Can you help for resolve this error,

code :

private static final class PipelineRunner {
private final AnalysisEngine engine;
private final JCasPool jcasPool;

private PipelineRunner(final Pipe pipe) throws ServletException {
try {
engine = createEngine(createEngineDescription(
createEngineDescription(CoreNlpSegmenter.class, CoreNlpSegmenter.PARAM_LANGUAGE,
pipe.getLanguage()),
createEngineDescription(TreeTaggerPosTagger.class, TreeTaggerPosTagger.PARAM_LANGUAGE,
pipe.getLanguage())));
jcasPool = new JCasPool(pipe.getInstanceCount(), engine);
} catch (Exception e) {
log.error("Error loading pipers");
throw new ServletException(e);
}
}

public List<ISentence> process(final String text, final Locale lang) throws ServletException {
JCas jcas = null;
List<ISentence> resultMap = null;
if (text != null) {
try {
jcas = jcasPool.getJCas(0);
jcas.setDocumentText(text);
engine.process(jcas);
resultMap = processText(jcas, lang);
} catch (Exception e) {
log.error("Error processing Analysis engine");
throw new ServletException(e);
} finally {
jcasPool.releaseJCas(jcas);
}
}
return resultMap;
}
}

Your issue seems to be more related to Tree Tagger than to JCasPool.
The latest version of TreeTagger includes several changes, especially in the naming of parameter files. Maybe reverting to 3.0 version could help ?

Best,

This line reads

> boolean isUnicode = "UTF-8".equals(_model.getEncoding().toUpperCase(Locale.US));

... so the problem seems to be that the encoding of the model is unknown. Which model
are you using / which language does `pipe.getLanguage()` return in your case?

Cheers,

Best,
