Reg:-Exception while integrating openNLP-UIMA with Solr

[arun abraham <ar...@gmail.com>]

Hi,


I am trying to integrate UIMA with Solr.

I am using openNLP -uima annotators for document analysis.

I have created the pear file(packaged and installed)-
opennlp.uima.OpenNlpTextAnalyzer_pear.xml

The pear(xml) file is located at the system path:D:\temp\opennlp.uima.Open
NlpTextAnalyzer

Above path contains the following folders:

desc,lib,metadata,models and the pear
file(opennlp.uima.OpenNlpTextAnalyzer_pear.xml)
itself.


content of pear file:


<?xml version="1.0" encoding="UTF-8"?>

<pearSpecifier xmlns="http://uima.apache.org/resourceSpecifier">

    <pearPath>D:\temp\opennlp.uima.OpenNlpTextAnalyzer</pearPath>

</pearSpecifier>


I have tested the pear file with CAS visual debugger and could see the
analysis.


I referred the https://cwiki.apache.org/confluence/display/solr/UIMA+In
tegration for integration.


I am providing the location path of the pear file in the AE tag.


  <str name="analysisEngine">D/:temp/opennlp.uima.OpenNlpTextAnalyz
er/opennlp.uima.OpenNlpTextAnalyzer_pear.xml</str>


But when I try to index documents,following exception is thrown:

I could see that its not reading the pear(xml) file, but I am not able to
 find the cause for it.Am I giving the AE incorrectly?Kindly help me on the
same.


Thanks and Regards,

I was able to figure out the issue.I was directly calling the installed pear file in Solr updateRequestHandler.Once I mapped the pear file inside a AE xml file and pointing the AE file in requesthandler solved the issue.
