Steve Ebersole commented on HHH-7012:
-------------------------------------

Well we only ever need to use the {{Name}} variant when we have to perform binding.  For just doing look ups, the {{String}} variant is fine.  If multiple JNDI implementations have problems with their {{NameParser}} it might be better to switch back to the {{String}} variant for look ups.  I just switched for consistency, but obviously a working solution that accounts for seeming bugs on various platforms trumps consistency :(

If I had to guess, probably the NameParser returned from getNameParser( "" ) for the impls that fall down here are "rooted" at {{java:comp/env}} and does not recognize that as a prefix when passing in the full {{java:comp/env/jdbc/myCompDb}} string.  Kind of retarded NameParser implementation if you ask me, but oh well.  If that is the case, you should be able to name your datasource as {{jdbc/myCompDb}} to Hibernate and this code should then resolve correctly.
