EJB2 beans and jndi ENC problems

[krot-s]

Hi everybody,

I'm trying to migrate old EJB2-based application from weblogic to jboss 7.1 and can't overcome problems with jndi-lookups.

I want to make beans available under names 'ejb/BeanName'. I mimicked one of unit-tests - https://github.com/jbossas/jboss-as/tree/master/testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/ejb/ejb2/reference/eararchive that does exactly what I need, but still get an error.

I have a bean OrdersBean that gets CustomersBean like that:

InitialContext context = new InitialContext();
Context env = (Context)context.lookup("java:/comp/env");
CustomersBean o = (CustomersBean)env.lookup("ejb/CustomersBean"); 

and  get an error:

javax.naming.NameNotFoundException: comp/env/ejb/CustomersBean -- service jboss.naming.context.java.comp.env.ejb.CustomersBean

My ejb-jar.xml is:

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                            http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"

                                        <home>com.pls.CustomersHome</home>
                                        <remote>com.pls.CustomersBean</remote>
                              </ejb-ref>
                    </session>
          </enterprise-beans>
</ejb-jar>

jboss-ejb3.jar is:

<?xml version="1.0"?>
<jboss:ejb-jar xmlns:jboss="http://www.jboss.com/xml/ns/javaee"
          xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          version="3.1" impl-version="2.0">
          <enterprise-beans>


                    <session>
                              <ejb-name>OrdersBean</ejb-name>
                              <ejb-ref>
                                        <ejb-ref-name>ejb/CustomersBean</ejb-ref-name>
                                        <jndi-name>java:module/CustomersBean!com.pls.CustomersBean</jndi-name>
                              </ejb-ref>
                    </session>
  
          </enterprise-beans>
</jboss:ejb-jar>

Application is deployed as single jar, and I still get an error:

javax.naming.NameNotFoundException: comp/env/ejb/CustomersBean -- service jboss.naming.context.java.comp.env.ejb.CustomersBean

What could causes the problem?

Thank you in advance.

oh, completely forgot to include jboss output during deployment:

        java:jboss/exported/myejbs/OrdersBean!com.pls.OrdersBean

Btw, jboss version is jboss 7.1 Final

[krot-s]

One more note: same example code works just fine under JBoss 6.1.0 Final, with one change in jboss-ejb3.xml - jndi-name changed from java:module/CustomersBean!com.pls.CustomersBean to java:/CustomersBean

How can I make this work under AS 7.1?

[jaikiran]

Context env = (Context)context.lookup("java:/comp/env");

Change this to:

Context env = (Context)context.lookup("java:comp/env");

Notice the difference?

[krot-s]

Yes! This worked, that you a lot!
