ejb call exception

47 Views

Hi,

I deployed a bean managed entity bean on the WAS 6.40. I can lookup at the bean, call a find method that returns a collection of "Employee" objects. But when I try to call a method of that object I get a :

java.rmi.RemoteException: com.sap.engine.services.ejb.exceptions.BaseRemoteException: Transaction system failure in method de.saarstahl.was.beans.EmployeeObjectImpl10.getFirstName().

; nested exception is:

javax.transaction.RollbackException: com.sap.engine.services.ts.exceptions.BaseRollbackException: Transaction ( SAP J2EE Engine JTA Transaction : 0ffffff8d4bffffffae0007d ) marked for rollback.

Here is the client:

Employee emp;

try {

Properties p = new Properties();

p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");

p.put(Context.PROVIDER_URL, "pc1396:50004");

p.put(Context.SECURITY_PRINCIPAL, "Administrator");

p.put(Context.SECURITY_CREDENTIALS, "pass");

Context jndiCtx = new InitialContext(p);

Object ref =jndiCtx.lookup ("sap.com/DepBean/EmployeeBean");

EmployeeHome home = (EmployeeHome) javax.rmi.PortableRemoteObject.narrow(ref,EmployeeHome.class);

Collection c = home.findByName("becker");

Object o = c.iterator().next();

emp = (Employee)javax.rmi.PortableRemoteObject.narrow(o, Employee.class);

String a = em.getFirstName();

} catch (Exception e) {

e.printStackTrace();

}

I get the exception when I call the "getFirstName" method.

What is wrong with my code.

Best regards,

Werner
