Hi,

I try to call a simple UIMA ruta script from uimaFIT in java. It works in
plain UIMA but it didn't work in uimaFIT for me.  Here is the script:

PACKAGE tutorial.entity;
WORDLIST MonthsList = 'month.txt';
DECLARE Month;
DECLARE Year;
DECLARE Date;
Document{-> MARKFAST(Month, MonthsList )};
NUM{REGEXP("19..|20..") -> MARK(Year,1,2)};
Month Year {-> MARK(Date,1,2)};

Here is the java code (based on Ruta doc example):

//System.out.println( "Hello World!" );
        File specFile = new
File("/home/olhome/software/workspace/rutatest1/dateproject/descriptor/tutorial/entity/DateEngine.xml");
            XMLInputSource in = new XMLInputSource(specFile);
            ResourceSpecifier specifier = UIMAFramework.getXMLParser().
                parseResourceSpecifier(in);
            // for import by name... set the datapath in the ResourceManager
            AnalysisEngine ae =
UIMAFramework.produceAnalysisEngine(specifier);
            CAS cas = ae.newCAS();
            cas.setDocumentText("This is my document. March  June
December");
            ae.process(cas);

            JCas jcas = cas.getJCas();
            for (Month month : JCasUtil.select(jcas, Month.class)) {
                   System.out.println(month.getCoveredText());
                }

  This is the pom dependencies:

    <dependency>
       <groupId>org.apache.uima</groupId>
       <artifactId>ruta-core</artifactId>
       <version>2.3.1</version>
    </dependency>

    <dependency>
      <groupId>org.apache.uima</groupId>
      <artifactId>uimafit-core</artifactId>
      <version>2.1.0</version>
    </dependency>


I have the following error:

Exception in thread "main" java.lang.Error: Unresolved compilation
problems:
    Month cannot be resolved to a type
    Bound mismatch: The generic method select(FSArray, Class<T>) of type
JCasUtil is not applicable for the arguments (JCas, Class<Month>). The
inferred type Month is not a valid substitute for the bounded parameter <T
extends TOP>
    Month cannot be resolved to a type
    at tuto.tuto_step0.App.main(App.java:51)


It seems that I am not able to correctly import types like in the maven
example. I am not so familiar with maven. I have put the DateTypeSystem.xml
in a folder called tuto under src folder and add the line
"classpath*:/tuto/DateTypeSystem.xml" in the text file
src/META-INF/org.apache.uima.fit/types.txt.

Any suggestion is welcome. Thank you.

Regards
Olivier
