Hum.... your xml file should be referencing other schemas that must be
downloaded in order to validated the contents of the file.
May it be that you cannot reach those?
Anyways, I looked at the code, and that error is thrown when the parser
takes too much time to perform parsing. Here is the code:
public FeatureType getFeatureType() {
if(ft != null)
return ft;
Date d = new Date(Calendar.getInstance().getTimeInMillis() +
timeout);
while ((ft == null) && ((state != FINISH) && (state != STOP))) {
yield(); // let the parser run ... this is being called from
if (d.before(Calendar.getInstance().getTime())) {
exception = new SAXException("Timeout");
state = STOP;
}
}
// the original thread
if ((state == FINISH) || (state == STOP)) {
return ft;
}
return ft;
}
I don't exactly know where, but it seems you can set a maximum parsing
time...
Cheers
Andrea
