Web services test code generator
Klaus Berg has recently released a test-code generator for JUnit-based Web service clients. If you're developing Web services
using Axis2 and XMLBeans this wizard could turn your JUnit test client coding into a powerful code generation process. It
also has uses for those using GUI-based testing tools like soapUI.

XML documents on the run, Part 1
SAX speeds through XML documents with parse-event streams
One of the oldest approaches to processing XML documents in Java also proves one of the fastest: parse-event streams. That approach became standardized in Java with the SAX (Simple API for XML) interface specification, later revised as SAX2 to include support for XML Namespaces.
