Connect to In-memory grails hsql database using java swing

Grails comes with a Swing Database manager application to connect to your in-memory database.

Start the grails app : grails run-app

Add the hsql db to your classpath. I would just add it your bash_profile/bash_rc file
export CLASSPATH=$CLASSPATH:/usr/local/grails/lib/hsqldb-1.8.0.10.jar

Run the swing app
java org.hsqldb.util.DatabaseManagerSwing

Enter the following settings
Type - HSQL Database Engine In-Memory
Driver - org.hsqldb.jdbcDriver
URL: jdbc:hsqldb:file:/Users/akulkarni/workspace/ares/kwbtMaster/devDB (Point to your local project location)
