Problem with Hibernate and jbossCache

[cmiranda]

Hello all,
I have a problem with my application , I use Hibernate 2.1.7c and jbosscache 1.1.1
My hibernate entities is not use cache ( in hbm files declaration ) , but when I do execute :
session.save ( pojo ) ;
I see in my log file , a put in tree cache .

Any idea ?

thanks.-

1) I'm using jboss-aop with some other application servers such as weblogic and websphere. Would this usage construe as a jboss license violation?? The basic stuff works with weblogic 8.1

Absolutely not as JBoss-AOP is distributed under LGPL. You can embed it anywhere. LGPL is only triggered when you modify JBoss-AOP code.

2) I'd like to jar load the interceptor classes at run-time and dynamically attach and detach interceptors to advice bindings.

I noticed that the AdviceBinding.addInterceptor(Class) takes only a "class argument". How can I ask the aspect manager to use a particular class-loader to resolve that class?

I tried the following from a session bean.

addNewInterceptor(classname) -> jar loads the class file using some jar-directory conventions and is able to render the interceptor class

attachInterceptor(pointcut,interceptor) -> does the following

AdviceBinding binding = new AdviceBinding(pointcut,null);
binding.addInterceptor(jarLoader.loadClass(interceptor));
aspectManager.addBinding(binding);

At the point of adding the binding I get the ClassNotFoundException initiated at the GenericInterceptorFactory. Oh! So do I provide a custom "JarLoadingInterceptorFactory" then? I'm going to try that out.

any comments/suggestions would be greatly appreciated

thanks

Ok, I've changed the code in CVS head to not create a GenericInterceptorFactory using the classname, but rather it can accept the java.lang.Class itself so this should solve the problem if you get from head.

You can get latest from CVS and build, or, in the meantime, the problem is that the GenericInterceptorFactory doesn't try and resolve the class until advice bind time. What you may be able to do is the following

Class interceptorClass = ....;
Thread.currentThread().setContextClassLoader(interceptorClass.getClassLoader);
AdviceBinding.addInterceptor(interceptorClass);
aspectManager.addBinding(binding);

Let me know if this helps.

Hmmn! I have no idea why. If secondary cache is not set, TreeCache should not be invoked.

Have you tried the Hibernate JBoss forum there?

Your xml file is garbled so it's difficult to tell. But make sure you have comment out the TreecacheProvider for the second level cache in Hibernate.
