ixa-heideltime cannot initialize JCas factory

wmkouw commented 6 years ago

Goal: run ixa-heideltime on a part-of-speech tagged file.

Input: Called compiled jar on alpino-to-treetagger and with default config.props according to instructions

cat in.naf | java -jar target/ixa.pipe.time.jar -m lib/alpino-to-treetagger.csv -c heideltime-standalone-2.2.1/config.props > out.naf

Problem: JCas factory could not be initialized and Cas object could not be generated.

jCas factory in IXAPipeHeidelTime.java is initialized using descriptions, which are taken from config.props:

TypeSystemDescription[] descriptions = new TypeSystemDescription[] {
    UIMAFramework
        .getXMLParser()
            .parseTypeSystemDescription(
                new XMLInputSource(
                    this.getClass()
                        .getClassLoader()
                            .getResource(
                                Config.get(Config.TYPESYSTEMHOME)))),
    UIMAFramework
        .getXMLParser()
            .parseTypeSystemDescription(
                new XMLInputSource(
                    this.getClass()
                        .getClassLoader()
                            .getResource(
                                Config.get(Config.TYPESYSTEMHOME_DKPRO)))) 
};

config.props points TYPESYSTEMHOME_DKPRO to desc/type/DKPro_TypeSystem.xml.

Heideltime does not contain DKPro_TypeSystem.xml.

Commenting out the second description (i.e. UIMAFramework until Config.get(Config.TYPESYSTEMHOME_DKPRO)))) in line 178 to 185 in IXAPipeHeidelTime.java) leads to no initialization errors.

Not closing, because I'm not sure if everything still works.
