Exception in thread "main" java.lang.NoClassD...

I have a simple server program and a simple client program to test axis - soap-rpc style method.

I am getting errors while running my client program (for both methods - .jws as well as .wsdd)

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/discovery/tools/DiscoverSingleton

==================================

I AM USING FOLLOWING CLASSPATH:

c:\Axis\lib\axis.jar;
c:\Axis\lib\axis-ant.jar;
c:\Axis\lib\commons-discovery-0.2.jar;
c:\Axis\lib\commons-logging.jar;
c:\Axis\lib\jax-1_1-fr-qname-class.jar;
c:\Axis\lib\jaxrpc.jar;
c:\Axis\lib\log4j-1.2.8.jar;
c:\Axis\lib\saaj.jar;
c:\Axis\lib\wsdl4j-1.5.1.jar;
c:\Axis\lib\activation.jar;
C:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar

==================================

Based on the others recommendation I read I have changed some other version of "COMMANS-LOGGING.JAR", but still I am getting same errors.
Can anyone help me what may be wrong?

Instead of .jws method, I have tried .wsdd method also, I am still getting errors.

Help me!

Till now I have no solution...

In my organization, I do not need to write client side program in Java so I have tested client side program using third party vendor software, and now I am getting satisfactory test results.
Server side code is working fine with no change.

I had same problem an hour ago.

I realized I dont have the current directory, represented by '.' (dot) in the classpath.

Try do like this on your classpath:

Old: c:\whatever;c:\more

New: .;c\whatever;c:\more

Notice the extra dot and semicolon at the start of the classpath

That did work fine.

Thanks
