Re: problems with wsdl understanding

I'm not sure that I understand your error, but I did notice that you haven't defined a type for the "lang", "name", and "path" element definitions.

When using Document style services (which you are), you must reference an element definition in the <part> definition (which you did). When using RPC style services, you must reference a type definition instead.

The ws:filesystem/file element definition looks okay (although I suspect that you really want to use a <choice> group rather than a <sequence> structure -- or perhaps you want to define an enumeration).

Hi, [apologies for the length]

I have read through the docs and spec but I am still unclear on a few things. The samples all work and all is well.

I have created a wsdl file and use the ant task to generate java files, then compile and deploy -- everything works so far. I must be building the wsdl (pasted at the bottom) incorrectly and I don't know enough to see the error (any suggestions on books, websites are greatly appreciated).

In looking at the code I must be doing something wrong with the //message/part element. Am I right to think I can put an element reference there? An example of the request - GetHeadRequest (coming from a .NET client) looks like: <?xml version="1.0" encoding="ISO-8859-1"?> <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/";> <env:Body> <wd:head xmlns:wd="http://xstandard.com/2002/webdir";> <wd:lang>en</wd:lang> </wd:head> </env:Body> </env:Envelope>
and the response - GetHeadResponse looks like:
<?xml version="1.0" encoding="UTF-16"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/";>
  <env:Body>
    <wd:filesystem xmlns:wd="http://xstandard.com/2002/webdir";>
      <wd:parent></wd:parent>
      <wd:name>Library Of Images &amp; Attachments</wd:name>
      <wd:description></wd:description>
    </wd:filesystem>
  </env:Body>
</env:Envelope>
I go the AxisServlet and list available service -- the new service is there. But when I hit the wsdl to see a 'roundtrip' of the schema I get the following error:

AXIS error

Sorry, something seems to have gone wrong... here are the details:

Fault - makeTypeElement() was told to create a type "{http://xstandard.com/2002/webdir}>filesystem>file", with no containing element
