Migrating Stateful Bean from EJB 2 to EJB 3 (org.jboss.invocation.CannotProceedException)

mbuamuh May 7, 2013 4:25 AM

See ejb3 stateful session bean attached. Migrating from ejb2 to ejb 3 requires me to use a home interface for my bean. But i am getting a blank CannotProceedException with no further explanations on what is causing it. Does anyone have an insight into this? Thank you.

How do you call it? remote or local.
Do you try a simple SFSB instead, i.e. from the ejb-remote quickstart?

Hi Wolf, It is local. My ejb has ejbcreate, ejbremove, ejbload and ejbstore methods implemented. Thus i am using a home interface which is different from the implementation in ejb-remote quickstart.

I'm puzzled
What you deploy? The SFSB as an EJB2 application? Or do you implement it as EJB3?
Could you attach an example?

You can't package EJB2 and EJB3 in one jar.

its a SFSB implemented as EJB3, migrated from EJB2. See my Bean java class attached.

This looks like you have migrated some CMP ejbFindXXX methods to an EJB3 SFSB.

I think if you just change all of those to findXXX methods and call them from a session bean reference (not the home reference) then it may resolve your problem.

As it looks like that it is something related to persistence I would recommend to use a SLSB and a JPA bean to migrate.
