jsp调用bean时的错误

vanone 2004-10-12 01:06:24

各位大侠，
我想用exmp.jsp调用bean1,
bean1.java 已经编译成bean1.class

bean1.java代码是-----------------------
import java.lang.object.*;

public class Bean1
{
public String name = "lucky man";

public String output()
{
return "Welcome" + name + "!";
}
}
----------------------------------------------------
exmp.jsp代码是
<html>
<head>
<title>
使用自己的Bean1
</title>
</head>
<body>
<jsp:usebean id = "Bean01" scope = "page" class = "bean.Bean1" />
<%= Bean01.output() %>
<hr>
<%
Bean01.name = "Dux";
%>
<%= Bean01.output() %>
</body>
</html>
-----------------------------------------------------------------------
当我启动tomcat运行exmp.jsp时候
报错是这样：500
org.apache.jasper.JasperException: /jsp/exmp.jsp(8,5) Invalid standard action
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)

javax.servlet.http.HttpServlet.service(HttpServlet.java:810)

另外我编译servlet的时候报错，说找不到java.lang.object，什么原因啊,
另外HttpServlet等什么也找不到，急啊，求救了。
