[hibernate-dev] OGM (mongodb) on AS 7.1 with Arquillian

Hello, I want to deploy an OGM (mongodb of course) app on AS 7.1 with Arquillian for a demo (at ElsassJUG). I have installed OGM and OGM-monogdb as a module based on the ehcache module (btw, I'll have to create the mongodb part). But when I deploy the app, I have the following error: Caused by: javax.naming.NameNotFoundException: ---PlaceHolderDSForOGM--- -- service jboss.naming.context.java.---PlaceHolderDSForOGM--- Based on the sources, I found this: //we use a placeholder DS to make sure, Hibernate EntityManager (Ejb3Configuration) does not enforce a different connection provider map.put( Environment.DATASOURCE, "---PlaceHolderDSForOGM---" ); The point is I don't know how to avoid this exception. The current version of the project is here: https://github.com/gscheibel/OgmAtElsassJUG The ogm-mongodb module file is here: https://gist.github.com/4588287 The main ogm module file is here: https://gist.github.com/4588301 Any thoughts ? Thanks Guillaume
