Re: Stale Object exception
Not 100% on this, but in general when a method returns it can
only return one value, not multiple values. A method can have more
than one route of returning, but only single data items can be returned
with the return statement.
This is valid:
public int addMe() { return sum; } This is not: public int addMe() { return sum, division, subtraction; }
If to Err is human - then programmers are most human of us all.

Re: Stale Object exception
Did you read the API for that exception?
NonUniqueResultException (Java EE 5 SDK)
The query you are using returns more than one result. Change the data to reflect your query (eg make it a single result), or change the query to reflect the data (use a different method to collect more than one result)
