new jboss related files found at new 2.1rc1 lib

dear all,

could Hibernate tell the user whether the jboss related files are necessary to copy into jboss lib folder whenever one needs to employ mbeans jmx sar files or perhaps the existence meant to server othe specific objectives?

thanks

The jboss-xxx jars are only for people not using JBoss who want to use TreeCache.

Dear Gavin

Thanks a lot, with new 2.1 rc1 , any new additional library need to be copy to the jboss lib in order for it to function or not , it seems that ehcache is required now.

Just one more query , do j2ee.jar is a must if one wish to employ standalone hibernate ?

If so, please state in the reference manual to help those beginners.

Just a suggestion only, I hope is ok with you.

ehcache is required if you use it as second cache level

The treecache.xml sample bundled with 2.1rc depends on MBean including naming, transaction etc..,and dressed itself as MBean too.

Is there any configuration we can use which doesn't contain MBean requirement for the folks not using app-server?

you don't need an actual running MBean server to use the same treecache.xml. It should Just Work.

I documented the Hibernate 2.1/JBoss configuration in http://www.hibernate.org/66.html. Check it out, and if you learn anymore, please update the wiki page.

Thanks,

Sherman

Thanks Gavin, I just gave it a try. After fix some loose ends, I made it up running. The parts missing in RC1 are jboss-common.jar and log4j since TreeCache use JBoss logger and in turn uses log4j. Anotherthing change is in treecache.xml, change the cachemode to literal string instead of number since the treecache jar rc1 bundled does conversion itself.

Now the hard part, I got the following exception:

Code:

TreeCache is a full transactional cache: ...
   at net.sf.hibernate.cache.TreeCache.unlock(TreeCache.java:102)
   at net.sf.hibernate.cache.ReadWriteCache.get(ReadWriteCache.java:92)
   at net.sf.hibernate.impl.SessionImpl.doLoad(SessionImpl.java:2030)
   at net.sf.hibernate.impl.SessionImpl.immediateLoad(SessionImpl.java:1857)
   at net.sf.hibernate.proxy.LazyInitializer.initialize(LazyInitializer.java:49)
   at net.sf.hibernate.proxy.LazyInitializer.initializeWrapExceptions(LazyInitializer.java:56)
   at net.sf.hibernate.proxy.LazyInitializer.getImplementation(LazyInitializer.java:156)
   at net.sf.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:72)
   at net.sf.hibernate.proxy.HibernateProxy$$EnhancerByCGLIB$$7cbe25aa.getFactory(<generated>)
...

I don't use tx for query operation at all, but in this case it seems transaction is mandatory. What should I do instead of creating transaction?

You could try using org.jboss.cache.transaction.DummyTransactionManager ... see http://www.jboss.org/developers/project ... orial.html, under "CacheAop with Transactions" - don't know how this works out however

yeah, we probably should start bundling log4j.jar with Hibernate (grumble)

Yes, this was a change in TreeCache since I added the example config file. Will fix.

Well, not you are requiring it, JBoss-cache need it since the first import it has is 'import org.jboss.logger...' so it is required.

I like the 'grumble' on log4j :-)

Yeah, transactional does the trick.

Any performance degrade if I use transactional cache compare to read-write cache? Okay, okay, I know I have to benchmark it but doesn't hurt to ask since my application has intensive read vs. mild write activities.

I am getting that from jboss-jmx.jar
