UIMA RUTA script with stringfunctions doesnt work when executing from UIMA-Fit

Question

I am trying to execute a simple example Ruta script from a UIMA fit pipeline.

STRING s;
BOOLEAN a;
STRING s2 = "LAuGH";
DECLARE Test;
BLOCK(forEACH) W{}{
    W{->MATCHEDTEXT(s), ASSIGN(a,equals(s,s2))};
    W{->MATCHEDTEXT(s), ASSIGN(a,equalsIgnoreCase(s,s2))};
    W{a ->Test};
}

This script works fine when executing it as a standalone script with a separate RUTA project and the Test annotation is created. However, in a java project with a UIMA fit pipeline, I get the following error:

The script fails to parse, which is strange. I am using the latest version of ruta-core from the maven repo (2.4.0). Has anyone any idea why this is happening? Thanks.

Answer 1

When the analysis engine is created manually with uimaFIT, without using a preconfigured descriptor, but only the implementation RutaEngine.class, you need to configure the parameter additionalExtension yourself. This parameter lists language extension factories.

Changing your java line with

 ... = AnalysisEngineFactory.createEngine(RutaEngine.class);

to

 ... = AnalysisEngineFactory.createEngine(RutaEngine.class, RutaEngine.PARAM_ADDITIONAL_EXTENSIONS, new String[]{BooleanOperationsExtension.class.getName(), StringOperationsExtension.class.getName()});

should do the trick.
