HSQLDB connection error

I also miss the app_home and hsqldb folder in de deploy folder

Hi,
Can you please attach here the full IDE log file idea.log?
It can be found from the main menu: Help -> Show log in explorer.

Had the same problem. As it turns out the OutOfMemoryError occured because the port 9001 was already taken (very unhelpful error message). Changing the hsqldb port solved the problem for me.

To change the port go to CUBA -> Main Data Store Settings.. change localhost to e.g. localhost:48152.

FWIW, Port 9001 is used by the Intel(R) Graphics Command Center Service on Windows.

For future reference, the exact exception message (idea.log) is as follows:
