看了好多，就是不行。大家HELP！在线

如果有包名，在classes下要建立以包名为文件名的文件夹！
再把bean放进去就ok了！你ok了吗？：）

同意楼上的说法，从提示上看好像根本就没找到类文件，按你所说的文件的路径应该是C:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\classes\test\dddBean.class
是啊，我放的啊。
就是不行啊。我看到在CSDN上有些这样的问题，但是都没有解决啊。
package test;public class Jsp1Bean {
  private String sample = "Start value";
  //Access sample property
  public String getSample() {
    return sample;
  }
  //Access sample property
  public void setSample(String newValue) {
    if (newValue!=null) {
      sample = newValue;
    }
  }
}<%@ page contentType="text/html; charset=GBK" %>

<head>

</head>
<jsp:useBean id="Jsp1BeanId" scope="session" class="test.Jsp1Bean" />
<jsp:setProperty name="Jsp1BeanId" property="*" />
<body>
<h1>

<form method="post">

<input type="reset" value="Reset">
<br>
Value of Bean property is :<jsp:getProperty name="Jsp1BeanId" property="sample" />
</form>
</body>
</html>
BEAN就放在
C:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\classes\test
，JB里到可以的
http://www.yesky.com/20020114/213945.shtml
C:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\jsp\beans\test
还是不行啊
:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\jsp\beans\test
不对!!是:
:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\classes\beans\test
sorry,上条写错.是把你的Jsp1Bean .class放到:
:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\classes\test\
jsp文件放在那？
把setProperty，getProperty
代码去掉直接调用其中的方法试试！我感觉你的setProperty不对
sample = newValue;
->
this.sample = newValue;
setProperty中的value要加上C:\JBuilder7\jakarta-tomcat-4.0.3\webapps\test\defaultroot\WEB-INF\classes\test
这个是对的
server.xml
<Context path="/test" docBase="test" debug="0"
       reloadable="true" crossContext="true">
现在连一般jsp都不行了

在输入class="test.时，JB能自动跳出jsp1bean.
可就是不行。
还是老样子。
去掉useBean就可以.
到底要如何设置啊
