Connecting
to an Existing Web Service
Generating a Web Service requires time, experience, and effort. But
connectiong to a web service is relatively easy.
- There are many Web Services in the public domain that are freely available. www.xmethods.net lists a variety of these services, written in a variety of languages.
- Let's pick a web service and write a simple interface.
- For this example, I chose the Weather - Temperature service.
- The WSDL is available at http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.wsdl
- I created the necessary Java classes from this two ways:
- I ran the wscompile tool from the jwsdp, with the -gen:client flag. It generated about ten classes with relatively long names.
- I also ran it with the wsdl2java tool from GLUE, available at www.themindelectric.com . My full-time employer uses this, and I have found it to be a good comprehensive tool. GLUE generated two source files. I chose to use this method to continue.
