I want to deploy three Grails web applications in a Tomcat container. I am using Grails 1.3.7 and Tomcat 7.0.23. I want to put all commons jars in a tomcat/shared/lib directory. Why? I want to have smaller war files and reduce the amount of memory required in PermGen.
I configure the next line in conf/catalina.properites
shared.loader=${catalina.base}/shared/lib,${catalina.base}/shared/lib/*.jar
For all three applications, I execute
grails war
I copy all the *.jars under WEB-INF/lib into $CATALINA_HOME/shared/lib
Later I generate the war files without jars for every application
grails war --nojars
I put all three wars in the tomcat/webapps directory. The production dataSource in conf/DataSource.groovy looks as follows for every app.
App A)
production {
dataSource {
dbCreate = "update"
username = "userA"
password="password"
url = "jdbc:mysql://localhost:3306/applicationA"
driverClassName = "org.gjt.mm.mysql.Driver"
}
}
App B)
production {
dataSource {
dbCreate = "update"
username = "userB"
password="password"
url = "jdbc:mysql://localhost:3306/applicationB"
driverClassName = "org.gjt.mm.mysql.Driver"
}
}
App C)
production {
dataSource {
dbCreate = "update"
username = "userC"
password="password"
url = "jdbc:mysql://localhost:3306/applicationC"
driverClassName = "org.gjt.mm.mysql.Driver"
}
}
When I start up Tomcat the logs look like this:

Unfortunately this doesn’t work in Grails, and there are a few more issues than the datasource. We looked at fixing this for 2.0 but there are still issues, so it won’t work until a 2.0.x release.
The problem is static variables in the core Grails jars. Since the classes in those jars are loaded by the shared classloader, the statics are shared throughout Tomcat. As long as the jars are in each war file they’re loaded by the war-specific classloader and there’s no conflict between static variables. So until this is fixed you need to deploy full wars, or at least keep the grails-*.jar files in the wars.
