Integration testing issue: object is not an instance of declaring class

[frederic.conrotte]

Hello,

I'm trying to run a basic integration test with Spring DM 1.1.1. I've red Spring DM docs and watched screencast but i'm still stuck.

In the JUnit test, after injection of the referenced service by Spring DM, when querying the referenced service

m_fooService.echo("Hello World!")

i get the following stacktrace

java.lang.IllegalArgumentException: object is not an instance of declaring class

Here is the JUnit test:

public class FooServiceTest extends AbstractConfigurableBundleCreatorTests
{
	private FooService m_fooService;
	
	public void testFooService() throws Exception {
		assertEquals("Hello World!", m_fooService.echo("Hello World!"));
	}

	protected String[] getConfigLocations() {
		return new String[] {"/org/foo/service/spring/foo-context-test.xml"};
	}
	
    protected String[] getTestBundlesNames() {
    	return new String[] {"org.foo,org.foo.service,1.0.0"};
    }
    
	public void setFooService(FooService aFooService) {
		m_fooService = aFooService;
	}

}

the Spring DM file context

	<bean id="fooService" class="org.foo.service.internal.FooServiceImpl" />
	<service ref="fooService" interface="org.foo.service.FooService" />

the Spring DM Test file context

	<osgi:reference id="fooService" interface="org.foo.service.FooService" />

I have attached the org.foo.service Eclipse project if you need more infos.


I dont get why the "object is not an instance of declaring class", any idea ?


Thanks

Fred
