Try updating the database directly. run sql:
update nuke_services_attributes set PN_VALUE='x' where PN_AID='DefaultTheme
replacing x with the name of your own new theme.
works for me at least.
Use your own DB tool to run the query.
-- another tip:
If you are using hsql, don't bother to download and configure the stuff they tell you at the tutorial... ;-)
Use the hsql (built-in) tool you already have:
1) by executing (under jboss where you have the hsqldb.jar):
java -cp hsqldb.jar org.hsqldb.util.DatabaseManagerSwing
2) connect to the nukes database - I use "HSQL database engine standalone" (make sure jboss is not running):
replace X with a path and the name of the nukes database - under server/default/data/hypersonic usually - see nukesDS
This method can be used to run the setup-scripts, too, if you are building nukes and using hsql (for testing)
Would like to get rid of hsql if only I could make my Firebird work with nukes as I'm using Firebird for all other jboss datasources, too... Darn BLOB's and firebird...
