简单的java和jsp 问题!

huangzhong1 2003-09-29 04:47:16

我的java代码是:
package helloworld;

import java.io.*;
public class helloworld
{
public void getString()
{
System.out.println("helloword");
}
}

JSP代码是:
package helloworld;

import java.io.*;
public class helloworld
{
public void getString()
{
System.out.println("helloword");
}
}

运行的结果是:
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 14 in the jsp file: /jsp/new/first.jsp

Generated servlet error:
C:\tomcat\work\localhost\examples\jsp\new\first$jsp.java:63: ')' expected.
out.print(asd.getString(););
请问那里去错了。

java代码改成是:
package helloworld;

import java.io.*;
public class helloworld
{
public String getString()
{
return "helloword";
}
}

JSP代码改成

<html>

<title>MY FIRST JSP</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>

<body>
<jsp:useBean id="asd" scope="erquest" class="hel.helloworld"/>
<%@ page language="java"%>

<%=ads.getString()%>

</body>
</html>

jsp修改如下：

<%@ page language="java"%>
<html>
<head>
<title>MY FIRST JSP</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>

<body>
<jsp:useBean id="asd" scope="request" class="hel.helloworld"/>
<%=ads.getString()%>
</body>
</html>

out.print(asd.getString(););
变成:
out.print(asd.getString());
