Interesting – the presenter, Christopher Judd, who is President of Judd Solutions and coordinator of the Central Ohio Java User Group, wrote a childrens book called Bearable Moments about a boy whose mother is in the military and gets deployed.
He’s presenting Consuming and producing web services with WebTools (WST and JST). The overlap between JST and WST is the web services standards: SOAP, WSDL, UDDI. WebTools (WTP) uses Axis, currently 1.2.1.
You can generate web services either top down (WSDL First) or bottom up (Java code first.) There are wizards to help you with either option. There are wizards to create web service clients as well.
You can test your web services via a simple JSP that can be auto-generated. As well, you can publish your web service to a UDDI registry in the creation wizard. There’s also a nice TCP/IP monitor (also known as a sniffer) to help with testing.
