Reading the response of a web service problem.

[LKirby]

In Ebase I've got web service resource that calls an external web service (in this case, its called AuthenticateUser) and gets back the following response document: http://pastebin.com/Y9hv1x3h

I want to be able to get the error, success and ticket attributes (not userid) from the response element but I haven't had much luck so far as I'm fairly new to this stuff. How should I go about doing this?

Thanks,
Luke.

Edit:

Got it working now.

Code: Select all

importPackage(com.ebasetech.xi.api);
importPackage(com.ebasetech.xi.services);


try {
	// call the web service.
	resources.IRWS_AUTHENTICATEUSER.call();
	resources.IRWS_AUTHENTICATEUSER.fetch();
}
catch (e) {
	event.owner.addErrorMessage(e.javaException.message); 
}

//get the response document
var response = resources.IRWS_AUTHENTICATEUSER.getDocument("Response");

var xmlDoc = new XML(response);
// variable xmlResponse get the response element from the response document
var xmlResponse = xmlDoc.child(0).child("response");

// now get the attrubutes error, ticket and success from the response element.
fields.RESPONSE_ERROR.value = xmlResponse.attribute("error").toString();
fields.RESPONSE_TICKET.value = xmlResponse.attribute("ticket").toString();
fields.RESPONSE_SUCCESS.value = xmlResponse.attribute("success").toString(); // this is a boolean field set to checkbox

If you are using an Ebase web service resource which looks like you are from your call:

Code: Select all

resources.IRWS_AUTHENTICATEUSER.call(); 

You can map your document elements directly to your Form fields, including element attributes. So you don't need to do any of the scripting to get response document.

In your web service resource, right click the element/attribute and select attach field. This creates a resource field which you can map to a form field so the value is fetched as soon as you issue the command.

I forgot that i could use XPath to do this easily! So like you said I mapped the response element to a field and changed the XPath to say:

Code: Select all

/tem:AuthenticateUserResponse/tem:AuthenticateUserResult/response/@ticket

. I'll create 2 more fields for the error and success attributes but its a lot easier that the long script I had before.


Thanks
