Hi,
I have a portlet working which does an address book lookup. At least,
it works some of the time! Others, it just posts a blank page and the
log shows the exceptions listed below.
The WEB-INF/xsl/ParseHTML.xsl file is where it should be - and I know
it's being found some of the time at least! I also pared the stylesheet
right down to a single line of "Hello World" in case there were parsing
errors in it - same behaviour: it is displayed when the byxml URL
returns short results, and not with long ones.
I'm pretty sure the problem is something to do with the size of the
reply. If there are 6 or less results, then it works fine, if 11 or
more, then it fails. (I couldn't find an example in between, but it
seems fairly consistent). Each result is fairly big, so I can imagine
that this data might cause problems. I've also tried storing the XML
data returned as a static file, and that works fine with my portlet,
even with a lot of data in it. The problem seems to be catching it
dynamically.
I suspect the "Resetting to invalid mark" error is related to the
size of the XML data. Has anyone seen this before? Is it a known
limitation or have I misconfigured Jetspeed? Could it be a Tomcat
problem? Or even Java?
Any ideas appreciated! I'm running Jetspeed 1.3a on Tomcat 3.2.1.

In case it helps, the Exception is being trapped in this line of Java:
try

return new ClearElement( SimpleTransform.transform( UrlName, StylesheetName ) );
}
catch (SAXException e)
{
Log.note("Found a %^&*$@# SAXException");
Log.error(e);
