Is it possible to define a servlet filter for a stateless ejb webservice, on GlassFish 3.1

问题

I want to export a Web-Service which was implemented as a stateless EJB. I know that these WebServices were hanled by the EJB Container, when they are annotated as @Stateless + @Webservice. Is it possible to route all incoming requests to this Webservice through a Servlet-Filter.

The Servlet-Filter works when my Java-Class is annotated @Stateful and @Webservice, or just @Webservice. But not in conjunction with @Stateless. Anyway to register a Servlet Filter for an EJB Webservice?

Many thanks!

UPDATE: Solved this problem, by annotating WebService Class with

@WebService
@RequestScoped

Filter works only in this constellation and acting as Stateless class for WebService consumer.

回答1:

• Lifecycle Callbacks : You can have a method with @PostConstruct annotation which gets called after the container has initialized the bean.

• Interceptor : You can have a interceptor class which gets invoked when applied at bean class/method level by annotation @Interceptors(ProcessMonitor.class).

Note : I haven't tried it in conjunction with @Webservice.
