NoClassDefFoundError when establishing a connection on DBVisualizer

Question

I've installed my driver on DBVisualizer but when I try to connect to a database using that driver I get the NoClassDefFoundError below.

I suspect it's the Apache Logging classes that it can't find, but I couldn't find how I can edit the classpath in DBVisualizer.

Does anyone know how I can solve this?

My driver is a VJDBC driver, by the way, from the hybris platform.

An error occurred while establishing the connection:

Answer 1

Found it. I have to place the .jar files under DBVISUALIZER_HOME/lib.

The better solution is however, to add the jar files to the Driver Files Path using the Driver Manager, as suggested by Roger, and as stated here in the JDBC drivers that requires several JAR or ZIP files section.
