Firebird usage with SchemaSpy – Java based Graphical Database Schema Metadata Browser

On devshed firebird forum someone asked if anyone used SchemaSpy with firebird , and later he got it working , here is the command line option (after installing jaybird.jar)
1) Download the ZIP file for jaybird
2) unzip it
3) Copy the file jaybird-full-2.1.6.jar into a convenient directory
4) specify the full path to the .jar file when starting schema spy

java -jar /home/java/schemaSpy_5.0.0.jar -t firebird -db /var/lib/firebird/2.1/data/employee.fdb -s schema -u SYSDBA -p ******* -o /home/firebird/ -port 3050 -host localhost -dp /home/user/jaybird-full-2.1.6.jar

ps:that is a single line
