webservice vs. EJB, and wscompile

[chaohua wang]

Hi, Folks, I am new for webservice.

I have couple of questions.
1.)From what I have learned, the web service is like EJB session bean. I know web services communicate by XML message, and not tied to any one operating system and languages. For our pdsstudio application, I wonder what are advantages to use web service comparing with EJB.


2.) I need to use wscompile to generate mapping and wsdl files.
For example, wscompile -cp output/classes -gen:server -f:rpcliteral -mapping jaxrpc-mapping.xml config.xml
But I can�t find wscompile task name in ANT. Is there any another task to replace it?

Thank you very much in advance.

EJBs and web services are not competitive technologies. In fact, they can be complementary. A web service might be used to access an EJB. Grossly over-simplifying, web services are a way of accessing functionality (like a communication channel), while EJBs are used to implement the functionality.

As to wscompile, I have no idea. Is that a proprietary tool?

Sun's samples use asant so it probably has it.
