Hi All! I want to call getPoems function from SOAP Call. my web service address is http://seerah.designers99.com/webservice/server.php?wsdl I have used code bellow. 

Titanium.include('funs/suds.js');
 
//=========( SOAP Working )================
Ti.API.info('SOAP Working Start: ');
alert('Start SOAP Call: ');
try{
// var window = Ti.UI.currentWindow;
var window = Ti.UI.currentWindow;
var label = Ti.UI.createLabel({
    top: 10,
    left: 10,
    width: 'auto',
    height: 'auto',
    text: 'Fetching Poem Results from WebService'
});
 
window.add(label);
 
 
var url = "http://seerah.designers99.com/webservice/server.php?wsdl";
var callparams = {
    // FromCurrency: 'EUR',
    // ToCurrency: 'USD'
};
 
var suds = new SudsClient({
    endpoint: url,
    targetNamespace: 'http://seerah.designers99.com/webservice/'
});
Ti.API.info('End SOAP Working: ');
}
catch(e){
 
    Ti.API.info('Error: '+e);
}
 
Ti.API.info('SOAP Call Start: ');
try {
    suds.invoke('getPoems', callparams, function(xmlDoc) {
        var results = xmlDoc.documentElement.getElementsByTagName('getPoemsResult');
        if (results && results.length>0) {
            var result = results.item(0);
            label.text = 'Poem Results are  ' + results.item(0).text + ' <<<<<<<.';
        } else {
            label.text = 'Oops, could not determine result of SOAP call.';
        }
    });
    Ti.API.info('SOAP Call End: ');
} catch(e) {
 
    Ti.API.error('Error: ' + e);
}
alert('End SOAP Call');
 
 
//=========( End SOAP Working )============
Please Help me out to get Poems? I have placed the suds.js in 'funs/' directory I have checked getPoems() function on soapUI-3.0.1 Software which results fine but in titanium it is generating such errors.

  • it's Mitul not Mital ;)

  • all is well. now everything is working fine. Data and SOAP call. I was getting by incorrect tag name 'getPoemsResult'

    xmlDoc.documentElement.getElementsByTagName('getPoemsResult');
    Now I am getting fine with correct Tag Name 'poem'
    xmlDoc.documentElement.getElementsByTagName('poem');
    works fine now :)

var suds;
