[keycloak-user] JAX-WS 2.2 on Keycloak 2.5.1

Hello, There are a number of WCF/SOAP services hosted on separate servers that I need to contact from with within a custom Authenticator in Keycloak 2.5.1. For this task, I have generated SOAP service clients using JAX-WS 2.2 and deployed them with my custom authenticator. Whenever a user hits the authenticator during his login process, though, he gets the following error: org.jboss.resteasy.spi.UnhandledException: java.lang.NoClassDefFoundError: javax/xml/ws/Service The authenticator's module.xml file has the following dependencies listed: <module name="org.keycloak.keycloak-core"/> <module name="org.keycloak.keycloak-model-api"/> <module name="org.keycloak.keycloak-login-api"/> <module name="org.keycloak.keycloak-services"/> <module name="org.jboss.resteasy.resteasy-jaxrs"/> <module name="javax.xml.ws.api"/> <module name="javax.ws.rs.api"/> I would have thought the javax.xml.ws.api dependency would have addressed the issue. Do you know how I can go about loading JAX-WS 2.2 web service clients in Keycloak 2.5.1, or if I should be using a different framework for SOAP calls (I've already tried Axis2, which had its own issues)? Thank you for your help, David Lustig
