Grails and SQLite - sqlite

Question

Trying to get SQLite working with grails...stuff I've found on the web seems a little dated - references to ivy and plugins and such, but based on these:
http://stackoverflow.com/questions/1199512/grails-sqlite
http://bigohno.blogspot.com/2010/01/groovy-on-grails-sqlite.html
http://maven-repository.com/artifact/org.xerial/sqlite-jdbc/3.6.17
I've been able to get it working in a test environment...oddly, when I "prod war" my grails app and deploy to tomcat it fails with:
Dialect class not found: hibernate.SQLiteDialect
Here's my setup:
in conf/hibernate added a class for the SQLiteDialect. This .java was taken from here http://code.google.com/p/hibernate-sqlite/
Then in my DataSource.groovy I have:
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
development {
dataSource {
// SQLite
// !!!see also BuildConfig for Dependancies!!!
dbCreate="update"
url='jdbc:sqlite:C:\\sqlite-shell-win32-x86-3080100\\rss_1.db'
logSql="true"
dialect="hibernate.SQLiteDialect"
driverClassName="org.sqlite.JDBC"
readOnly="true"
}
}
production {
dataSource {
// SQLite
dbCreate="update"
url="jdbc:sqlite:/opt/sqlite/dbs/rss/1/rss_1.db"
logSql="true"
dialect="hibernate.SQLiteDialect"
driverClassName="org.sqlite.JDBC"
readOnly="true"
showsql="false"
}
}
}
and in BuildConfig.groovy I have:
dependencies {
runtime 'org.xerial:sqlite-jdbc:3.6.17'
}
I also jar'd up the .java dialect class and put in in lib - some posts said this helped. I also put sqlite-jdbc-3.7.15-M1.jar in lib.
Now when I run-app in my dev environment it runs fine...but when I deploy to tomcat I get the dialect error.
Is there something special I need to do to the prod environment for the dialect?

Here's how to setup SQLite with Grails:
Download SQLite from http://www.sqlite.org/download.html , extract and save to a directory. You may also want to create directories for your databases.
Download SQLite JDBC jar from https://bitbucket.org/xerial/sqlite-jdbc and put the jar in your grails lib directory.
Download a SQLIte dialect...google search as there are many, but you may reference https://github.com/gwenn/sqlite-dialect or https://gist.github.com/virasak/54436
In grails, create a class in src/java and put your dialect code in.
I also jar'd this class up and put the jar in lib.
Setup your grails datasource, e.g.,:
dataSource {
// SQLite
dbCreate="update"
url="jdbc:sqlite:/opt/sqlite/dbs/rss/1/rss_1.db"
logSql="true"
dialect="SQLiteDialect"
driverClassName="org.sqlite.JDBC"
}
NOTE: Depending on whether your sqlite dialect class is in a package, you may need to prefix the package name to the dialect above (mine was not).
In BuildConfig.groovy, add a dependency to sqlite jdbc, like so:
dependencies {
runtime 'org.xerial:sqlite-jdbc:3.6.17'
}
That's what worked for me!
