Hibernate: Re-Deploy destroys WebService

[Former Member]

Hi all,

I'm working with NetWeaver 2004s and Hibernate 3. I've developped a stateless SessionBean wrapped by a WebService. One of its business methods performs a Hibernate-HQL-query.

Testing the business method works fine as long as I do not re-deploy the application. Re-Deploy of the application causes an error at next call of the business method. This is even true if I do not modify anything in my source.

After re-starting the whole NetWeaver, everything works fine again.

Deleting the application and the WebService before re-deployment does not help.

Does anybody have an idea what I'm doing wrong?

The error message when calling the business method is:

Caused by: org.hibernate.HibernateException: org.hibernate.PropertyAccessException: exception getting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of com.karmann.applman.hibernate.ConfigValueHelperPK.?

Hi Christoph,

This seems like a classloading issue. Please make sure that you also redeploy all other components that your application depends on. (If you have specified those dependencies in the application-j2ee-engine.xml this should happen automatically.)

HTH!
