axis and eclipse, can't deploy web service

Howdy,
I'm new to web services. I set up eclipse with the wtp, set up tomcat and set up axis. They all seem to be working fine.
My problem is that in eclipse after creating a WSDL file I generate all the skeletons and stubs etc using the wizards. This gives me a deploy.wsdd file which I right click on and choose axis > deploy the web service, however this always fails. I have tomcat started when I do this. I'm stumpted, anyone any ideas why it fails.

Thanks
BB

Some things you could check might be:
- In the Axis web app, do you get any errors in the "happyaxis.jsp" page?
- During deployment, are there any error messages, either on the client or on the server?
- Can you deploy successfully outside of Eclipse?

Thanks for the advice, being a newbie I had basically made some errors in the WSDL which was why it wasn't working out, had to sit down and develop a better understanding of WSDL and then fixed it. I thought what I had initially was OK as it was valid, but I guess it can be valid garbage.
