Hello,
well I have the following problem:
I use kornak-api which provides a simple servlet-based recommender application available under the Apache license.
Wenn I want to start the webservice I get the following error:

I think that I get the error because of:
INFO: Marking servlet jsp as unavailable
but I don't know how to fix this. Does anyone know this error and how to fix this? I try it the last 2 days but I can't fix it. :( I tried so much things but without success... :(
I will be happy about every help. :)
Greetings, Clodan
