Subject Re: Set query params without TX?

Is a query a one time use object?  Meaning, I only get to call  
getResultList(), getSingleResult(), or executeUpdate() once and then  
I have to get a new instance.

Also you stated:

When I first wrote the proxy, I tried to implement it using a dymanic  
proxy, but gave up after I discovered the extreme differences in the  
handling of the methods.  Some methods require an active transaction,  
and some are fine without one, but you have to close the em in a  
finally block.  The getQuery methods, need to have the Query object  
proxied, but only if there is no transaction. Some methods like  
joinTransaction(), close(), isOpen(), and getTransaction() just have  
custom rules.

So I could easily create a dynamic proxy, but which strategy would I  
choose for the methods that are "dyanmic" (i.e., the extra methods  
not on the entity manager interface)?
