Does Hibernate work on JDK 1.3? I tried to make it run but I can't. Is there anybody who could help me?

I tried to run the NetworkDemo example. Here is the output:

Thank you.

1.2.5 works fine on JDK 1.3.1_08. Regards

Hibernate is build with the latest stable JDK 1.4, this error may be a binary incompatibility with JDK 1.3. Recompile the hibernate.jar (ant jar) with JDK 1.3.

I also remembered this bug from old forum postings. It looks like this is a combination/issue with both Tomcat and the JDK. Here's the old thread:

http://sourceforge.net/forum/message.php?msg_id=2062040

I would appreciate if you can reproduce it and debug the problem for us. Please add your experiences either to the JIRA tracking system or the community area on the wiki at: http://www.hibernate.org/74.html (see the last entry).

Thank you :D

It works just fine after recompiling hibernate.jar using jdk 1.3.

Here is the Hibernate 3.1 recompiled with Java 1.3.
