Question
I have a Java EE project packaged on an ear. The ear contains one Jar where i package my @stateless EJBs and other not managed classes (my model, utils etc). For some of these EJBs i use Jax-Ws to expose their functionality as a web-service.
I try to create a logging mechanism using AOP, so i place the @Interceptors annotation in my Jax-Ws powered EJBs. The problem is that when i try to compile/build/package using maven i receive the following exception. It seems the problem is specific to wsgen cause when i put the @Interceptors annotation in the NON Jax-ws annotated EJBs it compiles and runs without any problem. I use JAva build 1.6.0_41-b02.
I also tried to find an older version of javax.interceptor-api (probably compiled in Java 1.6, as major.minor version 51.0 means that it has been compiled in JSE 7, if i get it right) but seems that 1.2 is the older one.

No correct solution
OTHER TIPS
Are you try web-beans.xml instead annotation? if didn't please check this is link. May be the maven plugin don't recognize this annotation.
The class level declaration should be look like this code:
<myapp:MyWebServiceBean>
<myfwk:LoggingAopService/>
</myapp:MyWebServiceBean>
And this interceptor need to enabled:
<Interceptors>
<myfwk:LoggingAopService/>
</Interceptors>
I didn't test these codes.
web-beans.xml declaration you sent is jboss specific ? I use web logic and found that an interceptor can be enabled by the following xml added in the META-INF/beans.xml.
<interceptors>
<class>org.samples.LoggingInterceptor</class>
</interceptors>
I will try the xml declaration but because i was in a hurry i leveraged Handler capabilities provided natively by the Jax-Ws framework (using @HandlerChain annotation) to "intercept" web service requests and responses.
I also tried to create a new annotation using the @InterceptorBinding way:
@Inherited
@InterceptorBinding
@Retention(RUNTIME)
@Target({ METHOD, TYPE })
public @interface Logging {
}
@Interceptor
@Logging
public class LoggingInterceptor {
@AroundInvoke
public Object intercept(InvocationContext context) throws Exception {...}
@Logging
@WebService(serviceName = "MyWebService", portName = "MyWebService",
targetNamespace = "...")
@Stateless(name = "MyWebServiceBean", mappedName = "ejb/seb/MyWebServiceBean")
public class MyWebServiceBean implements MyWebService
{....}
but this does not compile too, i receive the same error:

Probably this is a case where ejb-jar.xml should be used
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
