Hi, 

I am trying to integrate Solr - UIMA with openNLP support. 
I had posted this query earlier.I have been working around this to make it work.But no luck. 
PF the thread name: Exception-while-integrating-UIMA-with-Solr
I have created the pear file(packaged and installed)- opennlp.uima.OpenNlpTextAnalyzer_pear.xml 
I am using openNLP -uima annotators for document analysis. 

The pear(xml) file is located at path:D:\temp\opennlp.uima.OpenNlpTextAnalyzer 

folder structure: 
desc,lib,metadata,models and the pear file 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+Integration for integration. 

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

  <str name="analysisEngine">D/:temp/opennlp.uima.OpenNlpTextAnalyzer/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, 
Arun
