I have looked at Seva's code and it doesn't produce any errors on my

of his index.py. and it's located in the examples/seva/ sub-directory
of my web root.
I am using an apache server (Xampp for Windows). Is the problem
something to do with the way he is serving using server.py. He is not
by any chance serving index.py, I suppose? Would that cause the
observed problem?

I think I know why this is working for you:
You are using apache, configured in such a way, so it gives access to
the whole file system, and by absolute path.
If you will try to use server.py, which I provided in the example, you
will see the problem: you need to make entire file system paths under
server catalog:
-------
$ ./server.py
localhost - - [25/Apr/2012 11:10:26] "GET /public/index.html HTTP/1.1"
200 -
localhost - - [25/Apr/2012 11:10:26] code 404, message File not found
localhost - - [25/Apr/2012 11:10:26] "GET
/home/seva/pyjamas/library/pyjamas/ui/public/tree_white.gif HTTP/1.1"
404 -
localhost - - [25/Apr/2012 11:10:26] code 404, message File not found
localhost - - [25/Apr/2012 11:10:26] "GET
/home/seva/pyjamas/library/pyjamas/ui/public/tree_closed.gif HTTP/1.1"
404 -
------
As you see, I have to make paths like
home/seva/pyjamas/library/pyjamas... under server's catalog for this
to work. (I have pyjamas installed in my /home catalog).
So, as I understand, we have currently two options for pyjd:
1. configure web server so it serves all file system, under absolute
paths.
2. recreate full file system paths under public/ catalog.
In both cases we have different environment in pyjd and pyjs:
In first case, it is bad to make all file system available for
production code.
I second case, your public/ catalog must look different for pyjd and pyjs.
I do not like either of the options :)

Seva,
Yes, I see your point. I have now run my modified version of index.py
with your server and it does indeed report 404 file not found errors, in
my case only for /public/tree-closed.gif, because of the extra nodes
I've added.
However, the actual display produced shows the images and they are being
obtained from pyjamas/library/pyjamas/ui/public (it makes no difference
whether they are present in /public/ or not). The application is
reporting no errors - only the server. And the errors are, in a sense,
spurious, because the application can obtain the images without doing an
HTTP call to get them. There should be a work-around that can handle
that. Pause for thought :).
