Expose ejb3 as jaxws web service

Question

Dear,
I want to expose my ejb3 stateless sessionbean as a jaxws web service (in order to have versioning for production redeployment high availability). I followed these docs a bit: http://e-docs.bea.com/wls/docs92/webserv/jws.html
excerpt of my class :
@Session(ejbName="myWSBean")
@MethodIsolationLevelPattern(pattern="*", isolationLevel=IsolationLevel.TRANSACTION_READ_COMMITTED)
@JndiName(remote="...")
@RoleMapping(principals="MYUSER", roleName="MYUSER")
@TransactionAttribute(value=TransactionAttributeType.REQUIRED)
@Stateless
@WebService(name="MyServicePort", serviceName="MyService",
targetNamespace="http://.../.../MyInterfaceService")
public class MyWSBean implements SessionBean{
When I try to build the web service with the jws ant task, I get following errors:
[jwsc] [ERROR] - The annotation weblogic.ejbgen.RoleMapping is not allowed on ...MyWSBean because it is a JAX-WS type web service.
[jwsc] [ERROR] - The annotation weblogic.ejbgen.Session is not allowed on ...MyWSBean because it is a JAX-WS type web service.
Seems its not allowed to mix jaxws and ejb3 annotations. What is the way to go to expose my ejb3 bean as a resource?
thx

Thx for your reply.
I did it differently: Creating a EJB3 bean (using the weblogic.ejbgen annotations) and afterwords creating a seperate file for the JAXWS webservice and there injecting the bean via the EJB annotation. Works smoothly.
Although I would rather use 1 file for both sessionbean and web service
Therefore, like I said, in the EJB3 sessionbean I now use following ejbgen annotations:
@Session(ejbName="...",
               runAs="...", runAsIdentityPrincipal="...",
               createAsPrincipalName="...", passivateAsPrincipalName="...",
               transTimeoutSeconds="7200", enableCallByReference=Bool.TRUE,
               useCallerIdentity=Bool.FALSE)
@MethodIsolationLevelPattern(pattern="*", isolationLevel=IsolationLevel.TRANSACTION_READ_COMMITTED)
@RoleMapping(principals="...", roleName="...")
Not sure why this is 'ejbgen' annotations, instead of just ejb or javaee general annotations... Arent there any more standard annotations or so in order to specify these configurations (rolemapping, MethodIsolationLevelPattern, Session, runas, createasprincipalname...) ?
thanks
