According to Jetspeed's documentation you cannot just drop a WAR into the webapps directory [1]. You have to place it in the WEB-INF/deploy directory of the Jetspeed webpp and it will deploy it (re-write the web.xml and copy it into the correct container location). I'm not sure what tricks WebSphere and JBoss are doing but remember that there portals are specific to their servlet/J2EE containers so they likely are doing things outside of the specifications to hook into the deployment process and re-write the web.xml to add the servlets.

I do think Jetspeed's approach is an interesting approach to the problem since you don't need to run a tool on the portlet just know that you have to put it in a special directory.

I don't get this either. And its not even like it isn't possible: Websphere Portal, Jetspeed 2 and JBoss Portal all do not(!) require me to write a specific web.xml. I can export my webapp as a war file, deploy it to the server and use its admin tools (built as part of the portal GUI) to deploy the available portlets to one or more pages.

How hard can it be do simply parse the portlet.xml (that is done anyway) and create the necessary servlets (if at all) on the fly? I don't see why the container should even waste its resource by rewriting the deployed web.xml first, just to parse it again.

    Troy,

    What many portals do is provide some sort of portlet deployment tool.
    uPortal (which uses Pluto) does this. While it isn't as nice as just
    dropping the WAR into the webapps directory it does shield you from
    knowing what is going on with the web.xml or having to maintain it. I
    actually support keeping this web.xml magic as far away from the
    developer as possible. I have done some (cursory) looking into
    having a
    portal detect new web-apps and re-write the web.xml at deploy time it
    really seems like the portal would have to have hooks into the
    servlet
    container to catch the deployment of the WAR and re-write the web.xml
    before the container gets around to parsing it.

    There may be some options with just looking at the webapps dir
    every few
    seconds and updaing web.xmls as needed and counting on tomcat to
    re-load
    the changed app but that may not be the best approach since all of the
    webapps would get loaded twice.

    they aren't like normal J2EE apps where you code your application
    and drop your war file into any standard container and everything
    works as expected. Your application has to be customized for the
    container. Specifically, your web.xml has to be mangled to suit
    the container. For each container, you will have to maintain a
    separate web.xml. You will likely have to maintain multiple IDE's,
    build tools, etc., since everybody seems to insist on hiding the
    specifics of web.xml mangling behind development tools required by
    the container. It would be nice if the container would handle
    web.xml mangling instead of doing it at build time, but that seems
    to be difficult, as nobody does it that way.
