Axis vs. JWSDP?

Hello again,

I am a Web services newbie...

Several questions:

1. What is the difference between Axis and JWSDP?

2. Does one require the other?

3. What is the best way to learn web services (good tutorials, URLs, or books)?

Many, many thanks!

Hi

Even I am a newbie. Following is the link I think is best to learn web services.

They are different implementations of the Java Web services technologies.
They both have to deal with XML, SOAP, and WSDL and implement/use the JAXP, JAX-RPC and SAAJ APIs.
The JWSDP (Sun) also deals with UDDI and the JAXR API (jUDDI and UDDI4J are the open source versions.)
JWSDP can support Java Service Endpoints (JSE) and EJB Endpoints, as far as I know Axis (Apache) focuses on JSE.
JWSDP works best with Sun's Java System Application Server Platform Edition 8.1 but can be used with other Application servers; Axis can run with a simple Servlet container like Tomcat or Jetty but will also work with other application servers.
Many people find Axis easier to use than JWSDP.

2. Does one require the other?

No.

3. What is the best way to learn web services (good tutorials, URLs, or books)?

Many people are looking for this and there isn't a good answer. If you going the JWSDP route, use Designing Web Services with the J2EE 1.4 Platform: JAX-RPC, SOAP, and XML Technologies for the high level and do the J2EE tutorials for the low level like:
  • Building Web Services with JAX-RPC
  • A Web Service Example: HelloServiceBean
  • You may also want to download the Adventure Builder reference application and poke around in it.
    If you are going the Axis route follow Ulf Dittmer's recommendations in Starting problem (you may want to read those articles in any case).

    Which one should be used to properly prepare for the Web services exam?

    My choice is the Sun Java System Application Server/JWSDP combo, mainly because of the J2EE tutorials, the Blueprints book and it is a Sun certification after all - but it doesn't hurt to have the Axis/Tomcat combo installed at the same time (just don't run them at the same time).
    You'll will probably also want to review these threads/links:
  • Comparing "JAVA WEB SERVICES ARCHITECTURE" with RMH
  • Any good study guide for SCDJWS?
  • I.M.H.O. preparitions for passing the exam
  • How to read RMH
  • What is the proper web service tool that i can use in the preparation for the exam?
  • Val's SCDJWS Specifications-Objectives Matrix
  • SCDJWS Links

  • (seems www.valoxo.ch isn't responding at the moment.)
