Definition on class topics

[oaklandar]

I am taking a Java class next week and would like to find out what I will be learning.

Topics include:
Implement JAX-RPC and JAXM APIs

Using Simple Object Access Protocol, enabling objects to exchange messages and call each others methods

Interface new applications with existing Web Services

I need a simple explanation of what I will be learning because I dont know what JAX and SOAP are and would like someone to translate what they are.

JAX-RPC : Java Api for Xml - Remote Procedure Calls.
Back in the day, there was a form of distributed computing called RPC. This is a resurrection of that technology using XML as the data encapsualtion for sending requests to a remote machine to execute a particular function. The JWSDP (java Web Services Developer Pack) uses XML-RPC to build dynamic "web services /SOAP services".

JAXM : Java Api for Xml Messaging
A way of sending XML messages over a network.

SOAP : Simple Object Access Protocol
An XML based protocol for transacting requests/reponses over HTTP (see XML-RPC).

Thanks,

Sounds like I will be learning more XML technology and not Java?
