I'm working on a project that is driven by taglibs, basically everything
that needs to be done will be done with taglib (e.g. no java or JSP
actions on the page except the preamble).
Since taglibs always get put into _jspService as new classes, all the
objects are generated on a per-request basis. I'm also using the
servletContext to retain references to objects that need to be kept
across several applications (e.g. database pools, etc). Overall this
works just fine for many things.
Unfortunately I'm getting to a stage where I'd like to optimize the
application by moving the static/semi-static per-request data out into
the persistent space in the servlet. In normal JSP I would do this
using declarations (<%! ... %>), but from a taglib it appears imposible.
I'm not entirely sure that this is the place to make a suggestion for
the next taglib spec release, but it would be useful to provide support
for declarations and/or lifecycle management from within a taglib.
Just a thought.
