[flexcoders] web service problem

[Cholakyan, Marina]

Hello!

 

I am trying to call web service created in OFBiz framework(it uses axis
java web services).

I am having two problems

 

1)       Here is my flex client code

<mx:WebService  id="ws"
wsdl="http://localhost:8080/webtools/control/SOAPService/getOrderInforma
tion?wsdl" showBusyCursor="true" >     

                  <mx:operation name="getOrderInformation"
result="controller.resultHandlerGetOrderInformation(event)">

                              <mx:request format="xml">  

                                          <getOrderInformation>    

 
<orderId>{myDataGrid.selectedItem}</orderId>


                                          </getOrderInformation>


                              </mx:request>


                  </mx:operation>

      </mx:WebService>

 

And then I do

Application.application.ws.getOrderInformation.send();

      In soap message body my argument orderId equals to null. But if I
pass hard coded string instead of {myDataGrid.selectedItem}. It works
perfectly fine

 

2)       I tried to pass arguments thru Action Script code and I did the
following

      <mx:WebService  id="ws"
wsdl="http://localhost:8080/webtools/control/SOAPService/getOrderInforma
tion?wsdl" showBusyCursor="true" />

 

       And in Action Script

       var selectedOrderId:string =
Application.application.myDataGrid.selectedItem.value;

       Application.application.ws.getOrderInformation(selectedOrderId);

       

      I also tried

<mx:WebService  id="ws"
wsdl="http://localhost:8080/webtools/control/SOAPService/getOrderInforma
tion?wsdl" showBusyCursor="true" >                 <mx:operation
name="getOrderInformation"
result="controller.resultHandlerGetOrderInformation(event)"/>

</mx:WebService>

 

  And in Action Script

        var selectedOrderId:string =
Application.application.myDataGrid.selectedItem.value;

 
Application.application.ws.getOrderInformation.send(selectedOrderId);

     

When I look in the soap message body it doesn't have the wrapper for the
name of the operation, it contains only argument with its value and flex
gives me an error

 

[RPC Fault faultString="Error #1009: Cannot access a property or method
of a null object reference." faultCode="DecodingError"
faultDetail="null"]

tFunction()

      at flash.events::EventDispatcher/dispatchEvent()

      at flash.net::URLLoader/flash.net:URLLoader::onComplete()

 

Please Help!! Can't seem to figure out what is going on. In adobe docs
it says that flex supports both type of mappings RPC and Document. 

Also I can't figure out why variable for the argument is read as null?
If I could resolve the first problem it would resolve my issue.

 

Thanks a lot for your time
