[jboss-user] [EJB 3.0] - Question about injecting env-entry into interceptor

[mark.bramnik]

Hi
I'm a newbie in the JBOSS world and I've got a problem with env-entry declaration.
I have an ejb-jar.xml with declared interceptor for EJB3 SLSB.
I'm trying to inject the environment entry into the interceptor, and it doen't work.
It seems like jboss merely ignores this declaration- interception mechanism works fine but injection doesn't.
When I'm trying to inject the same env-entry declaration into SLSB bean everything works just fine.
As far as I understand xsd allows me to do such an injection into interceptor.

I'm using JBOSS 4.0.4 GA + EJB3-RC8 on Windows 2000 OS.

Any help is highly appreciated



Thanks in advance.

The relevant code looks like this:

ejb-jar.xml

  |    </interceptor-binding>
  |  </assembly-descriptor>
  | </ejb-jar>    
  | 
SLSB:
package xxx;
  | 
  | import javax.ejb.Stateless;
  | import javax.ejb.Local;
  | import javax.annotation.Resource;
  | 
  | @Stateless
  | @Local(SampleDataService.class)
  | public class SampleDataServiceEJB implements SampleDataService {
  |   @Resource(name="maxExceptions")
  |   private int maxExceptions;
  | 
  |   public int getMaxExceptions() {
  |     return maxExceptions;
  |   } 
  | 
  |   public void setMaxExceptions(int maxExceptions) {
  |     this.maxExceptions = maxExceptions;
  |   }
  | 
  |   public void sampleExecutionMethod() {
  |     //......
  |   }
  |    
  | }
  | 

The Interceptor


package xxx;
  | 
  | import javax.annotation.Resource;
  | import javax.interceptor.InvocationContext;
  | 
  | public class SampleLoggingContextInterceptor {
  |   @Resource(name="minExceptions") 
  |   private int minExceptions = 1;
  | 
  |   public int getMinExceptions() {
  |      return minExceptions;
  |   }
  | 
  |   public void setMinExceptions(int minExceptions) {
  |      this.minExceptions = minExceptions;
  |   }
  | 
  |   public Object interceptLog(InvocationContext inv) throws Exception {
  |     //......
  |   }
  | }

P.S. I copied the code above manually (not copy-pasted) so it may contain some insignificant syntax mistakes...
