Re: Re: Re: Re: Deploying AXIS2 (1.5) on JOnAS 5.1.5

Guillaume,

thanks for your input.

Yes - finally our app is deployed and running on JOnAS 5.1 -- although
we had to do some workarounds to achieve this goal! 

-- we had to run off fastrmic  which makes building the .ear not very
comfortable
-- we had to re-structure some webservice-client classes to workaround
an obvious easy-beans classloader bug (the one with several nested
classes within a class)

As the app is running on JOnAS5 now, this is just the first milestone --
as it still is Java EE 1.4.  We now want to migrate all our SLSB's to
EJB3.

Will it be possible to make a step by step migration of the EJB's (so
have EJB2 and EJB3 "mixed" ?)


CMP EB's are already migrated to POJO's using hibernate (but not yet in
EJB-JPA context).


regards,
Hans
