I am getting the below exception when I try to deploy my web service using the AdminClient utlity. I am using Axis 1.2 Beta . I am able to successfully deploy my service in Axis 1.1. I have also attached the sources of my sample web service along with a README file. Please let me know what is the problem as I need to file a bug report for another issue of mine. I wanted to the test the sample with Axis 1.2 Beta before filing the bug.

}Title: README
Steps to run the MySoapService sample- Compile the sources except MySoapServiceClient.java . Keep the axis jars in the classpath.
- Add the ArrayList serializer files to the web server classpath
- Use the AdminClient utility to deploy the MySoapService
- Generate the client stubs using WSDL2Java utility with MySoapService.wsdl file as input
- Compile the generated stubs and add the classes to the classpath
- Compile MySoapServiceClient.java file
- Run the file to view the output.
