EJB lookup on standalone tomcat to remote jboss

[skymic]

hi,

I have a WS endpoint deployed on a standalone tomcat V5.5.9 server.
The ws endpoint was generated from a wsdl file using jaxws (jwsdp2.0).

In this ws endpoint I try to lookup a session bean (EJB3.0) which is deployed on a remote JBoss V4.0.5 (on a different machine).

In my tomcat war I have all jaxws libraries which are needed for the ws endpoint plus jbossall_client.jar which is needed for the EJB lookup.
The libraires deployed are the following:
from jaxws:
activation.jar,jaxb-api.jar,jaxb-impl.jar,jaxb1-impl.jar,jaxws-api.jar,jaxws-rt.jar,jsr173_api.jar,jsr181-api.jar,jsr250-api.jar,resolver.jar,saaj-api.jar,saaj-impl.jar,sjsxp.jar
from Jboss:
jbossall-client.jar

When trying to do the lookup I get the following exception:
tomcat log:

java.lang.NoSuchMethodError: javax.xml.soap.MessageFactory.newInstance(Ljava/lang/String;)Ljavax/xml/soap/MessageFactory

and

SAAJ0537: Invalid Content-Type. Could be an error message instead of a SOAP message
Couldn't create SOAP message due to exception: com.sun.xml.messaging.saaj.SOAPExceptionImpl: Invalid Content-Type:text/html. Is this an error message instead of a SOAP response?

I think there is a collision with the javax.xml.soap.MessageFactory classes in the jaxws libs and jbossall-client.jar.

Are there any other jboss client libs which I can use in order to perform the EJB lookup?

Any help?

Thanks

Are you connecting to the remote session bean through a WebService?
But apart from that thing, the problem you have is that you're calling javax.xml.soap.MessageFactory.newInstance() passing a String value, and that method doesn't let you put any params...

Yes, I am trying to connect to a remote session bean through a web service endpoint.
But I am not calling the javax.xml.soap.MessageFactory explicitly. This is done in the code which was generated from jaxws2.0 (wsdl to java).

However I am a bit further now. I threw out the jbossall-client.jar and replaced it with jnp-client.jar and jboss-common-client.jar. Now the webservice can lookup the remote EJB but fails in the final PortableObject.narrow call.

Here's my lookup code:
String urlName = "jnp://localhost:1099";
Properties p = new Properties();
p.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL, urlName);
p.put(Context.URL_PKG_PREFIXES, "org.jnp.interfaces");

InitialContext ic = new InitialContext(p);

Object ref = ic.lookup("SDOCI/remote/SDOCIBusinessService");

SDOCIBusinessService busiService = (SDOCIBusinessService) PortableRemoteObject.narrow(ref, SDOCIBusinessService.class);

Here is the exception:

Does anyone know what I must do to lookup an remote EJB3.0 from a tomcat webapp?

Any help is appreciated.
