Sun webservices tutorial

[Pradeep bhatt]

I have some doubts in the tutorial (JX-RPC)
1. what is the purpose of config-interface.xml and jaxrpc-ri.xml files? I havent understood their differences?
2.The WSDL namespace is urn:Foo.
What does the above mean in config-interface.xml file? Is the namespace defined in WSDl schema?
3. What is service port? Does it refer to the exposed mehod ?

Without knowing in what context "urn:Foo" was used, I would guess that it's a sample namespace for the web service being deployed. In practice, that namespace would be named "urn:com-mycompany-webservices" or "http://mycompany.com/webservices" etc. It could be enlightening to just leave it as it is and see where it ends up in the resulting WSDL document...

 The jaxrpcri.xml file for this example follows:
<?xml version=�1.0� encoding=�UTF-8�?>
<webServices
xmlns=�http://java.sun.com/xml/ns/jax-rpc/ri/dd�
version=�1.0�
targetNamespaceBase=�urn:Foo�
typeNamespaceBase=�urn:Foo�
urlPatternBase=�/ws�>
<endpoint
name=�MyHello�
displayName=�HelloWorld Service�
description=�A simple web service�
interface=�helloservice.HelloIF�
model=�/WEB-INF/model.gz�
implementation=�hello.HelloImpl�/>
<endpointMapping
endpointName=�MyHello�
urlPattern=�/hello�/>
</webServices> 

I did not find the mention of urn:Foo in the generated WSDL file. Am
I missing something ? I am new to Webservices.

I am getting the following error when I build the static client

[echo] Compiling the client source code....

Looks like it is not able to find MyHelloService_Impl class. The class is not generated by the build. Can some one help me?

A portType is like an interface specifying any number of operations (which map to methods in the Java implementation class). Then there's a port which exposes the portType using some particular binding (usually HTTP GET, HTTP POST or SOAP).

What is the difference between service name and service port ? Service name consists of number of servive port, right?

Perhaps you forgot to generate it using wsdl2java?

A service is just a container for the provided interfaces (ports).
In fact, here's an interesting attempt to describe the WSDL element relationships in UML.

Lasse, I am using Sun's tutorial and running the application using JWSDP.
The build script is provided in the tutorial and I havent modified it. I am just following the instructions in the tutorial.
