Since updating to most recent version of Hibernate Tools and Eclipse Fall Europa, suddenly have situation where my application runs correctly but my JUnit tests fail with a Sax parsing error. I use a variant of the HibernateUtil static section to get a configuration; in the trace below, you can see that the configuration file is found, but a validating SAX XMLReader is apparently not found. But when I run the code in my application it runs fine. This test code previously ran without problems but something has obviously changed in my setup. This has sporadically been reported in this forum (code running in application but failing in tests) and the posters have indicated that they solved their problem, but their solutions have never been posted. Sorry that this is repeat issue apparently. Have been working on this for about ten days and out of ideas at this point. Thanks in advance for any suggestions.

Hibernate version:

3.2.5

Mapping documents:

Using annotations. Here is the hibernate.cfg.xml file:

Code:
<?xml version="1.0" encoding="UTF-8"?>

Code between sessionFactory.openSession() and session.close():

Not getting that far.

HI mdean77

Thanks. Tried to find jaxp.jar and information suggests this has been incorporated into other jars. Then looked at JAXB. But not sure what to do at this point.

Pertinent point that I completely forgot was that upgraded the Macintosh operating system to Leopard. Maybe this is a problem with that JVM.

Added the jaxb-impl.jar, jaxb-xjc.jar, and jaxb-api.jar from my jboss distribution, but no effect on the error. jasp.jar does not exist anywhere on my system.

Here is the .classpath file.

Code:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
   <classpathentry kind="src" path="src"/>
   <classpathentry kind="src" path="tests"/>
   <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
   <classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
   <classpathentry kind="con" path="org.eclipse.jdt.junit.JUNIT_CONTAINER/4"/>
   <classpathentry kind="con" path="DROOLS/Drools"/>
   <classpathentry kind="output" path="bin"/>
</classpath>


Inside the requiredPlugins referred to above, org.apache.xerces_2.8.0v200705301630.jar is included, and within this jar are accessible modules jaxp/*, jaxp/datatype/*, and jaxp/validation/* . There is also parsers/* in that jar.

Thanks.
