I have a webservice with one method which expects no input parametesrs but returns an array of strings. Was able to consume the webservice using java client but failed to consume it thru coldfusion . The exception messages is SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.
tcpmonitor/ethereal shows the correct soap request/response messages.
There are various array test cases in the testsuite. Please have a look at those.
