Answer 5

In case you got stuck with the default non-blank user when running the client, the full set of parameters will get you past that:

java -cp <path_to_h2>\h2.jar org.h2.tools.Shell -url "jdbc:h2:file:<jdbc_url>" -driver "org.h2.Driver" -user "" -password ""

Answer 6

try this:

java -cp h2*.jar org.h2.tools.Script -user "sa" -password "" -url "jdbc:h2:path_to_your_db_file"
