> I'm looking at JMSBindingProcessor.read(), and the way the read() method
> relies on itself to advance the cursor past its children's END_ELEMENT seems
> to be a problem.
> The code is:
> while (!endFound) {
> int fg = reader.next();
> switch (fg) {
> case START_ELEMENT:
> String elementName = reader.getName().getLocalPart();
> if ("destination".equals(elementName)) {
> parseDestination(reader, jmsBinding);
> } else if ("connectionFactory".equals(elementName)) {
> parseConnectionFactory(reader, jmsBinding);
> ....
> } else {
> ....
> }
> reader.next(); // PROBLEM!
> break;
> For child element 'SubscriptionHeaders', I could write that as either:
> <SubscriptionHeaders.../>
> OR
> <SubscriptionHeaders...>....</SubscriptionHeaders>
> OR
> <SubscriptionHeaders..... >
> </SubscriptionHeaders>
> The first two shouldn't be a problem, I start with a START_ELEMENT and then
> the next() back in read() advances me over the END_ELEMENT event. However,
> the third is a problem, since there is a CHARACTERS event in the middle, in
> which case the next() back in read() only takes me to the SubscriptionHeaders
> END_ELEMENT, though the code at this point can only deal with 'binding.jms'
> END_ELEMENT, (and since it doesn't get this, we get an error).
> In general, it seems that to deal with this kind of thing, helper methods
> that parse a child element should be responsible for themselves advancing the
> cursor to their own child element's END_ELEMENT.
> For what it's worth, I'm not sure how parseDestination() works either, it
> seems like parseDestinationProperties() is going to advance the cursor too
> far, but maybe I don't fully understand this scenario.
> If I can get my build working, I'll post a recreate test.
