WebLogic Server has an interesting "prefer-web-inf-classes" setting that you can define which changes its default class loader behaviour - see 
http://e-docs.bea.com/wls/docs91/programming/classloading.html#1073478

Perhaps that will help.
BTW - you should describe what commons logging problem you actually get to help people here try and help you.

The issue is that since I placed the cxf incubator jar file in the
system classpath, org/apache/cxf/binding/soap/spring/NamespaceHandler
class is loaded by the system classpath. Since this class has a
dependency to spring bean classes, the loading fails. If I placed all
the spring jar files, it does go past the problem I reported earlier but it fails while looking for commons logging. So obviously putting all the classes in the bootloader classpath would work but that is defintely not 
what I am looking for.

Any suggestions on what can be done here?

I definitely have all the classes in the classpath. I can see
all the handler classes in the jar files. It may have
something to do with classloader issue. Due to weblogic
issues, I placed the
"C:\Apps\apache-cxf-2.0.1-incubator\lib\cxf-2.0.1-incubator.ja
r" this path in front of my classpath. Rest all the jars from
CXF library distribution has been copied over to WEB-INF/lib.

I  did follow the tutorial and that's how I have configured
my project.

 From the Java documentation for "NoClassDefFoundException":
"The searched-for class definition existed when the currently
executing class was compiled, but the definition can no longer be
found."

Looks like you're missing a Jar file.  Please make sure you're
including all the Jars referenced here:
http://cwiki.apache.org/CXF20DOC/writing-a-service-with-spring.html

If any one has any suggestion, please advise Thanks

I am just trying to do a very simple web service using

Spring but

have run into an issue. I get the following excpetion

when weblogic

<jaxws:endpoint

</beans>



Any idea what am I doing wrong here. (I did append the

cxf jar in

front of weblogic classpath to get rid of portType not found
error). I'm using weblogic 9.2

Thanks
