Hi,

The case:
I am using hibernate 2.1 against informix 9.x on a SunONE 7 application server. When I try to enable the logging I put the log4j.jar and the log4j.properties (from hibernate) in to my classpath. (I do this by putting both of them in the root of my ear and having the log4j.jar in the MANIFEST of my ejb.jar).

the problem:
when i run the application i get following exception:

I tried to remove the log4j.jar then i get no exception but hibernate then does not use the log4j.properties file. I also tried some other ways to put them in my classpath, always with the same error.


Does anyone have a clue ! I am looking at this problem for while now and i am not sure if this is a hibernate vs sunONE problem.

All these remote exceptions are not very helpful ... try finding the real exception, your server should log it somewhere in the server logs I suppose. Most likely the problem are different conflicting log4j jars I suppose

The code works fine when I remove log4j.jar from my classpath. Yet, hibernate does not use log4j then for logging purposes. there is only 1 log4j.jar in the classpath, serverpath, ... so with wat can it conflict.

Try to play with commons-logging.proeprties to switch between JDK log and log4j log.
Be sure log4j.properties is really read by log4j (If I remember weel, it's logged when failing).

This file must not be in any /lib directory.

It must be in your application classpath. Hibernate use common logging to log. Commons logging delegate the work to either JDK 1.4 or log4j.
you can find more (and better) information in the commons-logging doc http://jakarta.apache.org/commons/logging.html

I tried to set the commons-logging.properties diferrent ways in my classpath. When I deploy everything under Websphere and configure hibernate logging as described in the manual -> IT WORKS FINE.

If I do exactly the same on SunONE 7 I still get the exception which is not very good in explaining the real problem -;). So I guess my new questions should be :

Does anyone ever tried to configure log4j logging for hibernate on SunONE 7 ?
