Apache CXF—Javascript Client

This page provides an example of generating a Javascript client using the Apache CXFwsdl2js tool. See the list of tools used to generate clients in this document. You can also generate a Java client in Apache CXF.

To generate a Javascript client using the Apache CXFwsdl2js tool: 

wsdl2js -d <output directory> <WSDL URL>

For example: 

wsdl2js -d c:\Temp\MyJSClient
http://zoolander.us.int.genesyslab.com:10080/Genesys/Interaction/WSCP_812_zoo/WebServiceCapturePoint?wsdl

The tool generates a single file that contains a proxy that can send requests to the service and receive replies asynchronously. You must also include the cxf-util.js file, which is part of Apache CXF.

The sample below does not require anything beyond HTML and Javascript (wscp.js is the file generated by wsdl2js): 

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="cxf-utils.js"></script>
<script type="text/javascript" src="wscp.js"></script>

<script language="JavaScript" type="text/javascript">

var gCounter = 0;

function print_list(list, indent)
{
    var r = '';

    for(var i=0; i < list._kvitem.length; ++i)
    {
        r += indent;

	var pair = list._kvitem[i];
	r += pair._key;
	if( pair._value._ValueString )
	{
	    r += " [str] = '";
	    r += pair._value._ValueString;
	    r += "'";
	    r += "<br>";
	}
	else if( pair._value._ValueInt )
	{	
            r += " [int] = ";
	    r += pair._value._ValueInt;
