javabean + jsp file + tomcat
Hello.

I'm using Tomcat 4.0.6
I'm new to javabean and trying to use it.

My jsp file looks like this

<%@include file="configuration.jsp"%>
<html>
<head>

</head>
<body>


<jsp:useBean id="searcher" class="Find" />

<jsp:setProperty name="searcher" property="indexName" value="indexLocation"/>

<li> The indexName is:
<jsp:getProperty name="searcher" property="indexName"/>

</body>
</html>
____________________________________________________
this is configuration.jsp

<%
String indexLocation = "C:/eclipse-SDK-2.0-win32/eclipse/workspace/Test/index";
%>
____________________________________________________
this is Find.java

import java.util.*;

import java.io.*;
import org.apache.lucene.analysis.*;
import org.apache.lucene.document.*;
import org.apache.lucene.index.*;
import org.apache.lucene.search.*;
import org.apache.lucene.queryParser.*;
import org.apache.lucene.demo.*;
import org.apache.lucene.demo.html.Entities;

import java.io.Serializable;

public class Find implements Serializable {

String indexName;

Find(){}

public void setIndexName(String name)
{
indexName = name;
}

public String getIndexName()
{
return indexName;
}
}
____________________________________________________
I get this error message

type Exception report

message Internal Server Error

And if I add this line
<%@ page import = "Find" %> in the jsp file i get this error

Class java.beans.Beans can not access a member of class Find with modifiers ""

I have also tried to put the Find.java in a package but that didn't help either

try this:
put your Find in a package, e.g. tool. and use

<jsp:useBean id="searcher" class="tools.Find" />

looks like your container doesn't like the default-package, and assumes org.apache.jsp as package.

i had a similar problem with a servlet.
