Remote Client to EJB 3.0 fail .. :( javax.naming.Communicati

[j0ke]

Hello i have want to try EJB 3.0 but i have problems.
the problem is this i have EJB 3.0 like this :
package beans;

import javax.ejb.Stateless;

@Stateless(name="SimpleSession")
public class SimpleSessionBean implements SimpleSession {
public SimpleSessionBean() {
}

public String sayHello(String name) {
return "Hello "+name;
}
}

package beans;

import javax.ejb.Remote;

@Remote
public interface SimpleSession {
public String sayHello(String name) ;
}


and i make test client for it .

package client;

import beans.SimpleSession;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class SimpleSessionClient {
public static void main(String[] args) {
InitialContext ctx;
try {


ctx = new InitialContext();
ctx.addToEnvironment("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
ctx.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
ctx.addToEnvironment(Context.PROVIDER_URL,"jnp://localhost:1099");
SimpleSession simpleSession
= (SimpleSession) ctx.lookup(SimpleSession.class.getName());
System.out.println(simpleSession.sayHello("EJB3"));
} catch (NamingException e) {
e.printStackTrace();
}
}
}


but when i delpoy the EJB and start the client i get :
cannot find : org.jboss.naming:org.jnp.interfaces
Nothink UNNORAML
i add to the CLASSPATH everythink in jbossServer/client/*.jars
when i start now i get :


log4j:WARN No appenders could be found for logger (org.jnp.interfaces.NamingContext).

i try with just "localhost" and "jnp://localhost" but then the problem is the same.

Did you, by any chance, change the JNDI port?

What operating system are you running on? Are you running a firewall and have your configured it properly?

[j0ke]

Windows XP SP2.
No Firewall its off.
JBoss 4.0.4 and 4.0.3 result is the same
ejb3 enabled
when i install FULL (ALL) installation of JBOss 4.0.4 EJB 2.1 works fine EJB 3.0 dont deploy i think that it search for descriptors then and the error then is no bound "EJbName" .
But with ejb3 enable and EJB the problem is this i test it on 2 pc's result is the same am i wrong somewhere ?
How can i change this port ?

[j0ke]

another strange problem
when i deploy EJB3 with ejb3 enabled ( i mean installed jbos from installer.jar and check the EJB3 support ) . So.. when i open web-console i and go to ear of the EJB and click on it nothink happened .. i cant see the EJB name like when it is EJB 2.1 i cant see how match instances are created and etc.

[peterj]

Looking at the original post again, I see that you have a standalone client app from which you are attempting to look up the EJB. When you run that client app, are you providing the necessary jar files in the classpath? I thought I had a script file that ran an EJB3 client, but I cannot seem to find it (it's probably at home on my laptop). As a guess, include jbossall-client.jar, jboss-ejb3-client.jar and jboss-ejb3x.jar, all from the client directory, in your client's classpath.

Also, look at the EJB3Trail: http://trailblazer.demo.jboss.com/EJB3Trail/

[j0ke]

i have included all the jboss\client jars to my classpath
becouse if i dont include them at that line :
ctx.addToEnvironment("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
it throws error cant find org.jboss.naming .. .etc.
btw i have installed JBoss AGAIN 4.0.4- PATCH 1.
now my web consoile dont work
but when i deploy the same EJB and run the SAME client i get :
javax.naming.NameNotFoundException: beans.SimpleSession not bound
witch is step forward but i dont know why the EJB is not delpoyed how can i check what EJBs are deployed and what not ?

[j0ke]

the code is the same :
public static void main(String[] args) {

InitialContext ctx;
try {

ctx = new InitialContext();
ctx.addToEnvironment("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
ctx.addToEnvironment("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
ctx.addToEnvironment(Context.PROVIDER_URL, "jnp://localhost:1099");
SimpleSession simpleSession =
(SimpleSession)ctx.lookup(SimpleSession.class.getName());
System.out.println(simpleSession.sayHello("EJB3"));
} catch (NamingException e) {
e.printStackTrace();
}

I delpoy EAR file with EJB is there a chance JBOSS to expect (need) JAR instead of EAR ?

