Connection timed out error with JAXWS client

[Rajesh Shet]

We had developed Webservices with JAXRPC api, but now i have modified the client to use JAXWS api instead of JAXRPC, While connecting it creates the soap object, but when i try to call the soap method it gives me the following error
javax.xml.ws.WebServiceException: HTTP transport error: java.net.ConnectException: Connection timed out: connect

Can anyone help me to resolve this issue ???
