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

<?xml version="1.0"?>
 <ejb-jar xmlns="http://http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

 </env-entry>
 </session>
 </enterprise-beans>

 <assembly-descriptor>
 <interceptor-binding>
 <ejb-name>*</ejb-name>
 <interceptor-class>xxx.SampleLoggingContextInterceptor</interceptor-class>
 </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...

Hi.
I'm still stuck with the problem, descibed above...

Could anyone, please, point me to my mistake in the code, or at least say that it is not possible with the software I use....

I didn't found an opened bug or RFE in JIRA.

Thanks in advance

i'm experiencing the same problem in 4.0.5GA (RC9 of EJB3.0)

Actually, it works for me only if I specify in the ejb-jar.xml the injection target, as shown in the original message (I use @Resource annotation without any parameters though)

However, If I understand the spec correctly, it should work without specifying the <injection-target>, just env-entry name, type, and value. Also, as long as the name is the same as the interceptor's property in the java class, it should work with @Resource, no parameters.
