Java Webservice and Flex

Question

Hello All,
I am stuck at getting webservice result from flex. I have
created a webservice which has following method:
@WebMethod
public String Login(@WebParam(name = "userID") String
userID, @WebParam(name = "password") String password) {
// TODO Store privilege and user ID in session
String privilege =
UserManager.getInstance().validateUserLoginInfo(userID,password);
return privilege;
I was getting correct response from this service(as object
format) untill I defined
@WebResult(name="userPrivilege") in the method. after that I
am getting null if I defined Web service defination in flex MXML as
follows:
<mx:WebService id="wsLogin"
service="NMSMainServiceService" port="NMSMainServicePort"
wsdl="
http://localhost:8080/NMS/NMSMainService?wsdl"
>
<mx:operation name="Login"
result="loginResultHandler(event)"
fault="loginFaultHandler(event)">
<mx:request>
<userID>{userID.text}</userID>
<password>{password.text}</password>
</mx:request>
</mx:operation>
</mx:WebService>
I don't know any reason, then if I define resultFormat="xml"
or "e4x" I do get response by event.result however I can not access
a node in the response array or xml.
private function loginResultHandler(event:ResultEvent):void{
//var myXML:Array = event.result as Array;
var can:String = event.result.LoginResponse.userPrivilege;
Alert.show(can);
is giving me error saying : A term is undefined. When I
checked response in log file it is :
<ns2:LoginResponse xmlns:ns2="
http://service.nms.satpath.com/"
xmlns:S="
http://schemas.xmlsoap.org/soap/envelope/">
<userPrivilege>manager</userPrivilege>
</ns2:LoginResponse>
I have created namespace too
private var ns2:Namespace = new Namespace("
http://service.nms.satpath.com/");
private var S:Namespace = new Namespace("
http://schemas.xmlsoap.org/soap/envelope/");
but no luck.
I would really appreciate if somone could help me this,
please do let me know if you need any more information. Please
help, its urgent.
Thanks.

Thanks for your response Sujit, however in this case I can
not store complex results like this:
<S:Envelope xmlns:S="
http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:GetUsersResponse xmlns:ns2="urn:satpath/service">
<users>
<active>No</active>
<address>----</address>
<createdBy>----</createdBy>
<department>----</department>
<email>----</email>
<loginID>admin</loginID>
<phone>----</phone>
<privilege>Manager</privilege>
<superVisor>----</superVisor>
<userName>----</userName>
</users>
<users>
<active>No</active>
<address>----</address>
<createdBy>----</createdBy>
<department>----</department>
<email>----</email>
<loginID>meena</loginID>
<phone>----</phone>
<privilege>Network Operator</privilege>
<superVisor>----</superVisor>
<userName>----</userName>
</users>
</ns2:GetUsersResponse>
</S:Body>
</S:Envelope>
Actually I have a data grid in which I am displaying results
obtained by web service, result is a bean which has all the details
related to a user in the system like userName, loginID, Address,
phone etc. I am getting all the result and displaying them by
<mx:Datagrid dataprovider="myService.myOperation.lastResult"
> and its working fine.
Now I want to display 3 columns (user name, log in id and
user privilege) when I click on one row I want to use states and
transictions so that I can display user deatils (all other
information obtained from the web service) for that I have to store
the result somewhere possibly in a bean so that I can fetch it in
the changed state( which is user detail) based on user has selected
which row.
I don't know how can I store the result in the bean at flex
side, if I declare resultFormat as object I am unable to typecast
it in some collection, if I take xml as result format soap headers
are creating problem. Or should I follow some other approach?
Please help its really urgent.
Thanks for all the help & support.
