Embedded Firebird Connection not working

I have been trying to connect to an embedded firebird database. Right now my error is: "Failed to initialize Jaybird native library. This is most likely due to a failure to load the firebird client library." I have used the Driver Manager to set up the driver (Jaybird 2.2.7). I have also copied the driver into the Dbvis jdbc directory and the Driver Manager has found the driver when scans that directory. I have added -Djava.library.path=.... to the dbvis.vmoptions file and pointed to the directory where the jaybird.dll resides. I tried copying the jaybird.dll into other directories where I know dbvis is finding .dll files (like into the java bin). Any additional ideas? thanks Edwin
