Import a Web Service Client from a WSDL in Java

Question

Im trying to use a web service.

My project is Java 6, using Jboss 4.3.2.GA. I've tryied to import the web service using the New-> Web Service Client in Eclipse. Like this tutorial http://www.craigsprogramming.com/2011/03/tutorial-consume-any-web-service-using.html

But when i try to get the Soap Client in this code:

WebServiceEscolaSoapStub service = (WebServiceEscolaSoapStub)new WebServiceEscolaLocator().getWebServiceEscolaSoap();

I get the following error.

org.apache.commons.discovery.DiscoveryException: Class org.apache.commons.logging.impl.SLF4JLogFactory does not implement org.apache.commons.logging.LogFactory

Answer 1

The error is pretty clear.

You are mixing two jars slf4j and commons-logging. Get rid of commons-logging.jar file. On second thought remove all logging for now and just a run webservice client to see if you get an output. Later you can add the logging. This error has nothing to do with webservice error.
