Answer 1

Please use version: h2-1.4.196 or h2-1.4.194.

Corda as of now uses version ext.h2_version = '1.4.194'. The latest version of the driver is not compatible yet.

Update:

With Corda 4 ext.h2_version = '1.4.197' so use appropriate version of h2 jar if using Corda 4.

Answer 2

Get h2-1.4.194.jar (whichever version Corda is using) from Corda and place it in C:\Program Files (x86)\H2\bin

update h2.bat with h2-1.4.194.jar

it wont show the issue.. it worked for me..

Answer 3

I have been working with H2 all week, this just appeared to me as well. Has to be a bug. The console works as expected though, I was able to edit the database.

Answer 4

java -jar h2-1.4.194.jar should work. Please check version is 1.4.194. Corda official site download (https://docs.corda.net/node-database.html) gives 1.4.197 version of H2 which doesn't work.
