Java EE (Java Enterprise Edition) General Discussion

I have a simple server program and a simple client program to test axis - soap-rpc style method using Topcat Apache 4.1.

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

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/discovery/tools/DiscoverSingleton
at org.apache.axis.components.logger.LogFactory$1.run(LogFactory.java:45)
at java.security.AccessController.doPrivileged(Native Method)
at org.apache.axis.components.logger.LogFactory.getLogFactory(LogFactory.java:41)
at org.apache.axis.components.logger.LogFactory.<clinit>(LogFactory.java:33)
at org.apache.axis.utils.Options.<clinit>(Options.java:35)
==================================

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-1.0.4.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?
