JSP:useBean-Problem

[feuerzangenbowle]

I have a problem with the using of the JSP-Tag
<jsp:useBean...>

I have made a simple application using JAAS.

If I use this code

<%@page contentType="text/html"%>

JSP Page



<form method="POST"
action='<%= response.encodeURL("j_security_check")%>'>
<%!
void check() throws InstantiationException, IllegalAccessException,ClassNotFoundException
{
}
%>



Username:



Password:





<INPUT type="button" value="PASS IS" onclick=""<%--'<%= jdbc.getOK()%>'>--%>








pack this code in a .war-File and deploy it in JBoss, it works. This dialog appears and I can make an input.

But if I insert the lines, here bold then
the server don`t find the file.

<%@page contentType="text/html"%>
<%@page import="databaseConnection.CurrentTimeBean"%>
<jsp:useBean id="time" scope="application" class="databaseConnection.CurrentTimeBean"/>
<%--<jsp:useBean id="jdbc" scope="request" class="databaseConnection.jdbc_test"/>--%>

JSP Page



<form method="POST"
action='<%= response.encodeURL("j_security_check")%>'>
<%!
void check() throws InstantiationException, IllegalAccessException,ClassNotFoundException
{
}
%>



Username:



Password:





<INPUT type="button" value="PASS IS" onclick=""<%--'<%= jdbc.getOK()%>'>--%>
<jsp:getProperty name="time" property="minutes"/>









Now my questions are:

Do I have to configure something in JBoss, so he understand the JSP-Tags?

Do I have to set any path?

Or what else can I do to make it runnable?

My development-environment is:

* j2sdk1.4.1_02
* jboss-3.2.1
* netbeans IDE 3.5


Many thanks for the help.

Could you also attach the exact error message you get in the server log and/or browser ?

ATTACHMENT

The package databaseConnection is in the war-File, which I deploy and in this package is CurrentTimeBean.java. I don`t understand what path is missing.

In NetBeans the compiling runs without errors. Only if I deploy the war-File the error occurs.

NOW I FOUND THE ERROR

You must take the Bean in the folder classes which is in the folder META-INF. Now the Application server find the bean and use it.
