I'm not sure that the spec says to do this one way or the other, but in the
case of gnujsp, and i believe the .92 reference, a ssi just inline's the
code of your included file. gnu appears to at least do something intelligent
with import directives aggregating them to the top of your code. However, it
wont do anything for multiple bean declarations. for normal java variables
you can get around variable redeclarations by enclosing the include in it's
own scope. But if at the top of all your pages you have a <BEAN name=foo>,
or usebean, gnu puts these all at the beginning of your page and they
conflict. You can get what you want by writing your own function that loads
the servlet you need and calls service on it for you passing in your request
and response. This will in effect compile your subpage seperately run it,
and then continue to run your original page. This has the added benefit of
avoiding any naming conflicts, also you can dynamically generate the name of
the file you are including.
So here's a related question: has anyone gotten BEAN to work with a scope of
request
across included pages? if so what implementation. I noticed in gnujsp that
it checks the request to see if it's stored there, but when it creates the
bean it never sticks it in the request.
