Hi,
I am currently trying to load CAS xmi files and create CAS objects, but I
can't see how to do it.
I have looked at the CASCreationUtils methods, but these all require CAS
objects to be created first, and there is my problem. I am not able to
create an empty CAS object.
I have looked into doing
"CAS cas = (CAS) mUimaContext.getEmptyCas(CAS.class);"
but I am not sure if I am setting up the UIMAContext properly, since I get
null pointer exceptions
I assume the end point would be to use the XMIDeserializer, once I have a
CAS object created. Like..
FileInputStream inputCasStream = new FileInputStream(inputCasFile);
XmiCasDeserializer.deserialize(inputCasStream, cas);
Can you point me in the right direction.....?
Thank you,
Frank,
P.S...
The UIMA annotation viewer ( org.apache.uima.tools.AnnotationViewerMain )
from the uimaj-examples project is able to open these CAS files, along with
the TypeSystem description file, and we are able to view the annotations
there with no problem. So, I assume the cas files are ok.
Here is something else that I tried, that did not work for me....
XMLInputSource xmlInput = new XMLInputSource(inputTypeSystemFile);
//get the type system descriptor from the file
TypeSystemDescription typeSystemDescriptor =
UIMAFramework.getXMLParser()
.parseTypeSystemDescription(xmlInput);
//create a cas manager
CASMgr casMgr = CASFactory.createCAS();
casMgr.initCASIndexes();
//connect the casManager with the type system descriptor file
CasCreationUtils.setupTypeSystem(casMgr, typeSystemDescriptor);
//get the cas from the manager
CAS aCas = casMgr.getCAS();
this also gives me null pointer exceptions....
