    So I guess I'd need to extend 
    jvm_binary
    ? e.g. subclassing it or something?

    perhaps... i don't know think i understand the desired layout, and why it's a requirement

    Not sure how familiar you are with WAR files in general

    .war files are zip files containing .jar files plus metadata in a standard directory layout.

    You can also have an "exploded WAR," which is a directory containing the jars and metadata in the expected layout.

    When your directory/zip follows the standard .war format, you can ship the .war to a standard Java Web Application Server. Tomcat is the most popular, but there's also JBoss, as well as enterprise-y ones like IBM WebSphere

    Today, we use Maven's war plugin to build a war file; that's what we deploy to our Tomcat servers in production to run our Java code in a web server.

    I'm trying to port that Maven build to Pants. I've converted most of the projects straightforwardly, because they're just jars, but now I'm at the end trying to build a war so I can actually run my code.

    The war layout works like this: you can put any number of JSPs in the root directory of the war and/or subdirectories

    There's also a special blessed 
    WEB-INF
    subdirectory containing metadata

    The most important metadata file in that directory is the 
    web.xml
    file, which includes a bunch of details about how URLs should map to Java

    is WEB-INF generated or static?
  • b

    But the other key thing is that the 
    WEB-INF
    directory contains a 
    classes
    subdirectory, containing loose classes, and/or a 
    libs
    subdirectory, containing jars which are automatically available in the web application's classpath.

    @full-kilobyte-93429: The web.xml file is normally static (though I'm sure some people do generate it); it's easy to drop that file in the right place with 
    jvm_app
    bundles
    .

    But I'm stuck on the jars. They need to be in a 
    WEB-INF
    subdirectory.

    02/04/2016, 12:03 AM
    hmm, maybe I could symlink f rom 
    WEB-INF/libs
    to 
    ../../../libs
    ?

    Can I do that with 
    bundles
    ? Create a random symlink from one point in the bundle to another?
  • w

    witty-crayon-22786

    02/04/2016, 12:04 AM
    ...with the rest of the loose files included via bundles on a 
    jvm_app
  • w

    02/04/2016, 12:04 AM
    no, not via bundles currently. would either have to do it as a post-build step, or...?
  • b

    What's the normal way of running post-build steps?
  • w

    witty-crayon-22786

    02/04/2016, 12:05 AM
    ...or as a subclass i suppose.
  • w

    can install a task in the bundle goal to do it
  • w

    witty-crayon-22786

    02/04/2016, 12:05 AM
    but, honestly... just creating the symlink as you deploy would be less fragile.

    I hypothesize that the end result of my work will be a 
    war
    target type in Pants core, with a 
    WarCreate
    task that extends 
    BundleCreate

    Which is to say, creating wars is a pretty common requirement in Maven land

    I agree that a new task is the way to go for the WAR file creation. I think it would be a very handy feature for supporting servlet bases deployments.
