Multiple datasets trouble-shooting

[Alex Wolf]

Hi all,

I ran into some trouble today but managed to resolve it, so I figured I'd share my experience in case anyone else has a similar issue.  I'm not a programmer or anything, so there could be some errors below but I think I caused the error(s) and fixed them.

Short version:

1) When making additional datasets, make sure to disconnect Camelot before closing, then reopen to activate new datasets.

2) If Camelot won't launch, look for 'Could not find a camelot jar file' error message.  If that's the issue, try downloading the javascript exe again and using that to repair the jar file.

Long version:

I was trying to set up multiple datasets per the instructions here: https://camelot-project.readthedocs.io/en/latest/datasets.html

I added 3 new datasets, closed Camelot, and then couldn't get Camelot connected again.  Looking in the log, I found ERROR: Could not find a camelot jar file in the installation location.

After searching through this forum, I decide to try reinstalling javascript. Clicking on the newly downloaded file, it gave me the option to repair, so I did that. I was then able to connect to my default dataset. I found I couldn't add a dataset with the same name as what I'd just tried. Sure enough I went looking at  C:\Users\[myusername]\AppData\Local\camelot\Datasets and found empty folders for the datasets I'd tried to make.  I deleted those.  Then I tried again to create a new dataset with one of the old names I'd just deleted.  This time, I made sure to Disconnect first, then close Camelot.  When I opened Camelot again, it seems to be working OK, now with the new dataset as well as my default one.
