Re: [Simpleweb-Support] Multiple File Roots

[Niall G. <gal...@ya...>]

Hi Brian,

No, you do not have to rewrite the LoaderEngine to do
this. What you can do is extend it in much the same
way as the MapperEngine does. If you wish to add
multiple paths to the classpath used by the loader
engine then you can delegate to the following
constructor.

LoaderEngine(Context context, URL[] codebase);

Simply add additional URLs in the form
file:///a/b/c/path, etc. If you would like the Context
to find files from multiple roots, then you should
consider using the Locator. The locator performs a
search for files from multiple locations. I typically
use this for loading configuration files. The
simple.http.serve.FileLocator is good for this. For
example you could use:

Locator loc = context.getLocator();

loc.getFile("/my/file.txt");

The file is searched for within all roots specified to
the FileLocator. To increase the number of roots you
can do the following:

new FileLocator(new File[]{new File("root1"), new
File("root2")});

Also you will have to extend the FileContext like
follows:

class MyFileContext extends FileContext {

   private Locator loc;

   public MyFileContext(File base, Locator loc) {
       super(base);
       this.loc = loc;
   }

   public Locator getLocator() {
     return loc;
   }
}

Hope this helps.

Niall
