Access Remote Session Bean from an separate web app

[kiyoharatakuya]

Hello Everyone!

I'm new here, and this is my first post, hope i get some help ..

I build a Remote EJB Session Bean :

@Stateless
public class MyEJB implements MyEJBRemote
{
public void sayHello(){ //implement ...
System.out.println("HELLO");
}
}

I deploy it on GlassFish 2 and want to access it from a servlet in an separate web application on another server.


the servlet looks like this...:
public class MyServlet extends HttpServlet
{
@EJB
MyEJBRemote bean;

public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
bean.sayHello();
}
}

and I deploy on tomcat server.

then I access the servlet, but the exception has thrown:

嚴重的: Allocate exception for servlet CallRemoteEJB
java.lang.IllegalAccessException: Class org.apache.catalina.core.StandardWrapper can not access a member of class com.kiyo.ejb.web.servlet.MyServlet with modifiers ""

It seems that there need some properties to specify the address of the server where the Session Bean is on, and I searched and found nothing but using InitialContext.lookup.

Can I access the remote Session Bean just using Annotation @EJB ?

Thanks very much

Problem Resolved.

[kiyoharatakuya]

add
%GLASSFISH_HOME%/lib/appsrv-rt.jar
%GLASSFISH_HOME%/lib/appsrv-deployment-client.jar
%GLASSFISH_HOME%/lib/appsrv-ext.jar
%GLASSFISH_HOME%/lib/appsrv-admin.jar
%GLASSFISH_HOME%/lib/appsrv-launch.jar
In /WEB-INF/lib and copy
%GLASSFISH_HOME%/lib/javaee.jar
into /TOMCAT_HOME/lib

then call the servlet again, it works!

But instead of using Dependency Injection, I tried and success using InitialContext

Hi kiyoharatakuya, I'm trying to do the same thing you did. Could you post your code using InitialContext ?

Thanks.
