calling Java function in Matlab and getting wrong return type

Hello

I am trying to implement a Java Api (MetaMap) in Matlab on MAC OSX. It works in Eclipse with my .jar files and packages. I have added the .jar files to the class path and imported the package in Matlab

The Java Code looks like this:

MetaMapApi api = new MetaMapApiImpl(); List<Result> resultList = api.processCitationsFromString(heart); Result result =resultList.get(0); Utterance utterance = (Utterance) result.getUtteranceList();

In Matlab I coded the following:

api = MetaMapApiImpl; resultList = api.processCitationFromString('heart'); result = resultList.get(0); utterance = result.getUtteranceList;

The problem is I get the correct return type for the first 3 lines but when I call the getUtteranceList method I get a java.util.List return type and not the java.util.List<Utterance> type as expected.

In addition when i try to access methods in some classes like methodsview(PCM) I get the following error:

No constructor 'gov.nih.nlm.nls.metamap.PCM' with matching signature found.

Any idea why I am getting the wrong return type. My code works in Eclipse with the same .jar files and packages. Is there a way to see the classes and class hierarchy in Matlab. Has anyone implemented the MetaMap Api in MatLab?

Thanks very much Sanjeev
