Is the class 'org.apache.commons.logging.LogFactory' on the classpath of the client?
Quote from the Axis documentation:
To redistribute an application running Axis, you need to redistribute
A logging implementation compatible with commons-logging. As Java1.4's intrinsic logging facility is compatible, you do not need to include a logging JAR for Java1.4. Otherwise the log4j.jar is a good one to use
A logging configuration file for your chosen logger.
An XML Parser. Java1.4 ships with crimson, although the axis team strongly recommend xerces over crimson.
So you need to make sure all mentioned jars are on the classpath
You should be able to find them in the JBoss distribution
