 Post subject: Using Hibernate3.0 with Portal Bean Portlets on VAP7.2.1

Hibernate 3.0:

I am using hibernate with portal bean portlets on VAP (Vignette Application Portal 7.2.1). Following logs hibernate application is generating while initializing the hibernate session. This exception is not thrown with JSR-168 portlets.We have investigated the problem and found out that this problem is occuring due to different jars (jakarta logging and commons logging frameworks) used by VAP and hibernate respectively.

After seeing this message, I removed commons-logging jar file from the class path of hibernate and tried to use the same VAP jakarta-logging jar for hibernate also, but it then showed the exception that:

[i][b]Log4jImpl doesnot implement Log:[/b][/i]

After that I tried to remove jakarta-logging jar file from the VAP classpath and tried to use commons-logging jar for both (Hibernate as well as VAP).
But  then it showed diffrerent exception message that:

[i][b]NoClassDefFoundError: org.apache.commons.logging.LogFactory[/b][/i]

Please help now what should I do?
