Matt (and the 10 other people)-
I can see why the problem happens with Tomcat since it calls out.clear()
before it calls pageContext.handlePageException. Since the Tomcat code came
from Sun originally, I'm not entirely surprised that JWS also does it. I
tried your example with JRun (www.allaire.com) and Resin (www.caucho.com)
and I did not get an error. I tried some other funky things to try to get
Tomcat to work, but I just couldn't. I'm still running Tomcat 3.0 here,
though, so I can't tell you if 3.1 fixes it. I imagine that just calling
clearBuffer instead of clear would fix the problem, but the behavior may be
intentional.
One thing about using JRun or Resin for this, you do see the text message
from the included page before you see the exception. I don't think there is
any way that you can include a page then throw an exception and expect the
original output to go away, since including a page requires that the buffer
is flushed.
