Executing JNDI based Pentaho reports using the Java API

I am working on the Alfresco Business Reporting project. In there, the tool can execute Pentaho/ Jaspersoft reports (against Alfresco business objects, using the Pentaho/Jasersoft Java API) on a scheduled basis. I ran into the issue of portability of the (Pentaho) reports. The database, url, credentials were not identical on my Development, Test and Production environments… JNDI is the answer.
