SOS-Creating WebService with Seam

[djohan0817]

Could someone please explain to me the steps that I have to follow to create a WebService and a WS Client with Seam, because I was following the Seam documentation, I put the file called standard-jaxws-endpoint-config.xml into the META-INF directory of the jar file that contains the web service classes, but still it doesn't work...

What do you mean by "does not work" - do you get exceptions or error messages of any sort? There was a fix put in yesterday resolving an NPE if no conversationId was specified on a WS call. I've been having trouble with sessions, but have been able to deploy and invoke the web service just fine:

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=114733

If you're using a stateless session bean (SLSB), then make sure you're using the @Remote (rather than @Local) annotation for your interface.

What version of Seam and JBoss are you using? I'm using the following:

JBossAS 4.2.0.GA
Seam 2.0.0.CVS31-07-2007
JBossWS 2.0.0.GA
JDK 6.0

Also be aware that there is extra config required to run WS under JDK 6.0.

Cheers,

Chris

Thanks Chris for your response. Well first of all, I must tell you that I've been using Seam for a few months but I've never done Web Services with it, so I'm kinda new to this stuff.

I'm using :
JBossAS 4.0.5.GA
JBoss Seam 1.1.6.GA
JDK 5.0

In order for you to help me, I'll explain what I've done. I have my project that I've been working on, now I have to add a web Service layer. So I added a new namespace in the project and I create a class and it's interface. Here is the content of my class (it's just a test):

import javax.jws.WebMethod;
import javax.jws.WebService;

 @WebService
 @Stateless
 public class WS_Test implements WS_TestLocal
 {
 private String message = new String("Hello, ");


 @WebMethod
 public String sayHello(String name) {
 return message + name + ".";
 }
}

I'm using Ant with eclipse to explode the project on JBoss. It generates the WSDL file, when I type "http://localhost:8080/jbossws" in the adress bar of my browser, I can see my web Service as a Registered Service Endpoint but when I click on it to view the wsdl, I get an error that tells me that the resource is not available. I don't understand...Any Idea?

Johan,

The name of your interface is WS_TestLocal which implies you are using the @Local annotation. For web services you need to use @Remote. For example, I think you should use something like this:

@Remote
public interface WS_TestRemote {
 String sayHello(String name);
}

Cheers,

Chris.

I had already replaced it when I saw your first response. Even though it's WS_TestLocal, I had the @Remote annotation inside.

In your logs do you see an entry something like this:

INFO [LifecycleHandlerImpl] WebService started: http://DFVGM71J:8080/dcs-dcs/DevelopmentAuthenticator

Where "http://DFVGM71J:8080/dcs-dcs/DevelopmentAuthenticator" is the published end point of my web service. To see the WSDL, add "?wsdl" to the URL:

http://DFVGM71J:8080/dcs-dcs/DevelopmentAuthenticator?wsdl

I have JBossWS 2.0.0, so your log entries may be different.

This is what I saw in my log:

17:41:55,187 INFO [EJBContainer] STARTED EJB: webServices.WS_Test ejbName: WS_Test
17:41:55,562 INFO [EJB3Deployer] Deployed: file:/C:/jboss-4.0.5.GA/server/default/deploy/malongo.ear/malongo.jar/
17:41:55,671 INFO [WSDLFilePublisher] WSDL published to: file:/C:/jboss-4.0.5.GA/server/default/data/wsdl/malongo.ear/malongo.jar/WS_TestService2213.wsdl
17:41:55,921 INFO [ServiceEndpointManager] WebService started: http://Johan:8080/malongo/WS_Test

When I add "?wsdl" at the end of "http://Johan:8080/malongo/WS_Test" in my browser, it gives me an error of type HTTP STATUS 404, telling me that the requested resource is not available.

I'm sorry Johan, but I'm all out of ideas :( Hopefully one of the Seam guys can help.

I suggest you head over to the JBossWS forum, as this isn't a Seam issue.
