Error: Multiple bindings for not supported for service

[mrobin21]

Hello.

I am trying to implement a J2EE Web Service Client in a Session Bean. My JBOSS version is 4.0.1. I get this message when the Bean attempts to make it's first call:

2005-02-24 16:58:19,612 INFO [STDOUT] {http://www.w3.org/2001/XMLSchema}schema already exists

I am using the J2EE 'service-reference' method to look up the required service in JNDI - ejb-jar excerpt follows:

<ejb-name>Gne</ejb-name>

<home>xxx.datastore.session.facade.external.GneHome</home>
<remote>xxx.datastore.session.facade.external.Gne</remote>
<local-home>xxx.datastore.session.facade.external.GneLocalHome</local-home>
<local>xxx.datastore.session.facade.external.GneLocal</local>
<ejb-class>xxx.datastore.session.facade.external.GneSession</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<service-ref>
 <service-ref-name>services/gne</service-ref-name>
 <service-interface>javax.xml.rpc.Service</service-interface>
 <wsdl-file>META-INF/wsdl/gne.wsdl</wsdl-file>
</service-ref>

I have no idea even where to start with this. The WSDL (gne.wsdl) describes a webservice on a .NET server and seems highly complex. There are multiple namespaces.

In the interests of brevity, I have not included all the code, but will if someone asks for it.

Your wsdl service might define multiple ports. In your <service-ref> you should specify which one you want - they will probably have different endpoint addresses as well.

Thanks Thomas.

It seems to define one service with multiple ports, which in turn are associated with port types. See below (I have cut the detail to show the declarations):

<wsdl:portType name="SearchSoap">
 <wsdl:operation name="Authenticate">
 <wsdl:operation name="Search">
 <wsdl:operation name="GetContractGrids">
 <wsdl:operation name="SearchByFareCode">
 <wsdl:operation name="WindowBoardSearch">
 <wsdl:operation name="GNESearch">
</wsdl:portType>
<wsdl:portType name="SearchHttpPost">
 <wsdl:operation name="Authenticate">
 <wsdl:operation name="Search">
</wsdl:portType>
<wsdl:binding name="SearchSoap" type="tns:SearchSoap">
<wsdl:binding name="SearchHttpPost" type="tns:SearchHttpPost">
<wsdl:service name="Search">
 <wsdl:port name="SearchSoap" binding="tns:SearchSoap">
 <wsdl:port name="SearchHttpPost" binding="tns:SearchHttpPost">
</wsdl:service>

I tried putting this into the ejb-jar.xml file:

<service-qname>SearchSoap</service-qname>

Got a new error:

Would really appreciate some more help, thanks Thomas.

You need to use a <port-component-ref> element

j2ee_web_services_client_1_1.xsd

 <xsd:element name="port-component-ref"
 type="j2ee:port-component-refType"
 minOccurs="0" maxOccurs="unbounded">
 <xsd:annotation>
 <xsd:documentation>

 The port-component-ref element declares a client dependency
 on the container for resolving a Service Endpoint Interface
 to a WSDL port. It optionally associates the Service Endpoint
 Interface with a particular port-component. This is only used
 by the container for a Service.getPort(Class) method call.
