Okay, here's a newbie's first forum question (after searching forum, Google, etc.). Using Hibernate in Windows XP Eclipse with current PostgreSQL on a very simple set of tables. Works great in Eclipse--JRun green bar, proper data management, etc. No problems.

Now I'm building an Ant script to run a test coverage job using coburtura and JUnit. Searches have uncovered the fact that coburtura and Hibernate use different versions of asm.jar. Coburtura needs the asm-2.2.1.jar file it ships with in the Ant classpath for the instrumentation task, and Hibernate needs the asm.jar file it ships with in the application classpath. Don't know if this is the problem or not, but it could be relevant.

Hibernate version: hibernate3.jar in Eclipse (don't know how to get specific version ID)

Code between sessionFactory.openSession() and session.close(): Not getting that far.

Name and version of the database you are using: Current version of PostgreSQL, 8.1-405 I believe

The generated SQL (show_sql=true): Not applicable

Debug level Hibernate log excerpt: Not sure where that is in Eclipse.

Here is the Ant file I am using. All jars needed by Ant itself are set in a classpath option of the External Tools dialog classpath tab, and include: ant-junit.jar, asm-2.2.1.jar, asm.jar, cobertura.jar, commons-collections-2.1.1.jar, commons-logging-1.0.4.jar, dom4j-1.6.1.jar, hibernate2.jar, jakarta-oro-2.0.8.jar, junit.jar, log4j-1.2.9.jar, log4j.jar, and 3 PostgreSQL JDBC jars.

Note that this script is still under construction and prettyrough. Still everyting is now working except Hibernate.

Thanks in advance for any help anyone can offer.

Has this gotten lost in the mists of Forum time, or have I happened across something that is quite out of the ordinary?
