Best to convert to JPA, since you cannot currently deploy .har files in JBoss 7.
Thanks Scott, I read in some forums that it is not supported in JBoss 7 but I wasn't able to verify the same on some jboss documentation.
@Scott: could you show me where you the .har is not supported by Jboss 7? I did not see any offical about this.
@yashendra: after converting to JPA, does your app work well?
