Subject Re: EJB Relationship Mapping Names
Date Thu, 28 Jul 2005 03:07:45 GMT
	I don't like including fields for documentation purposes that have 
a name that doesn't make it clear that they're only for documentation.  
As Jeremy just demonstrated, it's easy to convince yourself that those 
fields should be used in some cases (and I was moderately convinced of 
that myself earlier this evening).  But in fact, they're totally 
unnecessary, and if you set them to contradict the same fields in 
ejb-jar.xml for the same relation (or relationship role) then there's no 
ill effect whatsoever.

	If we were going to try to match the ejb-jar.xml schema, then we
should validate that values are the same across the ejb-jar block and
openejb-jar block (assuming they're both present).  But really, what's the
benefit of not just including a "description" element instead?  That way 
someone can put in "matches relation 'foo' in ejb-jar.xml" or they can put 
some other meaningful description or leave it out entirely, and it's 
obvious that it's not an important field as far as the server is
