Rajini Sivaram commented on TUSCANY-2307:
-----------------------------------------
Roshan,
Is the Java component (which is invoking the OSGi service) inside an OSGi
bundle contribution? If not, will it be possible to make it an OSGi bundle
contribution (jar file with OSGi manifest headers)?

> 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-Next
>
>
> 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";

> <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
