Hello,
using JCas doesn't work here because the UIMA Runtime doesn't import your
JCas class.
To get things working you can do two things:
- Do not use JCas, you can do all operations with the CAS API
- Fix the imports in the UIMA Runtime OSGI Manifest and
only use the modified bundle
HTH,

Hi,
I am trying to extend the Cas editor with my own custom view as in the
documentation in chapter 7.4. But I run into problems when using the JCas.
My code is as follows:
JCas jcas = cas.getJCas();
AnnotationIndex<Annotation> fsIndex =
jcas.getAnnotationIndex(Proposition.type);
FSIterator<Annotation> fsIter = fsIndex.iterator();
while (fsIter.hasNext()) {
Proposition p = (Proposition)fsIter.next();
props.add(p);
}
return props;
The error is:
org.apache.uima.cas.CASRuntimeException: The JCAS cover class
"com.sap.ta.research.argumentation.Proposition_Type" could not be loaded.
