I am using hibernate 3 and my application works well in my local machine. It is a linux machine. But when I create the jar file (with my classes) and use it from a windows machine (by using the Java Web Start), I obtain a set of error messages.

I read several messages with this type of error but none of them are solving the problem...

In my lib directory (in the linux machine) I put the following jars:

hibernate3.jar
cglib2.jar
commons-collection.jar
commons-digester.jar
commons-lang.jar

etc.


And the error is:

Thanks!

I could solve the problem!! I only put default-lazy="false" on each hbm.xml file in my application.

<hibernate-mapping default-lazy="false">

Thanks!!
