Well, any given page creates only one instance of the servlet class, so using
static really would not make any difference here. The string constants are (in
effect) created when the class is first loaded, not on every method call. Also,
most JVMs implement String constants in a manner that they are shared across
classes and instances anyway, although there are no guarantees here.
But people who want to work on improving the quality of the code generated by
Jasper are quite welcome -- in the Tomcat 4.1 time frame, I would like to see a
lot of attention on this particular area.
