Hi all, I am trying to run a pair-wise classification experiment using the DKPro TC framework. The execution fails during the meta-info stage due to a NullPointerException that originates in the CpeBuilder class from UIMAfit v.2.1.0 (hence the post to this list and not the DKpro list). I had a closer look at the code and the NPE is triggered at the following line in the CpeBuilder:
cpeDesc.getCpeCasProcessors().setPoolSize(maxProcessingUnitThreadCount + 2); The underlying root cause is that the casProcessors object returned by the call to cpeDesc is Null, but I don’t understand why. The cpeDesc lists a number of fields as having Null values: org.apache.uima.collection.impl.metadata.cpe.CpeDescriptionImpl: casInitializer = NULL configParameterSettings = NULL configurationParameterSettings = NULL import = NULL sofaNameMappings = NULL configurationParameterSettings = NULL cpeCasProcessors = NULL outputQueue = NULL startAt = NULL startingEntityId = NULL Unfortunately, I am not too familiar with the inner workings of the UIMA(fit) framework so I am not sure how, why and where these fields were set to Null. Could someone perhaps point me in the right direction where I should dig deeper to identify the cause for this problem? Thanks a lot. Cheers, Martin
