a servlet link when the deployed webservice uses an ejb link, this are the xml descriptors: configuration.xml: <java-wsdl> <namespaces target-namespace="http://servicios.com/"

</service-endpoint-interface-mapping> </java-wsdl-mapping> The ejb gets correctly deployed as I can see in JBoss console and jmx console. As you can see, the webservices.xml definition file defines an ejb link: <service-impl-bean> <ejb-link>HelloBean</ejb-link> </service-impl-bean> Why does Jboss tries to look for a servlet link with this configuration... I'm using Jboss 4.0.5 GA View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999348#...
