u wanna read page where has jsp format? or are you talking about u wanna write your own jsp page on ur debian box?
if just wanna read jsp page, any web broswer can do so, because jsp uses standard html format...
but if u are talking about writing ur own jsp page and be able to compile with it, you will need a container that recongize jsp code alone with java code.
first u need to have java sdk install, then u wanna install a container, such as tomcat (that will allow to read jsp code)
then just dump ur jsp code in tomcat, and that's it
p.s: using tomcat just an example, there's a lot container out there such as websphere, jrun...etc
