I am using the apache openNLP to find the location in a sentence and i am getting errors when it passes at nameFinder = new NameFinderME(locationModel);
I have tried other examples when it uses NameFinderME, it did not work also. Can somebody figure out the issue.

In case you are using a more recent version of Apache OpenNLP you can directly pass the URL which is returned by getResource to the TokenizerModel constructor.

TokenizerModel tokenModel = 

    new TokenizerModel(apacheOpenNLP.class.getResource("en-token.bin"));  

You should not load the model each time you invoke the tokenizer, the model should be reused for multiple invocations.

Can you try to change the nameFinder to be declared as TokenNameFinder interface type?

Just try to replace

NameFinderME nameFinder = null

with

TokenNameFinder nameFinder = null

Rest all should be same.
