Comment - RE: Fun with SOAP

Comment by Axel on 07 Feb 2008 ():

I have done 2 web services projects with domino as a consumer and SAP workflow and Factiva.com services as producers. Ok. Only SAP workflow actually uses SOAP.
I had quite a good experience with going a bit more low level.
XMLSpy has good features to generate sample input/output message files from a WSDL-URL.
This has been a huge time saver, because figuring out the structure of the soap messages from the wsdl is truely complex.
Then I've used my own framework with jakarta-commons HTTP Client and a self written framework based on SAX and some introspection to convert the response from the producer into java beans. Using xpath capabilities of JDom or XOM would have been the better solution than my own framework, but it hasn't been that hard anyway.
This strategy can be used for REST style webservices also. There are lots of webservices out there, which does not use SOAP. Factiva.com for example.

People say that Axis2 and XFire offer HUGE performance gains. Thats certainly an important point.
