Driver class not found: org.firebirdsql.jdbc.FBDriver

Question

I have problem with update from firebird 2.1 to 2.5. If I do it, system respond me this:

Unable to connect to database. Driver class not found: org.firebirdsql.jdbc.FBDriver

Is it problem of PATH ?

update_database:
     [echo] Updating database module: support
[updateDatabase] May 16, 2017 9:14:34 AM org.dbmaintain.datasource.SimpleDataSource createDataSource

Answer 1

This error has nothing to do with Firebird itself, nor the update from Firebird 2.1 to 2.5. This error means that you don't have Jaybird (the Firebird JDBC driver) on the class path of whatever you are executing.

Add Jaybird to the class path and this error should go away.
