Invoking Web Services From a Java Client

Question

I have a simple web app that runs inside Tomcat. I need to call a web service from this web app and I'm not sure how to go about it. It seems there are two methods depending on whether you are using a managed or unmanaged environment:

JNDI service lookup (managed)

and

JAX-RPC ServiceFactory (unmanaged)

...So which technique should I use?

Answer 1

You don't have to necessarily use those techniques. Assuming you're using Axis as the web services engine and ant as the build tool( http://ws.apache.org/axis/java/user-guide.html ), you need to do the following

1) generate the proxy/stub for invoking the web services. This will give you an entry point into calling the webservices
2) provide configuration info for the client -- a .wsdd file
3) know where the WSDL for your webservices is.

如果是网络服务，为什么不使用apache的httpclient呢？
