I wrote 2 entity bean BMP(called A and B) that map 2 tables in DB.
I compiled, deployed and tested them. All worked fine.

After that I added a method in the entity A (bean and interface):
public void addB(String bvalue){
try{
Context initial = new InititalContext();
Object ref = initial.lookup("b");
BHome bhome = (BHome)PortableRemoteObject.narrow(ref,BHome.class);
bhome.create(bvalue);
}catch(Exception e){throw new EJBException(e.getMessage());}
}

Like above, I compiled, deployed and tested them. All continued worked fine, but each time I call the method "addB(bvalue)" by client...

void main (...
try{

...
String avalue = "avalue";
String bvalue = "bvalue";
Object ref = initial.lookup("a");
AHome ahome = (AHome)PortableRemoteObject.narrow(ref,AHome.class);
ARemote aremote = ahome.create(avalue);
aremote.addB(bvalue)
}catch(Exception e){throw new EJBException(e.getMessage());}
...

I obtain the following error:

2003-10-29 12:28:15,515 ERROR [org.jboss.ejb.BeanLock] removing bean lock and it has tx set! QPL bean=A id=it.eng.pattern.pk.GruppoPK@35 tx=TransactionImpl:XidImpl [FormatId=257, GlobalId=DELL0362//167, BranchQual=] synched=null timeout=5000 queue=[]

....

Instead If i don't call that method, all continue to works fine.
Help me to understand please.
