Yes, local interfaces.
Just that I'm using the interface name '...Local' when calling JNDI.
By the way, CXF is deployed standalone, I added the JARs in the repository. This may explain the issue.
However, my question is about servlets (the plain old servlets) and @EJB annotation. Could the injected EJB object (proxy) be undeployed?

If the war and ejb jar are in the same ear, you would not be able to stop the ejbs without the web app stopping first.

I'd need more details to understand what might be going on here.  If you are using POJO web services under the cxf that is installed in geronimo and looking the ejb up in java:comp/env.... then the two approaches should work identically.  I'm also assuming that the ejb is running in the same geronimo instance and you are using local interfaces (although this should not affect anything).

Hi all.
I had an issue with calling EJBs (stateless) from the web layer.
In the web layer I was using CXF and doing an explicit JNDI lookup to retrieve the stateless EJB instance (proxy, to be more precise). The issue was that those EJB references were retrieved only once when CXF services were started. After some heavy load on the server, at some point the EJB call failed with message:
Bean '...' was undeployed.
I assumed this is as designed and didn't try to fix it.
However, to avoid it I replaced CXF with plain old servlet and in the servlet class I used @EJB to inject the EJB instances. Everything works fine so far but I wanted to make sure I did the right thing. Is it possible that I run in the same issue with this approach? As I understand it, Geronimo will inject one instance in each servlet instance (and there will be only one servlet instance by default) - this is by the specs. Does Geronimo (OpenEJB) take care of circumstances when the EJB is 'undeployed'? Will it inject a fresh instance?
Thanks! Answers much appreciated.
