_p){
this.name=strName_p;
}
public void setName(String strName_p){
this.name=strName_p;
}
public String getName(){
return this.name;
}
}

楼上的意思，是调用那个BEAN的程序写的不对？就是下面这个TestBean.jsp 的调用格式不对吗？

新建一个TestBean.jsp文件，文件内容为：
<%@ page import="test.TestBean" %>
<html><body><center>
<%
TestBean testBean=new TestBean("This is a test java bean.");
%>
Java bean name is: <%=testBean.getName()%>
</center></body></html>
