UIMA XMI File to UIMA CAS

need to convert UIMA XMI File to UIMA CAS. Please point me in 
the right direction.

I am trying to do:

XmiCasDeserializer.deserialize (InputStream, CAS)

The Problem is i can't create an empty CAS that doesn't give me
a NullPointer Exception.

Have you copied the code from the XmiCollectionReader in the examples
project?  What's the stack trace?

Hi there,

This is how I am doing the XMI deserialization:

                 // deserialize the type system
                 final XMLInputSource xmlIn = new XMLInputSource( new 
ByteArrayInputStream( ( byte[] ) someObejct ), null );
                 final TypeSystemDescription tsDesc = 
UIMAFramework.getXMLParser().parseTypeSystemDescription( xmlIn );

                 // deserialize the CAS
                 final CAS cas = CasCreationUtils.createCas( tsDesc, 
null, null );

                 XmiCasDeserializer.deserialize( new 
ByteArrayInputStream( ( byte[] ) someOtherObject ), cas, false );

                 return cas;

It is important to de-serialize the type system as well.

greetings
Diman
