Yes, it is a pain isn't it.
I understand that if the JSP servlet was loaded as a servlet (ie from a
location that the servlet engine performs auto re-loading) rather than via
the class path it would probably work (it does with GNUJsp and JSERV).
However this might be difficult to achieve with JRUN - you'd need to
separate out the required class files for the JSP servlet.
I suppose you could use GNUJsp (with JRUN) - put the classes in with the
rest of your servlet classes.
I don't think many servlet engines will work so that other referenced
classes will re-load if the main servlet/JSP class hasn't changed (too much
of an overhead?).
I used to use a horrible method whereby I made a request to a servlet that
simply called System.exit() - luckily(!) the servlet engine used to get
re-started... :-)
Another nicer method that seemed to work for me was to make a request to a
simple servlet (ie one not referenced via classpath) that you know has been
re-compiled - this should force all classes to be re-loaded (that weren't
loaded via classpath)?
