Getting the specifications is not hard, but using them is a significant
project.
1. Find wsdl4j via web search and use it to analyze the WSDL. It will
also collect the schema types you need for the message elements. (There
is also some wsdl-cracking machinery in axis2 which may be better.)
2. You can use the XML Schema API
http://www.w3.org/Submission/2004/SUBM-xmlschema-api-20040122/xml-schema-api.html#Interface-XSModel
implemented in the Xerces-J package to traverse the XML Schema
components of the types you need for the message. *In principle*, this
is enough to construct a form for input of some type and for displaying
an instance of a type.
3. If you do this yourself, it's a major project. Most likely there is
a way to use XForms.

So, is there any way to easily get both document's specification to
store them and use them for later invocation?.
I've been surfing a lot and found anything. Any reference would be
very helpful, as I'm using this at university's project for a course,
where the time is finite :-P .

<mailto:[EMAIL PROTECTED]>>:
My guess is the problem is in using the WRAPPED_STR style. It's
convenient for getting your input string wrapped up as the desired
soap:body child element, but it causes the response to be unwrapped,
and, as a single object is returned, rather than an array, you're
losing most of the response. If you use a straight document/literal
style/use and do your best to forbid automatic wrapping and
unwrapping,you have to do a little more work on input but you'll have
the full output.
I recall having difficulty at one time getting axis 1.4 to stop trying
to wrap and unwrap.
If you're going to be using DII for arbitrary WSDLs, you probably
would not be able to use wrapping and unwrapping anyway -- not all
doc/lit services can have their responses unwrapped. You should just
work with the full documents required for input and output.