[peterj]

Deploying an ear file is fine, that is how I usually deploy my ejbs. What are the contents of your ear file? Run "jar tf ear-file-name" and post the results. If the ear file contains a jar file (or a war file), repeat the "jar tf" for those files (you will have to unpack the ear first).

You can see what EJBs are deployed by looking at the console output., You should see something like this:

13:13:06,866 INFO [Ejb3Deployment] EJB3 deployment time took: 31
13:13:06,882 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=calc2-ejb-1.0.jar,name=StatefulCalculator,service=EJB3 with dependencies:
13:13:06,913 INFO [EJBContainer] STARTED EJB: peter.ejb3.calc2.StatefulCalculator ejbName: StatefulCalculator
13:13:06,960 INFO [EJB3Deployer] Deployed: file:/D:/apps/jboss-4.0.4.GA-src/build/output/jboss-4.0.4.GA-ejb3/server/default/deploy/calc2-ejb-1.0.jar

Using jmx-console, and using JNDIView mbean to look at the global namespace, I see:

+- StatefulCalculator (class: org.jnp.interfaces.NamingContext)
 | +- remote (class: java.lang.Object)
 | +- remoteStatefulProxyFactory (proxy: $Proxy71 implements interface org.jboss.ejb3.ProxyFactory)

lol SOMETHINK STRANGE
in JMX console
i see SimpleSessionBean but in j2ee apps :
jboss.j2ee
ear=SimpleSessionBean.ear,jar=SimpleSessionBean.jar,name=SimpleSession,service=EJB3
module=SimpleSessionBean.jar,service=EJB3

[j0ke]

yep and the problem comes from application.xml..
witch JDeveloper is generate
<?xml version = '1.0' encoding = 'windows-1251'?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee">
<display-name>SimpleSessionBean</display-name>

SimpleSessionBean.jar



what must be contained in the ear fail with jar fail ? for EJB 3.0 ear.

[j0ke]

yes and the problem comes from application.xml fail it contains :
<?xml version = '1.0' encoding = 'windows-1251'?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee">
<display-name>SimpleSessionBean</display-name>

SimpleSessionBean.jar



what i must put in the ear file for EJB 3.0 EAR. ?

[peterj]

The entry you found in the jmx-console was not for the EJB, but rather for the mbean that was automatically created for the EJB. To look at the JNDI namespace, in the jmx-console, click on the service=JNDIView entry under the jboss namespace, then click on the Invoke button under the list() operation.

According to the console output, you should use the name "SimpleSession" to look up the EJB.

[j0ke]

I am at work and i have created new EJB
and deloy it its 1:1 with beffore and JBoss version here is 4.0.4- patch 1
The EJB is
@Stateless(name="SimpleEJB")
public class SimpleEJBBean implements SimpleEJB {
public SimpleEJBBean() {
}
public String sayHello(String name) {
return "Hello "+name;
}
}
the EAR is the same with application.xml in it.
and the JNDIView says this :
listXML() invoke :
4.0.3 EJB 3 deploy
org.jnp.interfaces.NamingContext

SimpleEJB
org.jnp.interfaces.NamingContext

remote
$Proxy65


but in my test client
public class TestClient {
public static void main(String [] args) {
try {
final Context context = getInitialContext();
SimpleEJB sessEJBTest = (SimpleEJB)context.lookup("SimpleEJB");

sessEJBTest.sayHello("exxx");
} catch (Exception ex) {
ex.printStackTrace();
}
}

private static Context getInitialContext() throws NamingException {
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");

environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
return new InitialContext(environment);
}

}
result is the same :
javax.naming.NameNotFoundException: SimpleEJB not bound
at org.jnp.server.NamingServer.getBinding(NamingServer.java:529)
at org.jnp.server.NamingServer.getBinding(NamingServer.java:537)
at org.jnp.server.NamingServer.getObject(NamingServer.java:543)

[j0ke]

how can i scan all contexts for the bean is there a subcontext or somehtink :(
help pls.
PeterJ your the only hope :)
