Hi
I am using a FileContext with a LoaderEngine to set the 'root' of the
web server.
FileContext context =3D new FileContext(new File("webserverroot/"))=
;
LoaderEngine engine =3D new LoaderEngine(context);
This works just dandy.. but I would like to support the concept of
multiple server roots...
Do I have to rewrite the LoaderEngine to accomplish this?
LoaderEngine engine =3D new LoaderEngine();
engine.addContext(new FileContext(new File("root1"));
engine.addContext(new FileContext(new File("root2"));
Also.. would be nice if the resolver tried to resolve in root1.. then
root2.. then fail..
Any help would be much appreciated..
Thanks!
Brian

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.

I have thought of doing similar thing, but what in my mind is to
extend java.io.File() object (which is not final) which accepting
multiple files at constructor, then overload approach method, like
list() and listFiles() . I think this should work
