Exposing BPEL process as a webservice inside a webapp
-----------------------------------------------------
Key: TUSCANY-2313
URL: https://issues.apache.org/jira/browse/TUSCANY-2313
Project: Tuscany
Issue Type: Test
Components: Java SCA Samples
Affects Versions: Java-SCA-1.2
Environment: Windows under Tomcat 5.5.25
Reporter: Dalys Sebastian
The goal is to get a bpel process exposed as a webservice and running as part
of a web application. The following method was followed, but an exception was
reported when tested. (The exception is at the end)
The method I followed:
1) I took the sample-helloworld-bpel in your sample and made the following
changes to the maven pom.
a) Added axis-ws binding jar
b) Replaced the host-embedded dependency with host-webapp
c) Created src/main/webapp folder and changed the packaging of pom to
war.
2) The WSDL, the BPEL process and the composite file are exactly same as what's
given by Tuscany sample helloworld-bpel
3) Added webapp/META-INF/sca-contribution.xml file
4) Introduced the "<binding.ws/>" element in the componentType file.
5) After maven packaged it, it was unpacked into Tomcat.
6) I copied the derby database directories (came with ode-1.1) into
WEB-INF/classes.
And when I started up the webapp I get an exception. On removing
the binding.ws element, it starts up correctly.
I am pasting below the contents of sca-contribution file and componentType file
which are
the only new additions I made.
sca-contribution.xml file:
<contribution xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://bpel";
xmlns:bpel="http://bpel";>
<deployable composite="bpel:bpel"/>
</contribution>
componentType file:
<componentType xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:wsdli="http://www.w3.org/2006/01/wsdl-instance";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<service name="HelloService" promote="BPELHelloWorldComponent">
<interface.wsdl
interface="http://tuscany.apache.org/implementation/bpel/example/helloworld.wsdl#wsdl.interface(HelloPortType)"
/>
<binding.ws/>
</service>
</componentType>
