When I execute the following, i get:

prop.put(Context.PROVIDER_URL,"t3://localhost:7001" );
InitialContext ctx = new InitialContext(prop);
MyBeanRemote bean = (MyBeanRemote) ctx.lookup("ejb/MyBeanRemote");

Im sorry but I dont have an idea about whats wrong here. Have you tried looking for a solution on google ?

The reason it is returning this eror is that Weblogic is not identifying it as an j2EE app. There was a probelm with weblogic and BEA stated to create a new domain.

However, when I used the Managed Deployer from MyEclipse to deploy to a specific Web logic 10 domain, it states that it deployed successfully. When I login into the Weblogic admin console and select the domain and then Deployment, I do not see the J2EE app.

Therefore, I ceated a new project and deployed it manually, but it returns the following error:

Unable to access the selected application.
Exception in AppMerge flows' progression
Exception in AppMerge flows' progression
[J2EE:160120]Error: The module, 'EJBProjectTutorialEJB.jar', is declared either in the application.xml or in the weblogic-application.xml descriptor but cannot be found in the ear file

The application.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd">

<module id="myeclipse.1185394894765">
<ejb>EJBProjectTutorialEJB.jar</ejb>
</module>
</application>

Í believe im in the somewhat same boat here! .. if you figured a way around this, please let me know (i did manage to start my own thread on the subject before finding you ; http://www.myeclipseide.com/PNphpBB2-viewtopic-t-18307-highlight-ejb3.html )

You should :
1 - Declare the JNDI name on the ejb annotation :
@Stateless(name = "TestBean", mappedName = "TestBean")
public class TestBean implements Test {
...
2 - Use the following JNDI name :
"TestBean#com.ejb.sessions.Test"

Great, I had the very same problem and this solution worked just fine to me.
Nevertheless, I'd complete the explanation saying that TestBean is the implementation class and Test is the Remote Interface...

Any way, I didn't know this kind of JNDI pattern name. Is it only for WebLogic? I've reading the Oreilly EJB 3.0 (5th ed) and I have read nothing like that...

Thanks for the hint!

There is another solution for this. After doing Reverse engineering from the database to EJB3 components when you are writing EJB3 client, in your client class add a new member variable as "@EJB <yourRemoteClassName> <VariableName>;"

e.g.

@EJB MyHomeService home;

and in your test method do something like:

public void test()
{
home.findById(new Long(1));
}


With this approach you don't have to worry about creating and using InitialContext and doing lookup, Application server would take care of that.

That worked for me as well. However, I'm still trying to figure out what the name is for the default case (no "name", no "mappedName" attributes specified in the @Stateless annotation). A default "name" is not that important, but "mappedName" is said to be vendor-specific, so I'd rather avoid it.

The @EJB annotation only works if the client runs within the same container (or even the same EAR?).

I am trying to get a simple Stateless Session bean working on WebLogic 10 MP1 with Seam.

My HelloBean.java code is :

Code:

@Stateless @Name("hb") @JndiName("hb") public class HelloBean implements HelloBeanLocal { .....

I tried with/without

Code:

@JndiName("hb")

option.

Local Interface:

Code:

@Local public interface HelloBeanLocal {    public String sayHello();

And in my xhtml, I am trying to access this bean like this:

Code:

<h:outputText value="#{hb.sayHello}" />>

When I try to run this I get the following exception:

Code:

I had the same doubt. Searching in the console menus, I figured out a way to "see" how weblogic configures the EJB's names when you DON'T set the mappedName in annotations. Maybe it can help you.

It seems that weblogic combines the ear, jar, bean and interface names and register it on JNDI tree as a default EJB name.

to see the JNDI tree, go to the console, and there is a panel called "domain structure" on the left. Below this name there is a tree of menus where the root is the server instance name ( in my case wl_server ). Expand the "Environment" item below and click on "servers". The configured servers will be listed on central panel. In my case, there is only one, "examplesServer". Click on it. A link to "view the JNDI tree" will appear. Click on it and the EJBs names should be in the list.

regards...

Solved my problem. Thanks

prashantpharate,

Glad that it is solved.
Do let us know if you see any other issues.
