For starters, no JSP should make any kind of I/O call, including WS calls - move that code into a backing bean.

Axis (like most SOAP toolkits) includes a tool for creating client code for accessing a given WSDL. Check its documentation for "wsdl2java".

Hi,

I have created the client using myeclipse.
And now its running well.

But how can i call this using jsp page.

Thanks

Some source files should have been created. Consult the documentation of whichever WS plugin you're using for creating the client; it should tell you where to find them.
