BabelFish Java Soap Example

Download and Install Java SOAP
Will use Apache SOAP as it supports client side usage

Download Apache SOAP at: http://xml.apache.org/dist/soap/

I used version 2.3.1

The directions at: http://ws.apache.org/soap/docs/index.html are useful.

You need to download the following:

mail.jar http://java.sun.com/products/javamail/

activation.jar http://java.sun.com/products/beans/glasgow/jaf.html

Apache Xerces compiler http://xml.apache.org/xerces-j

You need to have the following in your classpath:

soap.jar
mail.jar
activation.jar
xercesImpl.jar

I have yet to determine if one really needs all these jar files
