Using JBossCache on BEA WebLogic

[manik]

Hello all.

I've written a short HOWTO on using JBossCache (1.1) with BEA WebLogic (8.1), and I've even written a startup/shutdown class which runs the distributed cache as a service in WebLogic.

Pls see http://www.jboss.org/wiki/Wiki.jsp?page=JBossCacheAndWebLogic

Feedback is appeciated! :)

This is awesome. Do you mind if we move this under JBossCache wiki page?

BTW, any volunteer for Websphere HOWTO? :-)

Thanks!

By the way, it is linked from the JBossCache wiki page - see the last para on http://www.jboss.org/wiki/Wiki.jsp?page=JBossCache

I could try Websphere as well, but my experience/exposure to it is limited. Might be more efficient for someone skilled up in Websphere to give it a go. If no one has the time though, I could take it up ...

OK, chaps - I've looked at WebSphere 5.1, and there is no way to run startup classes. I spoke to a friend who has done a lot of work with WebSphere before, and he had to use a pretty messy kludge with a WAR file that gets deployed first, with a servlet with a static block that acts as a startup class.

Very ugly stuff.

Also, I did notice that WebSphere has something called a Dynamic Cache Service - I wonder if this is distributed, and whether this makes JBossCache on WS superfluous.

Has there been many requests for JBossCache on WS?

Not really; most people use WebLogic

I received the following error when running the examples given in http://www.jboss.org/wiki/Wiki.jsp?page=JBossCacheAndWebLogic

why having this error? Please help.

Looks like it is still using the DummyTransactionManager instead of Weblogic one.

Which version is this?

-Ben

[e2kcgan]

JBossCache is version 1.2.
Weblogic is version 8.1.

How do I change the transaction manager to weblogic one?

[ben.wang]

So do you GenericTransactionManagerLookup? If you do, I don't know what's the problem without looking into it.
