GDS Java API - Google Desktop Java API

Hi!

I have seen very few examples of usage of this terrific API.
I have used the JGDQuery but would like to use the benefits of the jgd.comapi but with very little success. I have probably missed something BIG but Please bare with me.
Could somone Please point this n00b into the direction of the "obvoious" solution

The simple code:
// It IS the correct path for the DLL
ComponentRegistrator registrator = new ComponentRegistrator( "./lib/gdapi/x86/");

// I get a warning which I think is normal (I shouldn't be doing this but the first time)
// But I don't know how to detect if the component is registered.
registrator.registerQueryComponent( registrator.getGUID());

// constructs a new query (registration of GDAPI is
// started if it's the first time) (Someone elses comment :-)
QueryCOM query = new QueryCOM( "CBRN");

// This query triggers the error stack, I have tried with 0, 20 but without any
// difference.
QueryResultSet results = query.execute( 1, 20);


Gives the uninformant (for me) message stack:
[INFO] JGDRegister - compReg=jgd.comapi.ComponentRegistrator@18237215{jacobDLLPath=N:\dokument\Martin\Projekt\CBRN\SearchEngine\lib\gdapi\x86\, GUID={488A5393-D843-4f60-A357-68EC5BA63C92}}
