AFAIK geronimo 2.2 supports ejb 3.0, ejb 3.1 support is in progress
for geronimo 3.0. I know there are some features already implemented,
and I thought singletons were among the implemented features. However
you shouldn't expect full ejb 3.1 compliance from geronimo 2.2.
thanks

Please bear with me as this may be long. I am trying to be as
thorough as possible. I have upgraded my development environment
and projects to use Geronimo 2.2. I was able to successfully
replace the 2.1 server with the 2.2 server in my development
environment. Everything compiled and went smooth from that
standpoint (Good job guys). When trying to run unit tests from an
outside client, errors started to appear. This was to be expected
because I was still using the openejb-client-3.0.1 assembly. When I
updated the assembly to openejb-client-3.1.2, everything worked as
expected (once again, great job). By updating this, I was certain
that the Geronimo 2.2 tool was using the EJB 3.1 specification.
I then proceeded to try to use some of the new EJB 3.1 features.
More specifically, the Singleton. I changed one of the annotations
for my EJBs to Singleton and immediately got an error. I then
checked the classpath to make sure I was pointing to the correct
Geronimo installation. I was. In viewing the library assemblies in
my project, I did not see anything that looked like a EJB 3.1
assembly underneath the Apache Geronimo 2.2 library. The only
assembly that I found is titled: geronimo-ejb_3.0_spec-1.0.1.jar. I
went to that assembly and opened up the jar file. I did see
implementation classes for Stateful and Stateless but I did not see
one for Singleton as I had expected. I do not know if this is a GEP
issue or a Geronimo Server issue. In summary, it appears that the
running server is using EJB 3.1 but when referencing the library
during development time, it is only using the 3.0 specification.
Can someone help me out with this?
