[jboss-dev] Migrating to JBoss Web 3

Hi, As part of the Servlet 3.0 development, AS trunk will have to be switched to JBoss Web 3. Most is just a one time API change that is not very difficult, and it should provide the same level of functionality than JBW 2.1 (the new features need many deployer updates), but the JSP changes are more intrusive. Of particular interest is the new handling for tag library descriptors, where instead of having Japser parse them "magically" (and in a very hackish way ;) ) parse them, metadata will have to be created in the container (Stan in particular asked for that ;) ). For example, for JSTL and JSF, some deployer or listener could be processing their taglibs using the new metadata classes and add them to the Tomcat deployer as "shared" taglib metadata, which would then be added to every webapps. This could be done by with the service that would be looking for ServletConteainerInitializers in shared libraries. Given the amount of stuff that is involved, I don't see how to do the thing in one pass, so I was posting to inquire about the development strategy. Should this be done in trunk, accepting that JSP taglib support is not going to be functional for a little while ? [note: it might be possible to hack in a temporary solution by using Catalina's taglib processing for now] In a separate branch of AS ? (but given the rate of change, merging could be very difficult) Comments ? Rémy
