Hi!
I know that there are responses on the list for this kind of
problem but there is no archive...yet.
I am new to JBoss after moving from Resin EE and I am trying to get
the hand of it - especially in the deployment area.
I have read a lot of tutorials based on ant (includind the official
doc) but I can`t make the entity bean bound.
I have been banging my head agains the wall for the last day and it`s
starting to hurt really bad so any help will be greatly appreciated.
Okay, before giving the details here is the behaviour:
the war is deployed okay and I can see the index.html page. The bean
classes are very simple - I have listed them at the end of the
message. The problem is that when I am accessing the jsp I cannot
get the entity bean reference:

Here`s is my configuration:
jboss-3.0.6 on RH 7.3
$ java -version
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
I have configured jboss with mysql using the samples xml and here
goes the application.
I have a very light entity bean that is being called by a jsp. The
directory structure is:
$ tree bs
bs
|-- META-INF
| |-- ejb-jar.xml
| `-- jbosscmp-jdbc.xml
|-- WEB-INF
| `-- web.xml
|-- index.html
|-- test
| |-- Handler.class
| |-- HandlerBean.class
| `-- HandlerHome.class
`-- test.jsp
3 directories, 8 files
I have symlinked the directory to
$JBOSS_HOME/server/default/deploy/bs.war
The sources are as follow:
#### test.jsp
<%@ page import="javax.ejb.*,javax.naming.*,test.*, java.util.*" %>
<html>
<%!
HandlerHome home;
public void jspInit()
{
try
{
// Get a naming context
InitialContext initial = new InitialContext();
getServletContext().log("Got context");
home = (HandlerHome) initial.lookup("HandlerBean");
getServletContext().log("Got reference");
}
catch (NamingException e)
{
getServletContext().log("Naming Exception
"+System.currentTimeMillis(),
e.fillInStackTrace());
}
}
%>
<%
%>
</html>

As you can see this jsp only get`s the context and then a reference to
the entity bean.
