Generating Request/Response XML from a WSDL

By Hường Hana 8:00 AM , , Leave a Comment

Is there a way to generate Request & Response XML formats from just a WSDL file - if the webservice is not live right now.

SoapUI doesn't give me the response unless it contacts the Webservice with a request. Is there any other tool which can do this?

I should assume this information is available - because without it - client stub frameworks like Axis/JAXWS etc won't be able to generate stubs for generating the requesting and then interpreting the response.

Since you are saying the webservice is not live right now, you can do it by creating mockservices which will create the sample response format.

This can be done using soapUI. (I'm using 5.2.1) The title of the question says "Request & Response XML" while the question body says "Request & Response XML formats" which I interpret as the schema of the request and response. At any rate, the following will give you the schema which you can use on XSD2XML to generate sample XML.

  1. Start a "New Soap Project", enter a project name and WSDL location; choose to "Create Requests", unselect the other options and click OK.
  2. Under the "Project" tree on the left side, right-click an interface and choose "Show Interface Viewer".
  3. Select the "WSDL Content" tab.
  4. You should see the WSDL text on the right hand side; look for the block starting with "wsdl:types" below which are the schema for the input and output messages.
  5. Each schema definition starts with something like <s:element name="GetWeather"> and ends with </s:element>.
  6. Copy out the block into a text editor; above this block add: <?xml version="1.0" encoding="UTF-8"?> <s:schema xmlns:s="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  7. Below the block of copied XML, add </s:schema>
  8. Decide if you need "UTF-16" instead of "UTF-8"
  9. The "s:" and the "xmlns:s" should match the block you copied (step 5)
  10. Save this file with ".xsd" extension; if you have "XML Copy Editor" or some such tool (XML Spy, may be) you should check that this is well-formed XML and valid schema.
  11. Repeat for all "element" items in the right hand pane of soapUI until you reach
  12. This way you'll get some type definitions you might not be interested in. If you want to pick and choose, use the following method: Look through the "wsdl:operation" items under "wsdl:portType" in the WSDL text below the type definitions. They will have "wsdl:input" and "wsdl:output". Take the message names from "wsdl:input" and "wsdl:output". Match them against "wsdl:message" names which will likely be above the "wsdl:portType" entries in the WSDL. Get the "wsdl:part" element name from "wsdl:message" item and look for that name as element name under "wsdl:types". Those will be the schema of interest to you.

If you actually have the complete WSDL as a file available to you, you don't even need soapUI.

You can try above procedure out using the WSDL at http://www.webservicex.com/globalweather.asmx?wsdl

Try this online tool: https://www.wsdl-analyzer.com It appears to be free and does a lot more than generate the XML for requests and response. There is also this: https://www.oxygenxml.com/xml_editor/wsdl_soap_analyzer.html, which can be downloaded, but not free.
