There is an application being developed with hibernate in java. Its giving this exception when deployed on tomcat5

java.lang.ExceptionInInitializerError
java.lang.Class.initializeClass() (/usr/lib/libgcj.so.6.0.0)

The location of this exception is a program where there is a statement
sessionFactory = new Configuration().configure().buildSessionFactory();

or it might be
org.hibernate.Session s = (org.hibernate.Session) session.get();

please help with a solution

Are you using gcj? If yes than that's your problem. Sun do make a real JVM which works correctly.

the application is not using cgj files . its using cglib files.

the application is using
cglib, hibernate3, ant , dom4j elated jars.

And?

It has nothing to do with your jars, it's related to your JVM.

GCJ is GNU's attempt at replicating a perfectly good JVM in their own unique style.

exceptionininitializer will also be thrown if your configuration isn't working.

Check your hibernate.cfg.xml or however you configure hibernate and your database connection.

Please read the Javadoc for that exception. You are wrong.

All the javaDoc says is that it is thrown when trying to initialise a static variable. Often, that static variable is the SessionFactory since config is wrong.

But I admit in the general case, my previous post was not always right.
