jdbc connection timeout for Weceem plugin

Using the Weceem plugin. After periods of inactivity I get a java.sql.SQLException: Connection is closed error. I normally handle this with DBCP properties in DataSource.groovy thusly:

pooled = true
driverClassName = "com.mysql.jdbc.Driver"
dialect="org.hibernate.dialect.MySQL5InnoDBDialect"
hibernate {
cache.use_second_level_cache =true
cache.use_query_cache = true
cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
naming_strategy = org.hibernate.cfg.DefaultNamingStrategy
dialect="org.hibernate.dialect.MySQL5InnoDBDialect"
}
// DBCP "Keep Alive"
properties {
maxActive = 50
maxIdle = 25
minIdle = 1
initialSize = 1
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
numTestsPerEvictionRun = 3
maxWait = 10000
testOnBorrow = true
testWhileIdle = true
testOnReturn = false
validationQuery = "SELECT 1"
}

I can't figure out why this is not working for the Weceem plugin? Any help is appreciated.

Hi Gary,

It sounds like something is returning a stale connection. Weceem does nothing special here, its all plain Grails GORM.

DBCP pool has known issues however. I suggest you try using the Tomcat-pool (there is a grails plugin for it) that apparently performs and works better.

However you might also want to verify that your production system is running with a good up to date MySQL JDBC driver.

Thanks
Marc
