Websphere to Geronimo

Greetings.

I got to see your ApacheCon presentation - J2EE Application Development on
Apache Geronimo Simplified using Eclipse.

May I ask:
I am currently using Rational Software Architect v6.0.1.2
Are there any available plugin for RSA that can support Apache Geronimo for
easier deployment?

Also, do you know of any howto of converting EAR files.
I have an EAR file deployed using the WebSphere v6.0 runtime
and I would want it to run using Apache Geronimo. or wouldn't it be
possible?

Your response will be very much appreciated.
Thank you very much.

- James

Well, you can install RAD 7.5 atop Eclipse IDE you've got installed
elsewhere. It might be easier than we think to have RAD 7.5+Eclipse
IDE 3.3.2+GEP 2.1.1 bundled together. Anyone fancy trying it out?

The biggest problem, is the level of WTP used by Rational.
RAD/RSA 7.0 uses Eclispe 3.2 and WTP 1.5.
RAD/RSA 7.5 uses Eclipse 3.3 and WTP 2.0, which is the Eclipse levels 
GEP 2.1.1 was tested against.  I think Tim tried running GEP 2.1.1 on 
RAD 7.5, but ran into a missing Console prereq....  you'd have to see if 
he has more info.

As far as deploying a WAS EAR onto Geronimo, you would have to manually 
migrate the WAS deployment descriptors and binding data into Geronimo 
deployment plans, as I haven't seen a tool or tutorial on how to do this....

There is a tool available to help going the other way, migrating from
Geronimo to WAS.  See
http://www.ibm.com/developerworks/websphere/library/techarticles/0804_stelzer/0804_stelzer.html.
Jacek is right, you'd have to manually port the EAR to Geronimo, and
add the appropriate Geronimo-specific deployment plans.  GEP can help.
 After you port your EAR to Geronimo, you should be able to keep both
the WAS- and Geronimo-specific deployment plans in the EAR so that it
may be deployed on WAS or Geronimo.

Hi James,

(This is sort of a question for the geronimo user mailing list and we
shouldn't be answering such here, but...it's the last time, deal?)

AFAIK, RSA 6.0 is based on Eclipse 3.0 so although it was not tested
GEP should work fine I believe. Give it a shot and report to the
geronimo *user* mailing list.

I don't think so. I'm sure it would not be an automatic process and
would require some manual changes. OpenEJB which is the EJB container
for Apache Geronimo doesn't understand websphere-specific deployment
descriptors so if your application relies on them, it won't work in
Geronimo (at least as far as EJBs are concerned). It's being worked
out though. Other non-EJB-websphere-specific descriptors are not
recognized by Geronimo either. It shouldn't be a problem to do the
resource mapping again. Could you share more information on the
structure of your application? What modules are there? What's their
descriptors and such. Use the geronimo *user* mailing list.
