Description

Since -nojars does not bundle any application specific dependency (See http://jira.codehaus.org/browse/GRAILS-5174), I created a script based on War.groovy, which creates the WAR file with plugins and any application specific jars but NOT the grails dependencies. This is so that the WAR size is small. The grails dependencies are copied to tomcat6/shared/lib (everything from $GRAILS_HOME/lib and $GRAILS_HOME/dist). However when tomcat is started and the war file (Attached with this issue) is deployed it gives this error and deployment fails:

I am attaching the war file which is from petclinic sample of grails 1.1.1 and the script to create the WAR. To use the script, copy it to $GRAILS_HOME/lib and type grails shared-war inside petclinic sample directory

Attaching the grails generated stactrace.log file. Looks like grails can not instantiate HibernateGrailsPlugin.

It would be nice to support smaller war files that share libs so that multiple Grails war files can be deployed with a small memory footprint.

I get the same error in grails 2.1.1 when generating the war file with:
defaultDependenciesProvided true
in the BuildConfig.groovy file. All I did was copy the additional lib jar files found in a war file made with this set to false (default) into Tomcat /lib/ directory (there is no "shared/lib" in Tomcat 7).

Presumably, this should work; Grails is supposed to keep some jar files in the /lib/ dir of the war file even when defaultDependenciesProvided is true (it indeed has 20 jar files include many hibernate, jersey, and restlet files). This reduces the size of my war file to 8MB down from 30MB.
