Subject RE: (newbie question) missing classs file?
Date Wed, 19 Aug 2009 05:37:30 GMT
Hi Chuck,

Thanks for your note, I think I understand.

I preface the remark below once again, with "being a newbie":

I hadn't gotten around to read everything I should have, but
I was getting confused by the fact that a class file was in
$CATALINA_HOME/webapps/sample/WEB-INF/classes directory and
after my removing it and modifying the source, it didn't
appear in the same directory (nor anywhere under $CATALINA_HOME/webapps)
and yet my modification was reflected in the output page.

What I understood empirically is that there is no need for
a class file in $CATALINA_HOME/webapps/sample/WEB-INF/classes
directory.  If so, why should the distribution come with it?
If it hadn't, it would've been less confusing and I would have
avoided my poor expression "deep secret."

It's not a deep secret.  Look at the JSP doc:

and at conf/web.xml for the JSP servlet parameters.  Note especially the default for the scratchdir

Note that that is mypackage.Hello, not anything associated with a JSP.  Look in the servlet
mappings in webapps/sample/WEB-INF/web.xml to see how to invoke the mypackage.Hello servlet.
