Subject Re: MySQL : No suitable driver found for jdbc:mysql
Date Wed, 18 May 2016 16:02:07 GMT
I've digged a bit deeper, and I've got it working by explicitly loading the
MySQL JDBC driver with the following code change in TransactionLegacy.java :

    static {
        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (ClassNotFoundException e) {
            throw new CloudRuntimeException("Failed to load MySQL JDBC
driver", e);
        }

        // Initialize with assumed db.properties file
        initDataSource(DbProperties.getDbProperties());
    }

This is the old way of doing it (< JDBC 4.0)
I know that from that version onwards that these drivers are loaded
automatically, so I thought that our mysql-connector was outdated.
I've replaced it with the latest, but without success. The issue is still
there.

I've got 2 solutions, but either way, it should work with the current
master ACS without changing stuff manually.
* This code change
* Changing the /etc/sysconfig/cloudstack-management file again, so that
CLASSPATH contains the mysql-connector-java.jar again

Any help / suggestions / ideas are much appreciated.

Kind regards,
Nick Livens
