Groovy Griffon with Hibernate4 plugin class not found exception

Question

I was looking for a fast and easy way to write a very cross platform desktop application. This leads me to thinking that the JVM is the place to be. Since Groovy (Grails) is used in my workplace I thought I would try Griffon since they claim it is essentially Grails for the desktop.

I wanted a persistence management layer and it doesn't not appear that GORM is showtime ready in this environment so I moved towards hibernate using the Hibernate4 plugin for Griffon.

Not that I've really used Hibernate in general however I believe, based on the guides, that I am doing things correctly. My gatherings indicate that this doesn't support annotations to wire up classes so I am using hbm.xml files.

The provided sample for the plugin isn't complex but I don't understand where I am deviating.

Here is a sample class file as it stands:

package gwash

import groovy.beans.Bindable

class DeliveryMethodModel {
   // @Bindable String propName
}

Here is some of the stack trace:

My xml mapping file:

<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="gwash">
    <class name="DeliveryMethodModel" table="[DELIVERY METHODS]">
        <id name="id" column="[DELIVERY METHOD ID]">
            <generator class="increment"/>
        </id>
        <property name="method" column="[DELIVERY METHOD]"/>
    </class>
</hibernate-mapping>

EDIT: I've removed the brackets and spaces as indicated. Changed the DataSource.groovy to 'create' on the DB side. Still experiencing the same issues. The examples for hibernate integration with griffon/hsqldb/groovy are scant on details. Do I need to create all given properties for the model files for this to parse correctly? I've never used hibernate. Nor groovy. Nor griffon. I would definitely provide feedback for the community if I can get this resolved, if not I'll be rolling me own ORM since this is a rather small project. Rather not roll me own.

Answer 1

do you actually have the strings wrapped with [and ]?

I would suspect that for a class defined as

package gwash
import groovy.beans.Bindable
class DeliveryMethodModel {
    Long id
    @Bindable String method
}

the mapping file would be

<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="gwash">
    <class name="DeliveryMethodModel" table="DELIVERY_METHODS">
        <id name="id" column="DELIVERY_METHOD_ID">
            <generator class="increment"/>
        </id>
        <property name="method" column="DELIVERY_METHOD"/>
    </class>
</hibernate-mapping>
