Hello,

I have here a question regarding the connectivity of a database tool ( DbSchema ) with Firebird.
We want to connect to Firebird using the jdbc driver.
Therefore we load the JDBC driver dinamically using the Java URLClassloader.
We do like this since the driver is loaded dinamically ( the drivers can be loaded during the execution of the application ).
But when connecting we got the exception bellow. Could you help in fixing this issue ?

Thank you,
