convert Session EJB to web service

Are there any tools available to convert Session EJB, j2ee application to web service in Sun Application Server. I am looking for something similar to servicegen of weblogic.

I added @WebService to a session EJB and, rebuilt and redeployed the project and it converted my EJB into a Web service.
For the code given below:
-- cut here --
@Stateless
@WebService
public class HelloSessionBean implements server.HelloSessionLocal {
/** Creates a new instance of HelloSessionBean */
public HelloSessionBean() {
}
public String sayHello(String name) {
return "Hello " + name + " from session bean";
}
}
-- cut here --
the Web service endpoint was hosted at: http://localhost:8080/HelloSessionBeanService/HelloSessionBean?wsdl
webservices.xml is optional per JSR 109 MR2. JAXB provides 100% XML Schema support and allows serializing any Javabeans-style classes.
Is there something more to it ?

Yes, on the server side that's it.
Just be careful not to deploy a WAR module with a context root like the
one generated for your Web service endpoint below. GlassFish will let
you do it without warning, and your endpoint will become inaccessible to
your clients (HTTP Status 500 - WEB0502: No ad-hoc servlet configured to
process ad-hoc path), replaced by the new servlet app.

Very nice!
How about adding a link to a page (or writing one) how to write a client
that can access this bean through its endpoint?
BTW: when I undeployed the WAR that made my endpoint inaccessible it ran
again as before. I then deployed it again to show what happens to my
colleague and guess what? Both were accessible! Looks like RC3 might
have a quirk or two left.
#Shared context? I hope the person who designed that confirmed that that
has no bad consequences to servlet mapping or security settings in the
servlet module. It's late, I am not not going to try to figure it out.

Dies,
See in line ...

The nice thing about Web services is that the client and service are
completely independent of each other.
This Web service can be invoked using any of the mechanisms described at:

I have not experimented with this but do let me know what you find out.
Thanks,

I want to know something more. My problem is that I already have session beans so are there any conversion tools to convert these session beans to web services eligible beans.
I wanted to know about a tool that may append @WebService to my already existing beans to compile and convert them to be used for web services clients.

Correct |
|

Umm...
All you need to do (for basic functionality) is add @WebService to each bean, and then redeploy it. All of the work is done during the deployment by the container. There isn't really much to convert. And anything outside of the defaults would need to be specified directly within the Session Bean code anyway, there's really not much work for a tool (beyond a simple bulk handling script of somekind) to do here.

Yes this is a solution but I was just wondering why there is not something parallel to servicegen of weblogic in Sun Appserver
