Hello! Does your application contain dom4j jar file? If not, you should add it.
Usually, NoClassDefFoundError occures if some required jar is not present in the application.

Oh yes,I see. I added some libs and solved above problem. Now I have following libraries in my lib for hibernate

hibernate3.jar
antlr-2.7.6.jar
commons-collations-3.1.jar
dom4j-1.6.1.jar
javassist-3.9.0.GA.jar
jta-1.1.jar
slf4j-api1.5.8.jar

But when I run the app ,I see another error


and then I run again I got another error


Every first times after starting the server is first error and every second times is the last error. Why are the two errors different?
What will I do now? Do I need more libraries?

hibernate.cfg.xml and other hbm file you have kept in WEB-INF directory. You should need to place inside /WEB-INF/classes.

Try this one.

Yes I did. But I can't solve.
Actually, I think the problem is not with hibernate.cfg.xml file and .hbm.xml files. It might be because of lib files.
As for the first error, it said " java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder ".
When I take a look inside slf4j.jar, I don't see any such package "org/slf4j/impl/....". Something wrong?
This is how I write in my servlet
