Cyclic dependency in EJB3 not resolved by JIRA EJBTHREE-792

[omerlin]

Hello,
We try to migrate a big glassfish application to jboss, but we have a blocking issue with cyclic depencies on EJB3.
The JIRA EJBTHREE-792 identified this issue as resolved thru the @IgnoreDependency annotation.
This is not so simple - this does not work for us at all.

I explain :

First at all it does not work at all for ejb-jar.xml deployment descriptor file.
There is no standard annotation IgnoreDepency even in jboss.xml, the jboss "not in spec" descriptor file.
We then try to move the ejb-jar.xml injection into the code directly with the @EJB annotations as indicated in EJBTHREE-792 .

It works for very simple code with @EJB injection without name references.
But if you add name parameters it does not work anymore. We need parameters to @EJB to specify implementation. (our Glassfish code use this)

You can try with this simple code :

Hello1Bean class:

@EJBs(
{ @EJB(name="ejb/Hello2", beanInterface=Hello2.class, beanName="Hello2Bean")

})

public @Stateless class Hello1Bean implements Hello1 {

@IgnoreDependency
@EJB(name="ejb/Hello2")
private Hello2 hello;

Hello2Bean Class :

@EJBs(
{@EJB(name="ejb/Hello1", beanInterface=Hello1.class,beanName="Hello1Bean")

})
public @Stateless class Hello2LocalBean implements Hello2Local {

@IgnoreDependency
@EJB(name="ejb/Hello1")
private Hello1 hello;

You then get the following dependency error :
--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3
State: NOTYETINSTALLED
I Depend On:
jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3
Depends On Me:
jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3

ObjectName: jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3
State: NOTYETINSTALLED
I Depend On:
jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3
Depends On Me:
jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3


We have the problem in both 4.2.2 & 5.0Beta3 versions.
We have currently no solution,no working workaround.

Need help,
thanks,
Olivier

Remove the class level @EJBs declaration. And let your beans look like this:

Hello1Bean class:

@Stateless
public class Hello1Bean implements Hello1 {

@IgnoreDependency
@EJB(name="ejb/Hello2")
private Hello2 hello;

}

Hello2Bean Class :

@Stateless
public class Hello2LocalBean implements Hello2Local {

@IgnoreDependency
@EJB(name="ejb/Hello1")
private Hello1 hello;

}

Whatever, you are trying to do with the @EJBs at the class level can be achieved by this change.

hi Olivier, i have posted the same problem here: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=136978

I will try this proposal, i hope that it will work !

this does not work when the interface has several implementations, in this case the following error is generated:

could not resolve global JNDI name for @EJB for container Hello1Bean : reference class: com.gemalto.session.Hello2Local ejbLink: duplicated in cyclic.jar


the question is: how to not use the declaration of reference with EJBs when the interface has several implementations?

Thank's

Please post the entire exception stacktrace. Also post the bean definitions(with annotations) that you are using (the interface and the multiple implementations).

I think i understand what you are saying. If you have multiple (bean) implementations for the same interface, you can inject the beans as follows:

Hello1Bean class:


@Stateless
public class Hello1Bean implements Hello1 {

@IgnoreDependency
@EJB(name="ejb/Hello2",beanName="Hello2Bean")
private Hello2 hello;

}


Hello2Bean Class :


@Stateless
public class Hello2LocalBean implements Hello2Local {

@IgnoreDependency
@EJB(name="ejb/Hello1",beanName="Hello1Bean")
private Hello1 hello;

}

Note, the use of beanName in the @EJB annotation at field level. If this still does not solve your problem, then post back with the details.

[nouredine13]

the bean definition that i'm using :

Hello1Bean class:


@Stateless
public class Hello1Bean implements Hello1 {

@IgnoreDependency
@EJB(name="ejb/Hello2Local")
private Hello2Local hello;

}


Hello2LocalBean Class :


@Stateless
public class Hello2LocalBean implements Hello2Local {

@IgnoreDependency
@EJB(name="ejb/Hello1")
private Hello1 hello;

}


Hello2Bean Class :


@Stateless
public class Hello2Bean implements Hello2Local {

@IgnoreDependency
@EJB(name="ejb/Hello1")
private Hello1 hello;

}

we say that the interface Hello2Local has two implementations : Hello2LocalBean and Hello2Bean, and in this case, the entire exception stackrace is :

I tried your suggestion, and I think it works quite well.

Thank you.
