Hi Everyone,
I'm trying to find an example of BPEL process in which we taking the result

documentation page but still not see.

Thanks for any help!

Hi,
The following code snippet invoke a service specified in
InvokeMultiplierService2. And the result is assigned to the input variable
of the next <invoke/> which is InvokeSquareService.

<invoke name="InvokeMultiplierService2" partnerLink="MultiplierPartnerLink"
operation="multiply" portType="ns1:MultiplierServicePortType"
inputVariable="MultiplyInput1" outputVariable="MultiplyOutput1"/>
        <assign name="Assign3">
            <copy>
                <from>
                    <literal xml:space="preserve">
            <tns:square xmlns:tns="http://ws.apache.org/axis2" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance">
                  <tns:param0></tns:param0>
            </tns:square>
            </literal>
                </from>
                <to part="parameters" variable="SquareInput">
                </to>
            </copy>
        <copy>
                <from>$MultiplyOutput1.parameters/ns4:return</from>
                <to>$SquareInput.parameters/ns4:param0</to>
            </copy>
        </assign>
        <invoke name="InvokeSquareService" partnerLink="SquarePartnerLink"
operation="square" xmlns:ns2="http://SquareService.wsdl"
portType="ns2:SquareServicePortType" inputVariable="SquareInput"
outputVariable="SquareOutput"/>

I think this will help you.

Cheers,
Denis Weerasiri.

Hi Sang, 

           I think you want to find a bpel example to join these two
services into a single bpel service. Although this is not the case I am
looking for, I will try to do it for you, I hope I can do it before your
deadline. let's keep in touch..

Cheers,

Chris Ma

Re: Trying to find an example

Posted by phanlesang <ph...@gmail.com>.

Hi Chris,
I'm writing a bpel designer using GWT so that we can design business process
online and using Apache ODE on backend server. My designer is not work well
though. I chose above example to demo for my bpel designer. This is very
simple, for example:

At first, I use Amazon Book Price Finder Service:
http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl
to get price of a book.

Second, I use Currency Converter Service:
http://www.mindswap.org/2004/owl-s/1.0/CurrencyConverter.owl to convert
price (in $USA) to my currency.

I intend to that. Also, I have some days left to accomplish this. Just
wonder if I can :(

Hi Sang, 
I am doing a survey on BPEL, I have written a similar example as you want,
but I think its a toy example, I am looking for a pratical scenario for
using BPEL as your example, may we can do some cooperations to finish our
tasks? you can tell me your case and I will do the BPEL program for you?

Re: Trying to find an example

Posted by Alexis Midon <mi...@intalio.com>.

I can't find an example with 2 invocations, but the following bpel test case
might be a good start for you:
http://github.com/apache/ode/blob/APACHE_ODE_1.X/axis2-war/src/test/resources/TestSoapHeader/HeaderTest.bpel

You could replace the <reply> with a second <invoke> for instance. The idea
is that you can do whatever you want with the outputVariable of your first
<invoke>.
You could for instance use assignments to extract the relevant information
from the outputVariable and prepare the inputVariable of your next
invocation.

I hope it helps.

Alexis
