WSDL Exception in webservice

I created my first axis2 webservice and I got following error when I try to invoke the web service through my client which is created using stub.

What could be the root cause for this exception?
Note: I have included wsdl4j and log4j libraries.

Likely a classpath issue? Can't find javax.wsdl.WSDLException. Ensure this is available.

Having issues trying to run a standalone Java 6 program which is packaged in a war file and deployed under tomcat 7

The issue is that when I run it via Eclipse Juno by clicking on it and "Run as Java Application" it works,
but it needs to be to run in a Linux shell script or at least from the Linux shell.
I need it to append all the jar files from $CATALINA_HOME/webapps/myapp/WEB-INF/lib to my classpath.
Here's my code:
package com.myapp.client;
public class ClientApp {
public static void main(String args[]) {
System.out.println("Hi Client");
}
}
When I cd into $CATALINA_HOME/webapps/myapp/WEB-INF/classes/com/myapp/client issue the following command:
java -classpath "/home/devuser/DevTools/apache-tomcat-7.0.32/webapps/myapp/WEB-INF/lib/*:." ClientApp
I receive this exception:

Could not find the main class: ClientApp. Program will exit
When I go to my home dir (/home/devuser) and type this in, it still doesn't work:

Thank you for taking the time to read this... Would appreciate it if someone could assist me.

All of your libraries and classes need to be in your classpath, then the next argument is the path to your class.
java -cp '.:/path/to/libdir/*:/path/to/myapp.war' com.myapp.client.ClientApp

Same as your earlier problem.
For each ClassNotFound exception, search for the jar on the site below which contains this class and put the jar in your classpath
http://www.jarfinder.com/index.php/java/info/org.dom4j.DocumentException shows you need dom4j.jar

Yes, you need the Apache Logging JAR file on your classpath. Download it here: http://commons.apache.org/downloads/download_logging.cgi

Adding the jar files to ant lib will make them available for ant's java process and not your applications java process. Setting your application's classpath correctly must work.
