Hi,

I am trying to deploy a subset of a Spring 2.5.6 application on JBoss AS 7.1.1 (this application is currently running on JBoss 5.1.0 GA).

I have installed Snowdrop on JBoss as explained in the  http://docs.redhat.com/docs/en-US/JBoss_Web_Framework_Kit/1.1/html-single/Snowdrop_1.1_User_Guide/index.html manual.

The application is an EAR having the following structure :

app-root
     /lib
          ...
          cglib-2.1_3.jar
          ...
     /META-INF
          application.xml
          jboss-deployment-structure.xml
     
     module1.jar


The module1.jar contains the Spring application context definition files which are loaded by org.jboss.spring.vfs.context.VFSClassPathXmlApplicationContext.

After startup, Spring complains about a missing cglib library and raises an AopConfigException :

Caused by: org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

          at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:473) [spring-beans.jar:2.5.6.SEC02]


If I add the cglib library as a dependency of the org.springframework.spring:snowdrop module, then I get an IllegalArgumentException :

java.lang.IllegalArgumentException: class com.itesoft.share.persistence.iod.multitenant.TenantInterceptor$$EnhancerByCGLIB$$398b4762_3 is not an enhanced class

          ... 189 more


I don't understand why this is happening and I can't find much information about tyhe "not an enhanced class" exception.

I don't encounter these errors on JBoss 5.1.0 with the same Spring and CGLIB versions. 

Any help would be much appreciated.

Best regards,
Eric
