proseco's Issues

Search continues after timeout

Hi,

I am trying to get the imageclassification example running. I set the timeout to 20 seconds and the learning type to supervised.

After 20 seconds, I see the message "Time out reached do you want to continue?". When I hit the "Cancel" button, the search continues in the background. The "stop service" button does not seem to have an effect. Even if I stop the spring server, the background processes continue running.

This is the server console output:

Hi,

I have checked out the development branch to try out the imageclassification example. When I am uploading this zip file, I see the following exception in the console:

Move de.upb.crc901.proseco.view.core.Parser to commons

The only reliable way to initialize an interview from an interview.yaml file is via the Parser#initializeInterviewFromConfig method. However, the Parser class is a part of the webserver project and thus not a part of the PROSECO-Api which makes it impossible to create Interview classes / run proseco by just using the API.

Make PROSECO run on Linux

As far as i can see PROSECO uses *.bat files internally. This obviously doesn't work on linux.
It would be great to add the possibility of running PROSECO under linux.
