Re: Multiple instance of Beans created (Finder problem)

[Johan Eltes]

I’m not sure I completely follow your scenario, but in case the entity bean business method ends with a runtime exception (transformed to a RemoteException), the container will discard the bean instance, and therefore create a new upon the next invocation.   /Johan   -----Original Message----- From: A mailing list for Enterprise JavaBeans development [mailto:[EMAIL PROTECTED]]On Behalf Of Ashutosh Sent: den 10 september 2001 19:20 To: [EMAIL PROTECTED] Subject: Multiple instance of Beans created (Finder problem)   hi everyone,                                                                                                                                                   We have 3 beans , 2 of them are Stateless Session Beans and the third is   a Entity bean (using Bean managed persistence). All method in the Entity   bean run in Supports txn scope.                                                                                                                       The SSB 1 has a method in Required Txn scope in the Remote Interface       which looks for a specific row in the db using the Entity Beans            findByPrimary key method.                                                                                                                             The SSB 1 then calls a biz. method on the entity bean. It then passes on   the primary key atrributes to the SSB 2 method ( Required Txn scope again  ) which does a findByPrimary key on the Entity Beans ( basically looks up  for the same row ) and calls a biz method in the Entity Bean.                                                                                         The problem we are facing is,                                                                                                                         When SSB2 calls the findByPrimaryKey method on the Entity bean a new Bean  instance is created ( the constructor of the Bean is called ) and the      subsequent call to the biz method does not call the ejbLoad ( as it is     running in Required Txn scope. ) and as the attributes of the bean are     populated in the ejbLoad the biz method execution fails.   Since, we are refering to the same row in the table our understanding is that another instance need not be created.However, the call to the constructor defies our inderstanding.                                                                             We understand that passing the reference of the entity bean to the from SSB1 to SSB2 would solve our problem. But, the behaviour exhibited confuses us.   FYI, we are running EJB1.1 on Weblogic 5.1 with SP9. Any pointers on the problem will be highly appreciated.                                 Thanks, Ashutosh.
