[jboss-user] [EJB 3.0] - Re: Permanent interceptor

[jc7442]

Hi,

I'm not sure you can simply add your own domain in the ejb3 interceptors. I just connect on existing one. 
If your need is to add your own domain check AOP documentation. From what I remenber it is explain but not so simple to implement.

It looks like that :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE aop PUBLIC
   "-//JBoss//DTD JBOSS AOP 1.0//EN"
   "http://www.jboss.org/aop/dtd/jboss-aop_1_0.dtd">


...
   

   <!--################################################### -->
   <!--My Interceptor-->
   
   
   <!--typedef name="bmx" expr="class(@javax.ejb.Remote) OR class(@javax.ejb.Local)"/-->
   
   <!-- FIN MyInterceptor-->
   <!-- ################################################### -->
 


   
     <!-- ################################################### -->
     <!-- My Interceptor-->
     
         <!--interceptor-ref name="fr.biomerieux.interceptor.ExecutionTimeInterceptor"/-->
         <interceptor-ref name="fr.biomerieux.interceptor.ExceptionHanlderInterceptor"/>
     
     <!-- FIN My Interceptor-->
     <!-- ################################################### -->

      
         <interceptor-ref name="org.jboss.ejb3.asynchronous.AsynchronousInterceptor"/>
...
   

   
      <!-- ################################################### -->
     <!-- My Interceptor-->
     
         <!--interceptor-ref name="fr.biomerieux.interceptor.ExecutionTimeInterceptor"/-->
         <interceptor-ref name="fr.biomerieux.interceptor.ExceptionHanlderInterceptor"/>
     
     <!-- FIN My Interceptor-->
     <!-- ################################################### -->
      
         <interceptor-ref name="org.jboss.ejb3.asynchronous.AsynchronousInterceptor"/>
...

And a intercptor:

public class ExecutionTimeInterceptor implements Interceptor {
  /**
   * Version number
   */
  private final Logger LOGGER = Logger.getLogger(ExecutionTimeInterceptor.class
      .getName());

  /**
   * Log the elapsed time of the execution of a method
   */
  public Object invoke(Invocation invocation) throws Throwable {
    long start = System.currentTimeMillis();
    try {
      return invocation.invokeNext();
    } finally {
      long end = System.currentTimeMillis();
      MethodInvocation methodInvocation = (MethodInvocation) invocation;
      Method m = methodInvocation.getMethod();
      LOGGER.fine(MessageFormat.format(MESSAGE.METHOD_EXECUTION,
          new Object[] { m.getDeclaringClass().getName(), m.getName(),
              ((end - start) / 1000.) }));
    }
  }

  /**
   * Return the name of the interceptor
   */
  public String getName() {
    return ExecutionTimeInterceptor.class.getName();
  }

}
