Interesting. I don't get any log output either. This leads to two possibilities: 1) There is no logging code being performed in the classes used by wsconsume 2) One of the classes used by wsconsume is changing the logging settings, thus overriding the log4j.configuration setting. My bet would be with option 1. Back in the book, the tip on page 244 that you referred to specifically calls out issues with logging when running your client app, using wsrunclient.
