ah, of course. great catch. thank you. is there an obvious way to trap for this?
i'm working for a large organization that tends to have 1000's of ppl that could be the maker of the XSD. short of me making an FAQ page of best-practices (which no one will read) can i programatically trap for this type of thing, as opposed to having minor issues like this occur, thus causing an OOM error? thanks again On 10/29/06, Michael Glavassevich <[EMAIL PROTECTED]> wrote:
Hi Paul, This happens because you have maxOccurs="50000" on " originDestinationPair". The larger the value of maxOccurs the more memory Xerces requires to build the DFA representation of the content model. If the value is sufficiently large you'll run out of memory. The workaround for this limitation [1] has always been to change large maxOccurs values to unbounded. Thanks.
