I have an application using Hibernate to interface with a SQLServer database. This application has been running fine. But I have a new requirement to deploy parts of my application remotely, which requires me to sign my jar files.

Unfortunately signing my jar files seems to break Hibernate's use of CGLIB, as it generates proxy classes in the same package as the original class. But the original class is signed and the new proxy class is not, generating a java.lang.SecurityException.

I may be able to work around this by reorganising my packages and selectively signing only the jars that need to be deployed remotely (luckily all my Hibernate code will only run on the local server). But I would prefer not to have my project structure dictated by the CGLIB implementation, so if there is another solution I would appreciate the assistance.

Thanks
James

Isn't http://cglib.sourceforge.net/howto.html about this ?

you need to sign the cglib.jar and its output will be signed...

Thanks, that worked.
I had another look at the cglib howto, and now that I know what it is trying to say, I can see that it does in fact say this. But your explaination was a lot clearer.

Thanks
James

i have same kind of problem .i have changed the java.policy settings and
in other thread they asked me to update to cglib2.2beta1.jar file and i did both no progress ..it happens during only select query operation .

slect query is also very simple select * from salesDirector .

mail me :[email protected] ..its urgent .Appreciate your help

James_a_woods, how did you solve it? I have the same problem but I don't understand "max" response... My English is very poor, could you explain it to me? Thank you!
