Re: Problem invoking external web service

[NGUYEN Cong Kinh]

Hi all,

In fact, there are some bizarre errors in BPEL with apache-ode. In my
experience, almost bizarre errors concern variables.

I see there are two bizarre things in your BPEL:

        <bpws:variable messageType="ns0:getSumRequest" name="aIn">
            <bpws:from/>
        </bpws:variable>
        <bpws:variable messageType="ns0:getSumResponse" name="aOut">
            <bpws:from/>

I don't understand why you declare <bpws:from /> in variable declaration
in BPEL.

In addition, to invoke a service, in the deployment file, there are some
differences. For example in two files following:

1) <?xml version="1.0" encoding="UTF-8"?>
<deploy xmlns="http://ode.fivesight.com/schemas/2006/06/27/dd";
    xmlns:pns="http://www.ibm.com/wd2/ode/HelloWorld";
    xmlns:wns="http://www.ibm.com/wd2/ode/HelloWorld";>
  <process name="pns:HelloWorld">
    <active>true</active>
    <provide partnerLink="client">
      <service name="wns:HelloWorldService" port="HelloWorldPort"/>
    </provide>
  </process>
  </deploy>

2)<?xml version="1.0" encoding="UTF-8"?>
<deploy xmlns="http://ode.fivesight.com/schemas/2006/06/27/dd";
    xmlns:pns="http://www.tsi.enst.fr/paam";
    xmlns:wns="http://www.tsi.enst.fr/paam";
    xmlns:vns="http://paam";>
  <process name="pns:WsComposition4Elements">
    <active>true</active>
    <provide partnerLink="client">
      <service name="wns:WsComposition4ElementsService"
port="WsComposition4ElementsPort"/>
    </provide>
      <invoke partnerLink="linkVideo">
                <service name="vns:VideoService" port="Video"/>
      </invoke>
  </process>
  </deploy>


You see in the second file, there is an declaration of invoking a extern
service. If you can't yet solve your BPEL. It must send all of
informations as BPEL, .wsdl, deploy.xml, etc. (to be capable to test).
