Class EJB3TCCLInterceptor

java.lang.Object
  org.jboss.ejb3.interceptor.EJB3TCCLInterceptor

All Implemented Interfaces:

org.jboss.aop.advice.Interceptor

public class EJB3TCCLInterceptor
extends java.lang.Object
implements org.jboss.aop.advice.Interceptor

EJB3TCCLInterceptor Interceptor responsible for setting the correct Thread context classloader (TCCL) during the EJB invocation. The EJBContainer's classloader is set as the TCCL for the duration of this invocation. The TCCL is then reset to the original classloader. Note: The TCCL switch happens from the point when this interceptor is invoked. So ideally, this interceptor should be the first in the chain of the AOP interceptors during the EJB invocation
