Hello
I'm researcher at the chair of Michael Granitzer in Passau. I tried to
setup Apache Stanbol, but still have problems with the configurations.
First of all, i wanted to install Stanbol like described on this site:
http://incubator.apache.org/stanbol/docs/trunk/tutorial.html
But after executing the mvn clean install command i recieve an error
message that some tests are erroneous. In order to finish the
installation i switched the tests off. I don't know why the error
occurs. But thats not the point because Stanbol is working fine. I
aditionally tried to install the eHealth index.
I used the tutorial which can be found here:
https://github.com/apache/stanbol/tree/17db70cb87ae5bbb905c1dbe76fbe4c0ca1dd90d/demos/ehealth
After performing the installation without any problems i get an error
during some tests. I want to submit any sentence and let the Enhancement
Chain ehealth enhance it. Following error message occurs:
Execution of Chain *ehealth* failed in *13ms*.
* 11-58-33.212: *completed* in 1ms : *tika* ( optional , start:
11-58-33.212, completion: 11-58-33.213)
* 11-58-33.214: *completed* in 8ms : *langid* ( required , start:
11-58-33.214, completion: 11-58-33.222)
* 11-58-33.222: *failed* in 3ms : *drugIdExtraction* ( required ,
start: 11-58-33.222, completion: 11-58-33.225)
* 11-58-33.223: *failed* in 4ms : *ehealthExtraction* ( required ,
start: 11-58-33.223, completion: 11-58-33.227)
This is the stack trace of the crash.

I have no idea what could be wrong. You have any suggestions?
Thank you very much.
Yours sincerely, Stefan Zwicklbauer
