To view the discussion, visit: http://community.jboss.org/message/643665#643665 -------------------------------------------------------------- Hello, So I upgraded the JBoss WS to 3.4.1 in my 5.0.1 container and I am running a client which consumes services from another environment. I now get this error when I try to run the application. 21:46:30,678 ERROR [[default]] Servlet.service() for servlet default threw exception java.lang.NoSuchMethodError: org.jboss.logging.Logger.debugf(Ljava/lang/String;[Ljava/lang/Object;)V           at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.configureStub(ServiceDelegateImpl.java:438)           at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.createProxy(ServiceDelegateImpl.java:416)           at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.getPortInternal(ServiceDelegateImpl.java:243)           at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.getPort(ServiceDelegateImpl.java:570)           at javax.xml.ws.Service.getPort(Service.java:99) Anyone seen this before ? I guess jboss logging in the 5.0.1 container is not compatible, but there was nothing in the 3.4.1 install instructions and I am curious how anyone could have made this work. Or am I missing some other dependency ? Thanks, Kevin. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/643665#643665] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
