JBCS on Jboss 4.0.4GA

[enazareno]

Hi,

Has these questions been answered already? Our requirement is we need to run our applications on the same server as JBCS and our applications run in 4.0.4 version. I use JBCSM4. When I tried to merge it, I ran into different kinds of errors:

1. If you're using MySQL you cant use older versions of the mysql api driver. You need to upgrade to a higher version or the one that comes with the installer. Is it using driver-specific SQL statements or non-SQL92 statements?

2. Can JBCS run in boss-4.0.4.GA? I installed a fresh copy of JBoss 4.0.4GA and tried installing JBCS on it and it does not run. Does it run only in JBoss 4.0.3? We have AOP implementations and we were only able to successfully run it in JBAS4.04.

3. We also run JBPM and its using hibernate but not EJB3. Although there are no errors when we run it, but it was not thorough testing. Are there reported incidents that we need to be aware of?

Any suggestions? Should we upgrade to JBCS M5 (are these issues solved in that version?) Thanks.

Regards,

Elmo

Elmo,

I can't answer with 100% certainty, but I can try from my experience...

1) Yes, you need to use the MySQL driver from the install or newer - we're using mysql-connector-java-3.1.12-bin.jar without problems. The earlier driver we had been using broke stuff. ;-)

2) I think JBCS M4 installed version can't run on GA. I think even M5 installed version can't. I'm using a compliled version from CVS HEAD on GA and it works fine. Originally we used M5 on CR2.

3) I don't use jBPM, so can't help there.

In regard to upgrading... I'm pretty sure you'll have to blow away the db for M4 to use M5 as the data structures aren't compatible. So if you've got messages in the db you want, I guess you'll need to export them somehow... I think there was a post about this.

There are even some differences in M5 and HEAD on how the body ids work so older messages break - although I was able to fix this with a db script.

I'm hoping there aren't too many more changes to the data structures so I don't have to rework things when 1.0 comes out. ;-) That's the price you pay for early adoption I guess!

Hope that helps...

Oh yeah, Elmo, this question should probably have been posted in the JBCS User forum:

Not sure if you knew about that forum or not.

Hi,

So I guess this means its back to the drawing board then for us and figure out what components we need to drop.

No I'm not aware of this forum. Thanks. This helps a lot :).
