Souri commented on ANY23-248:
-----------------------------

Hi Lewis, I did not understand your question.
So, I will explain what I did

I have a project A which in I am adding any23 as a dependency. But it was failing on hadoop
due to above mentioned issue(ClassLoader not able to find the Sesame Loader). So, I explicitly
added the rio maven dependencies in my project A - this time the class loader is able to find
Sesame loader and the code started working.

> I am trying to create n-triples from an html string. I am using the following code to
do it:
> StringDocumentSource documentSource = new StringDocumentSource(html, null);
>             ByteArrayOutputStream out = new ByteArrayOutputStream();
>             final NTriplesWriter tripleHandler = new NTriplesWriter(out);
>             Any23 runner = new Any23();
>            
>             runner.extract(documentSource,tripleHandler);
>             tripleHandler.close();
>             String result = out.toString("us-ascii");
>             return result;
> This is giving me the error :
> java.lang.NullPointerException
> 	at org.apache.any23.extractor.SingleDocumentExtraction.filterExtractorsByMIMEType(SingleDocumentExtraction.java:421)
> 	at org.apache.any23.extractor.SingleDocumentExtraction.run(SingleDocumentExtraction.java:223)
> 	at org.apache.any23.Any23.extract(Any23.java:298)
> 	at org.apache.any23.Any23.extract(Any23.java:433)
> I am running this in hadoop. When I run locally with a single file it works, but doesn't
work when run on hadoop.
> Can someone please tell me how to go about this issue?
