Ok, this should have been relatively simple, but it hasn't been. I'm simply trying to get Log4J logging to work with Hibernate 2.0.3. The following describes my situation:

--Using Websphere Studio Developer 5.0
--Hibernate is being called from a Stateless Session Bean
--All library JAR files are packaged under the Utility JAR's folder (EAR root directory)
--This include log4j.jar and commons-logging.jar
--I tried placed the sample log4j.properties file everywhere at one point or other, but it never makes a difference (and have set it to debug)
--given that commons-logging.jar is found, having log4j.jar and log4j.properties there should work, but it doesn't.
-- there aren't any other log4j.properties laying around


I do see some logging in the console from Hibernate during configuration, but it only shows messages at the INFO level (and it only shows an 'I', not info.) I don't know where this formatting is coming from....

Any suggestions on what the problem could be would be greatly appreciated. It's very difficult to use the tool without adequate logging...

Thanks,
Brandon

basically, if i completely remove log4j.jar and log4j.properties from the project, it makes no difference anyway...so obviously they aren't being recognized.

The questions is, in an EAR file, where should they be located and how are they referenced?

Hibernate only calls commons-logging without any special settings. What you experience is the magic of broken Java classloaders and its interpretation by the Jakarta folks. Good luck :)

Apparently, Websphere implements its own specialized version of commons-logging (known as ws-commons-logging.jar)....


IT's not obvious nor easy to find, and it overrides anything you might do in your application....

I ripped it completely out and replaced it with commons-logging and log4j, and that did the trick...

who knows what the consequences will be.

That made my day :) Thank you :)

I have a pretty straight forward one-to-many relationship modeled, and I keep receiving the following error:

CMSProcessor::processAddition--Update Failed net.sf.hibernate.HibernateException: identifier of an instance of forecastingModel.Tunnel altered from 21 to 21

(where 19 is the generated sequence number).


In this scenario, I'm simply creating one new parent and one new child object, adding the child to the parents collection, and then calling session.save(parent).


Here's the segment from my log file, and the mappings for parent and child are below that.

Thanks for any help,
Brandon

oops, meant to post under a new topic...will move it.

thnx

They should be placed in the root of the ear file. Trick is, however, that you must then also modify the manifest file for the ejb jar files inside that ear to include a "manifest classpath" entry of '.'
