ResourceInitializationException when looking for Type system descriptor in JAR

[Martin Wunderlich]

Hi all, 

I am getting an error during the execution of a BatchTask that I don’t quite understand, see stack trace below. The root cause it that the type system descriptor XML file for the Similarity module is not found in the JAR file. However, when I check the jar with 

jar -tfv /home/w/wunderlichm/.m2/repository/dkpro/similarity/dkpro.similarity.uima.api-asl/2.2.0-SNAPSHOT/dkpro.similarity.uima.api-asl-2.2.0-SNAPSHOT.jar

then I can clearly see that the XML is present: 

   […]

   679 Fri Sep 11 14:17:16 CEST 2015 desc/type/EntailmentClassificationOutcome.xml

  1102 Fri Sep 11 14:17:16 CEST 2015 desc/type/Similarity.xml

   [...]

So, what might be the cause for the file not being found when running the batch task? 

(running DKPro Lab 0.12.0-SNAPSHOT, Similarity-2.2.0-SNAPSHOT, Java 1.8.0_25 on Ubuntu 4.8.2-19)

Thanks a lot. 

Cheers, 

Martin

Hi Martin,

I have never seen this kind of error (Java unable to access a file inside a JAR that clearly appears to be there.

If Java were unable to read the JAR e.g. due to permissions, it would also not know that the descriptors are inside.
So obviously the scanning works but then the extraction does not work.

It also looks like the JAR is ok, otherwise "-t" should fail I guess.

I do not think this is a DKPro/Lab/UIMA etc. problem.

Maybe the file permissions changed *while* your code was running or the file was modified/locked/moved/etc.
after your experiment had started? uimaFIT scans the descriptor locations only once and then keeps them in
a cache assuming that the stuff on the classpath doesn't change at runtime. That might explain why it found
the file but later cannot access it.

Cheers,

Hi Richard,

 

ok, thanks a lot for sharing your thoughts on this. I am currently re-running this experiment to see, if it was only temporary glitch.

 

Cheers,

Martin
