Application module is not connected to a database

Question

Using JDev 11.1.1.3
I have an application that uses EJB and i have an application that uses business components. The EJB app needs to integrate some parts from the BC application so i package the BC model in a jar file and use it in my EJB to create some records.
This is some code that i execute in my EJB to create a new record using the BC jar:
ApplicationModule module = Configuration.createRootApplicationModule("bcApp.model.MyModuleImpl", "MyModuleLocal");
am = (MyModuleImpl)module;
BillDefImpl billDef = (BillDefImpl)BillImpl.getDefinitionObject();
bill = (BillImpl)billDef.createInstance2(am.getDBTransaction(), null);
//set some attributes
EntityDefImpl billLineDef = BillLineImpl.getDefinitionObject();
BillLineImpl billLine = (BillLineImpl)billLineDef.createInstance2(am.getDBTransaction(),null);
billLine.setBill(bill);
//set some attributes
am.getTransaction().commit();The weird behavior of this is that the first time i call this code, everything is working just fine. Both the bill and billLine are created in the database. No error shows up in the console.
When i try to do the exact same in the same session, i get the "Application module is not connected to a databas" error. When i open a new session, everything is working fine again.
I also tried using the am.getDBTransaction().commit(); instead of the getTransaction.
Can anybody tell me what could cause this kind of behavior? Am i doing something wrong?

Answer 1

Sorry, just a typo. I modified the classes/package for this post.
I also did some more testing and it appears to be EJB related. The code i provided above is called from an EJB. When I execute the code from a managed bean, i don't get this error when i execute it a second time.
Maybe also useful info. My application module uses a JNDI data source that is configured on the weblogic server.
