I tried the CloudKVS-example Erel made, installed only the B4J-client.
It does not work for me. For making another program work I run my B4J with Java19, maybe this is the reason for this error (but I am not able to step back, this would create problems in the other projects).
As I understand, the example code should write into the SQL-database DB.DB (independing of a server connection available). The database will be created but remains empty and the log shows, that database is not reachable with the loopback-IP just after starting the little program. This is what I get just after starting the program:
A click on the colour button or choosing a number will not change the database. The error happens again, program is not crashing.
The following picture shows the database db.db. Created, but untouched...
Any ideas?
