I have a project to work on weblogic 9.2 web service. when I create a standalone client side. it throw Exception.

java.lang.NoClassDefFoundError: com/bea/xml/XmlException

In the end, I found the solution that is I miss the jar files.
The dependencise List is:
weblogic.jar
webservices.jar
xbean.jar
weblogic-container-binding.jar
ant.jar

Then every thing ok. hahahahaha.......... I am so smart. Yeah...........
