Hmm, the nice thing about open source is that you can bend it to your own
requirements. So, no, I don't think you are any missing anything, and yes,
it's a good enhancement.
I recommend that you raise a ticket and - if you like - attach a patch with
your preferred solution.
Looking at the code myself, I see:
public class IsisWebAppBootstrapper implements ServletContextListener {
...
public void contextInitialized(final ServletContextEvent
servletContextEvent) {
try {
final ServletContext servletContext =
servletContextEvent.getServletContext();
final String webappDir = servletContext.getRealPath("/");
final String webInfDir = servletContext.getRealPath("/WEB-INF");
loggingConfigurer.configureLogging(webInfDir, new String[0]);
// will load either from WEB-INF or from the classpath.
final IsisConfigurationBuilder isisConfigurationBuilder =
new IsisConfigurationBuilderResourceStreams(
new ResourceStreamSourceForWebInf(servletContext),
ResourceStreamSourceContextLoaderClassPath.create());
...
}
}
Actually, with the current impl, it would seem that you could just build a
JAR with your resources and add it to the classpath. But I don't think
that's quite what you want.
So, I reckon instead that you want a way to provide another
ResourceStreamSource, probably
org.apache.isis.core.commons.resource.ResourceStreamSourceFileSystem. The
location of the directory to load could be read from context-params.
Something like
final String configDir =
servletContextEvent.getServletContext().getInitParam("config-dir");
final ResourceStreamSource extraRss
= ResourceStreamSourceFileSystem.create(configDir);
and then use in the constructor of IsisConfigurationBuilderResourceStreams,
