EJB entity not BOUND

[pescouille]

Hello,

I have got a big problem,

when I launch my application Test, he said that my Engine is not bound.

What is the problem ?

my file TEST.java:

import java.util.Properties;
import javax.transaction.UserTransaction;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.rmi.PortableRemoteObject;
import engine.*;
import java.util.Hashtable;
import java.util.Properties;
import java.util.Collection;
import java.util.Iterator;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class Test extends HttpServlet{
/*public static void main(String args[]){*/
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
try{
/*Properties prop=new Properties();
prop.setProperty("java.naming.factory.initial", "");
prop.setProperty("java.naming.provider.url", "localhost:1099");*/
/* Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );*/

Context initialContext=new InitialContext();

out.println("");
out.println("");
out.println("Bonjour");
out.println("");
out.println("");


Object objref = initialContext.lookup("java:comp/env/Engine");

I have an Engine.jar in the deploy of Jboss

This file Engine is composed by three class: Engine, EngineHome and EngineEJB ( there are in a package engine)

The two files : ejb-jar.xml and jbosscmp-jdbc.xml seems to be good.

I really don't know my problem

Thank you for your help

If someone has a zip file with an EJB which runs, would he be possible to send me this zip to see what I'll have to do. ( with all the files to run this ejb )

thank you very much

[pescouille]

You can send me the zip at : [e-mail]

Thank you

Do you have a <ejb-ref> in your web.xml linking to the Engine EJB? Something like

<ejb-ref>
<ejb-ref-name>ejb/Engine>/ejb-ref-name>
....
....
<ejb-link>Link to Engine</ejb-link>
</ejb-ref>

Check the syntax, i mite be totally wrong on the descriptor tags.

Hi

you should try and use the JMX-Console and the JNDIView service to see where your bean is bound.

it should be somewhere under the global namespace if you are going to use it from a JSP page.

Use the name from JNDIView or change your deployment descriptors to place it in the correct place in the tree.

also it sould not be a local bean and you can set the JNDI name with a jboss.xml file.

Kind Regards

Thank you for your response but I don't have the lines that you cite in the jmx-console, I put engine.jar in the directory deploy of Jboss but He doesn't find Engine

[pescouille]

My file web.xml( extract) :

<ejb-ref>
<ejb-ref-name>local/engine</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
engine.EngineHome
engine.Engine
<ejb-link>Engine</ejb-link>
</ejb-ref>

My file is Engine.jar and it is situated in the directory deploy of Jboss

[pescouille]

My jboss.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS//EN" "http://www.jboss.org/j2ee/dtd/jboss.dtd">

<enterprise-beans>

<ejb-name>Engine</ejb-name>
<jndi-name>Engine</jndi-name>

</enterprise-beans>




My jboss-web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss-web PUBLIC "-//JBoss//DTD Web Application 2.3//EN" "http://www.jboss.org/j2ee/dtds/jboss-web_3_0.dtd">
<jboss-web>
<ejb-ref>
<ejb-ref-name>local/engine</ejb-ref-name>
<jndi-name>local/engine</jndi-name>
</ejb-ref>
</jboss-web>

[raja05]

Try
<ejb-link>Engine.jar#Engine</ejb-link>

instead of
<ejb-link>Engine</ejb-link>

Unpack your .jar file and make sure that your ejb-jar.xml and such are truly inside of the META-INF directory.

Hi,

Why do you have to repeat the ejb-name or jndi stuff in about 3 different places for webapps within the same .ear file?

I've studied the JBossNukes code and they don't have anything in the web.xml and neither does the JBossForum code. I doubt that they would use remote call to their ejbs.

Sorry for tagging this on the end of this chat but I started my investigation with exactly the same error and I'm frustrated to find you have to repeat configuration all over the place. (And xDoclet can't do it for me!)
