Hi,
I am trying to implement oracle vpd in my grails 1.0.5 app and came across this thread. I tried the solution proved by burt but getting an error. I get this error below while starting the app. I am using datasources plugin to access more than one schema. The two classes are exactly same as from the link except they are in different package. I would really appreciate any help.
top of DataSource.groovy:
dataSource {
configClass="com.bwse.vpd.MyHibernateConfiguration"
pooled = true

I googled a bit and found this:
http://javazone.org/howto/hibernate-with-oracle-vpdHe suggests using a hibernate.cfg.xml, but you're just setting a Hibernate property, so you could just put it in hibernate.properties in a regular Hibernate app. In Grails, you should be able to put it in the 'hibernate' block in DataSource.groovy, e.g.
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = true
connection.provider_class='org.javazone.hibernate.MyConnectionProvider'
...
}
I tried this and it didn't work - it sets the property correctly but then ConfigurableLocalSessionFactoryBean overrides the value, setting it to 'org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider'. There might be a simpler fix, but I was able to get it working by subclassing the Grails Configuration class:
package com.foo.bar.MyHibernateConfiguration;
import org.codehaus.groovy.grails.orm.hibernate.cfg.DefaultGrailsDomainConfiguration;
import org.hibernate.cfg.Settings;
public class MyHibernateConfiguration extends DefaultGrailsDomainConfiguration {
@Override
public Settings buildSettings(final Properties props) {
props.setProperty("hibernate.connection.provider_class", "org.javazone.hibernate.MyConnectionProvider");
return super.buildSettings(props);
}
}
Set the 'configClass' property in DataSource.groovy to use the custom subclass:
dataSource {
configClass = com.foo.bar.MyHibernateConfiguration
pooled = true
...
}
Once I did this, I got a ClassNotFoundException as expected since I don't have a org.javazone.hibernate.MyConnectionProvider in my classpath.
Note that Configuration subclasses have to be written in Jave due to Groovy weirdness.
