Ok her it is...
public Project loadProject (int projectNumber) throws
PersistenceException{
Project prj;
Database projectData = null;
try{
projectData = projects.getDatabase ();
projectData.begin ();
prj = (Project)projectData.load (Project.class, new Integer
(projectNumber));
projectData.commit ();
}catch(PersistenceException pe){
if(logger.isDebugEnabled()){
logger.debug("There was a problem loading the project.",
pe);
}
throw pe;
}finally{
if(projectData != null){ closeDatabase (projectData); }
}
return prj;
}
Of course there is more to the mapping files....
<class name="com.vort.ads.beans.Project" identity="id">
<map-to table="prjinfo" />
<field name="id" type="integer">
<sql name="id" type="integer" />
</field>
<field name="systems"
type="com.vort.ads.vortechs.beans.VortechsDims" collection="vector">
<sql many-key="projectNumber"/>
</field>
<field name="vortSentrys"
type="com.vort.ads.vortsentry.beans.VortSentryDims" collection="vector">
<sql many-key="prjId"/>
</field>
..
</class>
<class name="com.vort.ads.vortsentry.beans.VortSentryDims" identity="id"
key-generator="IDENTITY">
<map-to table="prjvsdims"/>
<field name="id" type="integer">
<sql name="id" type="integer" />
</field>
<field name="project" type="com.vort.ads.beans.Project">
<sql name="prjId" />
</field>
<field name="manuals"
type="com.vort.ads.vortsentry.beans.VortSentryManuals">
<sql many-key="systemId" />
</field>
<field name="modelDims"
type="com.vort.ads.vortsentry.beans.VortSentryModelDims">
<sql many-key="systemId"/>
</field>
..
</class>
That's it, all there is to it. I'm just trying to load a project, which
in turns load a system, which then loads the model dims.
