Deploying code to production can be filled with uncertainty. Reduce the risks, and deploy earlier and more often. Download this free guide to learn more. Brought to you in partnership with Rollbar.

Here's a snippet for invoking Jaggery, a framework to write webapps and HTTP-focused web services for all aspects of the application: front-end, communication, Server-side logic and persistence in pure Javascript.

var invokeRetrieveArtifactId =  function (applicationKey,version,revision){
    var ws = require('ws');
var retrieveArtifactIdProcess = new ws.WSRequest();
var options = new Array();
options.useSOAP = 1.1;
options.action = "urn:retrieveArtifactId";
options["HTTPHeaders"] = [ { name : "Cookie", value :modManager.getAdminCookie() }];
var payload = '<p:RetrieveArtifactIdRequest xmlns:p="http://retrieve.core.appfactory.carbon.wso2.org"><p:applicationId>'+applicationKey+'</p:applicationId><p:version>'+version+'</p:version><p:revision>'+revision+'</p:revision></p:RetrieveArtifactIdRequest>';
var result;

try {
   var endPoint =getProperty('ServerUrls.AppFactory')+'RetrieveArtifactService'; // provide the endpoint
   retrieveArtifactIdProcess.open(options,endPoint, false);
   retrieveArtifactIdProcess.send(payload);
   result = retrieveArtifactIdProcess.responseE4X;
   var resultNS = new Namespace("http://retrieve.core.appfactory.carbon.wso2.org");
   var artifactDetails = result.resultNS::["return"].text()

   if(log.isDebugEnabled()){
       log.debug("Invoking service endpoint:"+endPoint+" returned result:"+result);
   }
    return artifactDetails;
} catch (e) {
   log.error("Error while retrieving the artifact id"+applicationKey + "\n"+e.message);
   throw "Error while retrieving the artifact id"+applicationKey;
   }
}
