Exposing EJB method as REST service

2019-03-29 05:39发布

问题:

In J2EE 6 you can expose your EJB session bean as a REST web service as below

@Stateless
@Path("/test")
public class TestSessionBean {
  @GET
  @Produces("application/xml")
  public String getTest() {
    return "<?xml version='1.0' encoding='UTF-8'?><val>test session bean</val>";
  }
}

This works when I packaged the EJB in the .war, however, when I try to package my project into separate web and ejb modules inside an EAR I get an HTML 404 not found error.

Can someone please explain?

I'm using Glassfish v3

Here is my web.xml

<servlet>
    <servlet-name>TaskRestService</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
  <load-on-startup>1</load-on-startup>


</servlet>
<servlet-mapping>
  <servlet-name>TaskRestService</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>

回答1:

JAX-RS annotated enterprise beans in a stand-alone or in a separate ejb-jar file that is included in an EAR is not supported.
