Hi,
it could work with something like the following code snippet (a unit
test I just committed). There could be a problem with the null value for
the type system location in factory.createTypeSystemDescription() when
you use it with UIMA Ruta 2.3.0 that is not located within a jar (e.g.,
a local project in your workspace).
Let me know if this works for you.
Best,
Peter
String script = "DECLARE MyType;\n W{-> MyType};";
RutaDescriptorFactory factory = new RutaDescriptorFactory();
RutaDescriptorInformation descInfo =
factory.parseDescriptorInformation(script);
RutaBuildOptions options = new RutaBuildOptions();
TypeSystemDescription rutaTSD =
factory.createTypeSystemDescription(null, descInfo, options,
getClass().getClassLoader());
Collection<TypeSystemDescription> tsds = new ArrayList<>();
TypeSystemDescription classpathTSD =
TypeSystemDescriptionFactory.createTypeSystemDescription();
tsds.add(classpathTSD);
tsds.add(rutaTSD);
TypeSystemDescription tsd = CasCreationUtils.mergeTypeSystems(tsds);
TypePriorities tp = TypePrioritiesFactory.createTypePriorities();
FsIndexCollection indexes = FsIndexFactory.createFsIndexCollection();
CAS cas = CasCreationUtils.createCas(tsd, tp, indexes.getFsIndexes());
cas.setDocumentText("This is a test.");
Ruta.apply(cas, script);
Type type = cas.getTypeSystem().getType("Anonymous.MyType");
assertNotNull(type);
AnnotationIndex<AnnotationFS> annotationIndex =
cas.getAnnotationIndex(type);
assertEquals(4, annotationIndex.size());

Hi,
then you have specified the type system lookup in
META-INF/org.apache.uima.fit/types.txt?
You do not want to specify your rules in a separate file? You could then
use the ruta-maven-plugin and include the generated descriptor in your
classpath lookup (I assume). Without files, you need to merge the
typesystem descriptor somehow with the found ones. In both cases,
however, you need to take care of the type priorities. I haven't used
this way yet, so I have to play around a bit in order to learn if
uimaFIT automatically loads the type priotities from the ruta dependency.
I will come up with a working example, but it will take some time (I am
a bit busy this week).
Best,
Peter

Hi Peter,
Thanks very much for your great comment!
The version we are using 2.2.1.
We use JCasFactory.createJCas (uima fit) to create CAS, could you please share
an example
on how to call the method "rutafac.createTypeSystemDescription(ruta,
descriptorInformation, options, classloader)"
By the way, our code is underdevelopment and will be open source for academic
use only.
Thanks.
Min

Peter Klügl commented on UIMA-4480:
-----------------------------------
Much depends on how you use UIMA or to be more precise, on how you create your
CAS. Do you use, for example, a uimaFIT factory method for creating the CAS, or
an analysis engine?
If I know how you create your CAS, then I can provide a simpler code snippet :-)
Is you code open source?

Project: UIMA
Issue Type: Bug
Components: ruta
Affects Versions: 2.2.1ruta
Reporter: Min Jiang
Assignee: Peter Klügl
Fix For: 2.3.1ruta
I used Java code to apply UIMA Ruta rules, but with declare statement, ruta
cannot recognize the new created annotation type.
Here is the code I used:
String rutaStr2 = "DECLARE person; W{REGEXP(\"Patient\") -> MARK(person)};";
Ruta.apply( aJCas.getCas(), rutaStr2 );
The error is like:
