I have created a web service using apache axis 2.
I have just created a simple class and then created web service of that class.
The WSDL has been created successfully and i can access the same via URL. Now when i try to invoke the web service method using web service explorer an error is coming.
Can anyone help ?
ERROR

UPDATE -- I just consumed this web service WSDL using soap ui and i am getting perfect response
In the interest of others, i would like to provide you with the reason that caused this issue.
This issue came as there was internal proxy being used wherein the request was going to one server and then was getting redirected to another.
Once i removed the proxy my code started working fine.
Cherio.
