Issue importing CSV file #89

Closed aweaver1fandm closed 3 years ago

aweaver1fandm commented 3 years ago

unitime.txt I have a user trying to import some data as a CSV file (I renamed the file here to be able to upload, original file name was: Unitime Class File- test.csv

When they do that they get a null pointer exception (See image that hopefully uploaded) image The unitime logfile on the server has almost no other information that is different from what is on the screen...

Any ideas what may be causing this issue?

It looks to me like jython library may be missing from the tomcat lib directory. Can you check to see if the file "jython-standalone-2.5.3.jar” exists in the lib folder for the tomcat you are using? Let me know if it is missing and I can help you obtain a copy.

Thanks, Stephanie

I copied the jar file into /var/lib/tomcat9/lib, chowned it appropriately and that seems to have corrected that issue but then the script processing dies with the following. If I had to guess it looks like it may be a data issue where the code expects a number but isn't getting one so I'm looking more into it image

Based on the error, the problem is likely a badly formatted start time string for a section.

Closing the original issue as resolved by having the jython file. I will say that the few places I saw build/install instructions, none of them mentioned the need for the Jython file. The latest error I am working through and may have resolved. One of the classes had start time set to 0 and end time set to 1. If fixing those does not resolve the issue I will keep looking at the data. Thank you for the help

UniTime does not support running Python scripts out of the box (mostly because the jython library is very large and it is not needed by most users -- e.g., most of the Documentation/Scripts run using the Java's default JavaScript engine). The ability how to enable Python on the Scripts page is described in the help page for the Scripts page, see http://help.unitime.org/Scripts, which is also available when you click on the question mark next to the page name.
