Default details for a h2Database

Question

similar question to this question but it did not help.

I have h2 deployed on a Jboss 6 server on amazon hosting at the moment. I am using the following details to attempt a connection

            Connection conn = DriverManager.getConnection(
            "jdbc:h2:~/test", "-user",
            "");

I have tried many other combinations including the ones linked above and used the details provided in the tutorials, nothing seems to be working. The following is the stack trace.

Any help on where I am going wrong would be greatly appreciated. Thank you.

Answer 1

I had exactly the same problem once : I could not access to an H2 file-based database. I never specify any user of password for H2 databases. When I had the connection problem "Wrong user name or password", there was already an existing file from a previous run of the application. Removing the existing *.db files solved the problem (I guess it was created with a generated user/password couple, which has changed since).
