Jasper is pretty easy to embed in a container - the current jasper4 depends on few servet2.3 calls, easy to substitute with old ones and make it run in 3.3. The only problem is 'disabling' the JSP1.2 functionality - i.e. have a setting to request it to throw exception if it detects a feature that shouldn't be used. This will be usefull for jsp1.3 as well - if you want to use a single codebase for all jsp versions.
