Re: [Springframework-developer] OJB support

[Brian M. <mcc...@fo...>]

I'd be all for it -- though I don't know if the implementation that was 
done is still around, it was a while back =) Explicit permission to 
implement HQL might work. It is one of those "it isn't even worth 
asking the lawyers for the arguments likely to ensue" type questions 
thus far. If you really want it, now that HQL has a real AST generated 
and interpreted an implementation off of the Hibernate one which 
compiles HQL to a QueryByCriteria or ReportQuery in OJB terms would 
probably be fairly straightforward to do. I don't know of any bizarre 
capabilities HQL has which aren't supported in OJB's criteria api. Said 
tool would need to be LGPL so couldn't be checked into OJB, but could 
certainly be made available.

Personally, I have been waiting for the (now released) EJB3 spec to see 
if it supports more HQL'ish queries. Implementing EJBQL(3) should be 
fine.
