javax.naming.NameNotFoundException

[cleconte]

I am a beginner on JBoss and EJB.
I use Eclipse with Lomboz plugins to generate and deploy my EJB.
When I analyze server.log I find my EJB and all seem exact ( no warning)
But I don't see any log about JDNI name. When I test my EJB with my clientTest I have an javax.naming.NameNotFoundException: TestSession not bound on lookup method.
I think that the parameter of lookup method is bad, how can I find the correct value?

I have attached my ejb-jar.xml. in fact, I wonder if my bean is really bound with "TestSession" in JDNI.

Help me, please.
Christophe

Hi cleconte,

I think you have in the JBoss.xml this line: <ejb-name>TestSession</ejb-name>
and you have to in your client this lookup: ctx.lookup("TestSession");

You can check it with your browser: http://localhost:8080/jmx-console/
jboss --> service=JNDIView --> java.lang.String list()
this is the last option of this site: press the invoke -Button

You have to see
EjB Module: .jar
java:comp namespace of the <Namefrom JBoss.xml <ejb-name>TestSession</ejb-name> > bean:

You have to for your client lookup: ctx.lookup(" <Namefrom JBoss.xml <ejb-name>TestSession</ejb-name>");

I had the same problem Have a look to my posting.
You can copy and past the source code from the posting:

Hi Oli,

Now it's ok.

I have found my error. I have forgotten one .jar in my classpath.

I am very happy because it's my first EJB.

Thank you very for your help.
