Tried to use RepositorySelector on MDB

on my MDB i put this

public void setMessageDrivenContext(MessageDrivenContext _context)throws EJBException {
 context = _context;

 //initialized my own RepositorySelector class
 MyBeanRepositorySelector.init(context);

 log = Logger.getLogger(CrmIntergatorBean.class);


 // For debugging purposes
 log(Priority.DEBUG, "CrmIntergatorBean.setMessageDrivenContext()");

 }

and created a class file

 if (repository == null) {

 }
 }

}

I also added log4j.xml on package to META-INF, When i deployed and test the code i got this error
