Calling OSGi Service with SDO data
----------------------------------
Key: TUSCANY-2307
URL: https://issues.apache.org/jira/browse/TUSCANY-2307
Project: Tuscany
Issue Type: Bug
Components: Java SCA OSGi Integration
Affects Versions: Java-SCA-1.2
Environment: Windows XP, Java Tuscany Sca runtime
Reporter: Roshan Joseph
Fix For: Java-SDO-1.1
Hi,
I am trying to call an OSGi service from my sca java service running in the
Tuscany SCA runtime. I uses the itest\osgi-implementation sample for SDO as my
osgi service and calls the getGreetings method with SDO data as the input
parameter for this call.
I am reusing the HelloWorldService.jar which is in the
itest\osgi-implementation folder for my OSGi service component. The composite
file of my java service is something like as shown below.
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://com.siemens.hintegration";
xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0";
xmlns:dbsdo="http://tuscany.apache.org/xmlns/sca/databinding/sdo/1.0";
xmlns:hw="http://com.siemens.hintegration";
name="motionreactorComposite">
<dbsdo:import.sdo
factory="com.siemens.hintegration.sdo.MotionReactorFactory" />
<component name="MotionReactorServiceComponent">
<implementation.java
class="com.siemens.hintegration.MotionReactorImpl" />
<service name="MotionReactorService">
<interface.java
interface="com.siemens.hintegration.MotionReactorService"/>
<!--JMS Binding-->
<binding.jms
initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
jndiURL="tcp://localhost:61616">
<destination name="activemq/queue/sendQueue"
create="always"/>
</binding.jms>
</service>
<!-- Reference to the OSGi Service -->
<reference name="helloWorldService"
target="OSGiHelloWorldServiceComponent" />
</component>
<component name="OSGiHelloWorldServiceComponent">
<implementation.osgi xmlns="http://tuscany.apache.org/xmlns/sca/1.0";
bundleSymbolicName="ds.helloworld.sdo.HelloWorldService"/>
</component>
</composite>
The actual code in my java component where I make the call to OSGi service is
as follows:
// Call the OSGi service
Name name = HelloworldFactory.INSTANCE.createName();
name.setFirst(firstName);
name.setLast(lastName);
String hello = helloWorldService.getGreetings(name);
getLogger().info("OSGi iTest Sample Call: " + Hello);
getLogger().info("OsgiService called");
In the debug mode when the call reaches the OSgi component, I get a illegal
argument exception. The error log looks like as shown below.
- Exception occured while calling OSGi service
java.lang.IllegalArgumentException: argument type mismatch
