in progress exception
i am getting an exception that essentially says:
"cannot set validation to true because i'm busy."
(stack trace below).
i am using the exact same code that i have been using
with the exception of setting validation to true and
specifying a schema to validate against in my test data.
i am in a multi-threaded environment that makes use of
multiple parser instances stored in an object pool. when
the parser is finished (either successfully or when it
throws an exception) it is placed back in the pool for
the next client to use.
is the validation setting a static one? if one parser
is parsing and another is in progress will this exception
be thrown?
am i missing something?
thanks,
rjsjr
stack trace for the exception is:
+ org.xml.sax.SAXNotSupportedException: PAR004 Cannot
setFeature(http://xml.org/sax/features/validation): parse is in progress.

You will get this exception if your program trys to change settings when the
parser instance is still parsing( hasn't return from parse() method).
It is not required to call reset() method before every invocation.

not that either from looking at the code.
i am now thinking i need to call reset() before every
invocation? if this is the case then why would it have
worked before i was using validation but not after?

okay, another question that may be more relevant after i
looked at the setValidation code...
if i throw an exception in my ErrorHandler, does the parser
catch that exception, reset fParseInProgress and then re-
throw that exception or does it just let the exception fly?
