EJB (SLSB) Injection Issues

[sendtopms.senthilkumar.peelikkampatti.bnsf.com]

Seam 2.0.1CR1 on Glassfish-V2ur2.
I have 2 SLSBs.

From Ejb1, I am injecting with @In(create=true) Ejb2 ejb2.
When I use JSP and InitialContext to access Ejb1, I got
org.jboss.seam.InstantiationException: Could not instantiate Seam component: ejb2. And further down the error stack I got below message,
Caused by: javax.naming.NameNotFoundException: No object bound to name java:comp/env/ejb/ejb2.

If I use @Ejb, it is working perfectly.

Please post some code and exception stack trace, otherwise it's hard to find the underlying problem!

It is simple to reproduce in Glassfish v2. Please have 2 dummy ejbs. Inject 2nd ejb into first one using @In.

Here is the code,

^{@Stateless
@Name("master")
public class MasterBean implements MasterLocal {
    @In(create=true)
/*    @EJB */
    SlaveLocal slave;
    public void checkDetails() {
        slave.asignedWork();
    }
}}

Local Interface

<sup>@Local
public interface MasterLocal {

    void checkDetails();
   
}</sup>

Here is the code for referenced (@In injected) Ejb,

<sup>@Stateless
@Name("slave")
public class SlaveBean implements SlaveLocal {

    public void asignedWork() {
        System.out.println("Asigned work called.");
    }

}



Here is the code for referenced (@In injected) Ejb,
@Local
public interface SlaveLocal {

    void asignedWork();
   
}</sup>

It is working with @EJB but not working with @In.

First a short reformat for better reading. Well can you post your configuration files for jndi binding in glassfish.

Thanks, I am aware of code formating...:)

Here is ejb local reference from web.xml

<ejb-local-ref>

        <ejb-ref-name>evolve/MasterBean/local</ejb-ref-name>

        <ejb-ref-type>Session</ejb-ref-type>

        <local>seam.test.ejb.MasterLocal</local>

        <ejb-link>MasterBean</ejb-link>

    </ejb-local-ref>

    <ejb-local-ref>

        <ejb-ref-name>evolve/SlaveBean/local</ejb-ref-name>

        <ejb-ref-type>Session</ejb-ref-type>

        <local>seam.test.ejb.SlaveLocal</local>

        <ejb-link>SlaveBean</ejb-link>

Here is the jsp which calls the ejb using InitialContext.

Well, now I understand. You try to get the first ejb by native lookup which tries to get another ejb through the seam container. Since you get the first through ejb container the seam container does not get involved correctly. Try to get the master bean by Component.getInstance(MasterBean.class). It should work.

[sendtopms.senthilkumar.peelikkampatti.bnsf.com]

Actually JNDI reference is my mistake as Seam Document says to Use either 

Component.getInstance()  or @In(create=true)

But the above code is still not working with JSP even after I use Component.getInstance() .
My code in JSP is as below as you told in your earlier post,

MasterLocal nr = (MasterLocal) Component.getInstance(MasterBean.class) ;

I got the below exception after the above change,

java.lang.IllegalStateException: No application context active
