what causes error? how solve it?

thanks trying out plugin.

you need start h2 database server mode prior running grails app. start 5.9 release, plugin run in-memory h2 database.

please post future question discussion forum of plugin @ http://groups.google.com/group/grails-activiti-plugin faster response.

best regards, chee kin
