Hi,

I am new to WS. Am preparing for SCDJWS exam. I finished reading Part 1 and II of the RMH book - XML, SOAP, WSDL. I skipped the part III(UDDI) - will do it a little later.

Now I have started Part IV - JAX RPC. Althrough out I am able to understand most of what is described in the book, but am not able to get the bigger picture. Especially because the book is too theoritical. Even while reading JAX RPC, I don't see any complete example which I can deploy and see the result.
I quickly went through the Part VII Deployment. Even this one doesn't give a complete example. I agree it is not tied to a vendor. But it is getting difficult for me to grasp. Do we have a 'Helloworld' webservice example.

Did anyone else face the same problem which I am facing.

Any ideas how to overcome this.

Regards
Vasim

Sounds like you are struggling with two problems, the "bigger picture" (20000 feet perspective) and the "Helloworld" webservice example (sea-level and below).

To address the understanding of the "bigger picture" you may want to divert some of your reading time to Designing Web Services with the J2EE 1.4 Platform: JAX-RPC, SOAP, and XML Technologies.

Now I'm not preparing for the SCDJWS yet - got to get the SCBCD out of the way first - but I've already laid out a strategy to get more acquianted with the "sea-level" concerns. In particular I was going to use the Java Web Services Developer Pack as a starting point (SCDJWS is based on the verion 1.0). This includes the Java Web services tutorial which is an extension of the J2EE 1.4 Tutorial(download. The tutorial comes with a number of examples that can be studied to gain some understanding on how the APIs would be applied.
You may also want to study the Java Adventure Builder Reference application which is now part of the J2EE 1.4 SDK Samples bundle.

Thanks once again Peer. I was able to run my first web service from
