Sample Calculator

Hi,

I am trying to execute the calculator sample. The sample is starting and is
reachable via SOAP Messages but there is a problem with the parameters. The
parameters are arriving as null respectively zero if it is a number.

I am running Tuscany in Felix accordingly to the tutorial on the home page.

I simplified the calculator sample:

Calculator.composite

<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903"
targetNamespace="http://sample"           xmlns:sample="http://sample"
name="Calculator">    <component name="CalculatorServiceComponent">
<implementation.java class="calculator.CalculatorServiceImpl"/>
<service name="CalculatorService">            <interface.java
interface="calculator.CalculatorService"/>            <binding.ws
uri="http://localhost:8086/CalculatorService"/>          </service>
</component> </composite>
Interface:

@Remotable public interface CalculatorService {     String add(String n1,
String n2);     double subtract(double n1, double n2);     double
multiply(double n1, double n2);     double divide(double n1, double n2); }

Implementation:

    public String add(String n1, String n2) {        System.out.println(n1 +
" + " + n2 + " = " + (n1 + n2));        return n1 + n2;    }    public
double divide(double n1, double n2) {        System.out.println(n1 + " / " +
n2 + " = " + (n1 / n2));        return n1 / n2;    }    public double
multiply(double n1, double n2) {        System.out.println(n1 + " * " + n2 +
" = " + (n1 * n2));        return n1 * n2;    }    public double
subtract(double n1, double n2) {        System.out.println(n1 + " - " + n2 +
" = " + (n1 - n2));        return n1 - n2;    }

If I trigger the service the SOAP request contains the 2 parameters but on
the console I see that the parameters are null or zero.
There is no error message as far as I can see.

Thx,
Alex


Re: Sample Calculator

Posted by ant elder <an...@gmail.com>.
It looks like the Soap Client is using RPC encoded SOAP messages which
are not supported by Tuscany. Tuscany should really be giving an error
for this, can you raise a JIRA so we can get that fixed. I'm not
familiar with the Soap Client but does it have any config options to
change to not use rpc/encoded, thats a really old style thats not used
much these days.

Re: Sample Calculator

Posted by Alexander Blotny <Al...@fokus.fraunhofer.de>.
Hi,

I found the problem of the null or zero parameters using the Calculator
example. The problem exists using the Soap Client v1.6.3.1 for Mac OS X.
I tried the JAX-WS Client from the website* and the example worked.

* 
http://cwiki.apache.org/confluence/display/TUSCANYxDOCx2x/Running+Tuscany+SC
A+2.x+with+Equinox+and+Felix

If somebody is interested in the problem here are the wireshark traces for
both tests.
In both cases a multiply operation with the parameters 1 and 1 are executed.
The Soap Client returns 0 as result and the JAX WS Client returns the
correct result 1.

Re: Sample Calculator

Posted by Alexander Blotny <Al...@fokus.fraunhofer.de>.
Maybe I should add some information. I am starting the composite in the
BundleActivator with following code:

public class CalculatorActivator implements BundleActivator {    private
Node node;     public void start(BundleContext context) throws Exception {
try {            NodeFactory factory = NodeFactory.newInstance();
String url = ContributionLocationHelper.getContributionLocation(getClass());
Contribution contrib = new Contribution("c1", url);            node =
factory.createNode("Calculator.composite", contrib);
node.start();        } catch (Throwable e) {            e.printStackTrace();
}    }     public void stop(BundleContext context) throws Exception {
if (node != null) {            node.stop();            node = null;        }
}
}

I f I start this bundle everything seems fine and the service is reachable
but there are the problems as mentioned...
