Remote RSS Feeds
My very first JSP application
(perhaps too much for my first app.)
Trying setup and home portal page.
That reads three remote RSS feeds (news, weather, etc...)
It will work for the first few seconds and then stops.
I have to restart the tomcat 6.0.18 server and then it all works again..
(1) Tried using my own DocumentBuilder.parse
Now
(2) Using sun.com rssutils.tld
Both Report FileNotFoundException.
As I say it works, and then stops So it's not a code issue.
It would appear to me, that it remembers the connection and the blocks
that connection after it closes.
I have tried connecting and then waiting and connecting again. Thinking
that the RSS site only allows a one connection within one second.
So it's not that.
It appears more that the connection stays open or is blocked from making
a second connection.
Any help Please!!

Thank You,
But as I said it works, but then quits working.
I have it installed according to the same link, and proof that is works
is I get the page, and I can press refresh a number of times and still
get the feed. BUT if I wait a few seconds (25+) then it quits and comes
back with a 500 Error code which breaks down to a FileNotFoundException
error.
It's the sporadic nature on/off that is puzzling
Thanks All
Barry
