java - Creating a JavaScript SOAP Client -
i'm creating soap client js, first time webservices , must have several mistakes in code.
the poit is, code, cant take acces webservice, don't know how access methods inside. webservice gives me following response:
<h1>version</h1> <p>hi there, axis service!</p> <i>perhaps there form invoking service here...</i> instead of correct xml method i'm calling.
this code of soap client:
<html> <script type="text/javascript"> function run(){ var objxmlhttprequest = new xmlhttprequest(); objxmlhttprequest.open("get", "http://localhost:8080/crunchifyws/services/version?wdsl/", true); objxmlhttprequest.onreadystatechange = function () { //alert(objxmlhttprequest.readystate+" "+ objxmlhttprequest.status); if (objxmlhttprequest.readystate == 4 && objxmlhttprequest.status == 200) { result = objxmlhttprequest.responsexml; alert(objxmlhttprequest.responsetext); alert(objxmlhttprequest.responsexml); } } objxmlhttprequest.setrequestheader("content-type", "text/xml; charset=utf-8"); var packet = '<?xml version="1.0" encoding="utf-8" ?><soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:body><getversion xmlns="http://service.web.com.crunchify/"></getversion></soap:body></soap:envelope>'; objxmlhttprequest.send(packet); // add mentioned below code if application calls webservice synchronously. otherwise use "onreadystatechange" process response. response = objxmlhttprequest.responsexml; alert(objxmlhttprequest.responsetext+ " "+ response); } </script> <head> </head> <body> <button onclick="run()">dale!</button> </body> </html> i think te mistake should in part, but, said, first time , don't know i'm doing.
solved
the first problem on line :
objxmlhttprequest.open("get", "http://localhost:8080/crunchifyws/services/version?wdsl/", true); this url http://localhost:8080/crunchifyws/services/version?wsdl gives list of services can call.
so you'll have :
objxmlhttprequest.open("get", "http://localhost:8080/crunchifyws/services/myservicemethod", true); that's first problem think. in second time, have send parameters not entire soap envelope.
var packet = '<?xml version="1.0" encoding="utf-8" ?><soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:body><getversion xmlns="http://service.web.com.crunchify/"></getversion></soap:body></soap:envelope>'; objxmlhttprequest.send(packet); like :
var parameters = "param1=15¶m2=30" objxmlhttprequest.send(parameters); and method send should out of objxmlhttprequest.onreadystatechange = function (){}
this function callback examine response.
