Subject RE: Can't find lookup dictionary from pear
Date Fri, 02 Nov 2012 18:42:02 GMT
Hi Kline,
I presume this is cTAKES version 2.5?
Is the parent folder of "drugnerrrsources/lookup/g2_index" in the classpath of your container
(jboss?) ?
My guess is that:
1) The resource is not in the classpath
2) The g2_index was lost during the creation of the pear and eventually into the war? i.e.
does the new g2_index folder really exist in the target folder where the old classpath used
to point?

Note: You can also try an file absolute path to verify that indeed that is a classpath issue.

Hope that helps.

Subject: Can't find lookup dictionary from pear

I am using the cTAKES DictionaryLookup pipeline to find drug mentions in documents.  When
I run this from eclipse it works perfectly.  But when I run from a pear file that I generated
it fails.  It appears that it cannot find the Lucene lookup dictionary folder that I created. 
This is the exception:

       ... 16 more
Caused by: drugnerresources/lookup/g2_index
       at edu.mayo.bmi.uima.core.resource.FileLocator.locateExplicitly(
       at edu.mayo.bmi.uima.core.resource.FileLocator.locateFile(
       at edu.mayo.bmi.uima.core.resource.LuceneIndexReaderResourceImpl.load(
       ... 52 more

There's a large stack trace before this but this is the relevant part.  It gets to this code
(locateExplicitly()) only if a class loader get resource call fails.  That should probably
have worked.

In my DictionaryLookupAnnotator I have this:


You can see the definition of IndexDirectory is what it cannot find.  The location does exist
at <project_root>/resources/drugnerresources/lookup/g2_index.  I replaced g2_index
with rxnorm_index, which is something that came with the cTAKES distribution and that does
not work either.

When I build my pear file I include only the desc, resources, and metadata folders from my
project.  The pear goes into the war directory and the war is deployed to a jboss 7.1 server. 
I can see the pear being unpacked when the war is deployed.  Without the drug lookup all
of this has worked perfectly for months.  But this is the first time I am trying to use the
cTAKES drug lookup.
