WSDL2JS
Most developers who work with web services are familiar with a utility which converts a WSDL into generated code for a given language. Something like wsdl2java will generate java, wsdl2perl will generate perl and so on. What about wsdl2js?
As it turns out, the documentation for ibm_soap mentions that the parser holds JSON markup in a variable - all we have to do is grab the contents of that variable (smdString) and save it off to a file. Below is code that will parse a given WSDL and then copy the resulting JSON into a textbox for easy access.
<html> <head> <title>DsixE WSDL2JS</title> <script type="text/javascript" src="dojo/dojo.js" djConfig="isDebug: false, parseOnLoad: true"></script> <script type="text/javascript" src="ibm_soap/util/WsdlParser.js"></script> <script type="text/javascript"> dojo.require("ibm_soap.widget.SoapService"); dojo.require("dojox.data.dom"); function wsdl2js() { // This is our homebrew wsdl2js. Json code is dumped to a textbox where // we can copy/paste it into a file. var wsdlParser = new ibm_soap.util.WsdlParser(); var wsdl = dojo.byId("wsdl").value; wsdlParser.parse(wsdl); dojo.byId("json").value = "var myService=" + wsdlParser.smdString; } </script> </head> <body> <H3>Generate JSON from WSDL (wsdl2js)</H3> WSDL must not contain externalized schema, all schema must be defined in the WSDL. <br> WSDL URL: <input type="text" id="wsdl" size="80" value="http://"></input> <p> JSON: <br><textarea id="json" rows="20" cols="80">var myService={}</textarea> <p> <input type="button" id="callServiceButton" value="Create JS from WSDL" onclick="wsdl2js()"/> </body> </html>
I wish I could provide a working version on this blog, but I don't have access to a publicly available WAS server. Instead, here's a screenshot of what it looks like:
Now we can include our SOAP service using a script tag instead of parsing a WSDL every time a page loads.
