i am new to web services.I may be asking this question wrongly.so forgive me.
In my project i have to consume a webservice using java.Could u plz say me how to Create a client api in axis2 in java to consume the webservice that has been created in vb.net.
thanx in advance.

You can use JAx-WS client side also for consuming web service. Use wsimport utility and point it to the WSDL of hosted webservice. It will generate the client side artifacts which will help in calling the webservice.
