SOAP XML-RPC Confusion

fmisa
Hi OfBiz Developers...

I'm new to OfBiz - evaluating...
Would like to make some calls on Java Service - via a SOAP or XML-RPC client.

The online documentation, tutorials and forum are unclear on how best to invoke a Java method from client (wishing to bypass the OfBiz UI component "screens" hierarchy)

I've been able to externalize by custom service - by adding export to service definition:
engine="java"  export="true"

This auto-generates a WSDL for my service - available from here:
https://localhost:8443/webtools/control/SOAPService?wsdl

However, when I hit my service - using SOAP call - auto-generated from this WSDL definition - I'm getting all sorts of SOAP XML deserialize errors.... right at:

line 424 (Trunk) XmlSerializer >> Node tempNode = mapKeyElement.getFirstChild();

NullPointerException - because mapKeyElement is NULL from previous
line: 422: Element mapKeyElement = UtilXml.firstChildElement(curElement, "map-Key");

The data/elements it's looking for "map-Key" etc. all seem to be there - not sure why I'm getting a NullPointer here - here's a snapshot of the actual XML message being sent:
<?xml version="1.0"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
    <SOAP-ENV:Body>
        <jsx1:testServiceTest xmlns:jsx1="http://ofbiz.apache.org/service/" >
            <map-Map>
                <jsx1:map-Entry>
                    <jsx1:map-Key>
                        <jsx1:std-String>testAttrib1String</jsx1:std-String>
                    </jsx1:map-Key>

                    <jsx1:map-Value>
                        <jsx1:std-String>testKey1</jsx1:std-String>
                    </jsx1:map-Value>
                </jsx1:map-Entry>
                <jsx1:map-Entry>
                    <jsx1:map-Key>
                        <jsx1:std-String>testAttrib2String</jsx1:std-String>
                    </jsx1:map-Key>
                    <jsx1:map-Value>
                        <jsx1:std-String>testValue1</jsx1:std-String>
                    </jsx1:map-Value>
                </jsx1:map-Entry>
            </map-Map>
        </jsx1:testServiceTest>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

So - I backed up - and decided to work with the OfBiz "Ping" service... just to test...
From the OfBiz - ServiceReference List - I can schedule a "Ping" job - and it runs successfully see the attached "workingPing.sqd.jpg" file for sequence...



However, I'm not able to call the "Ping" service via a SOAP call - same error I get with my custom service.
Why is the SOAPHandler failing to process the request message XML ?....
Shouldn't the SOAPHandler delegegate to JavaEventHandler given my service engine type ?

Should I be using XML-RPC instead ?  I cannot find a single example of tutorial that walks you through an XML-RPC example.
See the "failingPing.sqd.jpg" for sequence taken by app - when invoking from my SOAP client...


Why wouldn't the following SOAP call - be processed by the Ping service ?

Request:
<?xml version="1.0"?>

            <map-Map>
                <jsx1:map-Entry>
                    <jsx1:map-Key>
                        <jsx1:std-String value="message" />
                    </jsx1:map-Key>
                    <jsx1:map-Value>
                        <jsx1:null />
                        <jsx1:std-String value="PING_TEST_BOOYAH" />
                    </jsx1:map-Value>
                </jsx1:map-Entry>
            </map-Map>
        </jsx1:ping>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Same error - as my custom service:

Re: SOAP XML-RPC Confusion

Wich Release.revision are you using? (see any bottom of any backend page, after using: ant svninfo)

Please use rather user ML for such questions, see why here :

Thanks
