how to call a javascript file from a servlet?

[Ryan Gaffuri]

I would prefer not to include my javascript in my servlet. its too
messy. I am using j avascript to check for form errors(such as nulls
in fields). anyway to put my javascript in a seperate script and call
it from my servlet?

What do you mean including javascript in your servlet? The javascript
code in the response?

If so, I use JSP's, and just include the file there...

The output of a Servlet is a simple HTML page, so once it's delivered to
the client it has all the limitations and capabilities of one, including
the ability to refer the separate JavaScript files with the src attribute
of the script tag.

Servlets run on the server. JavaScript runs on the client. You cannot
call a function on the client from the server.

Please tell me you're not using *only* javascript to test for form
errors... Please tell me everything is being double-checked sever-side,
too.

Never rely on client-side validation of data.

And rather than questioning the overall design, the answer to your question
is, Yes, you can call JavaScript from your Servlet.

Netscape/Mozilla has the Rhino JavaScript interpreter written in Java which
is actually quite nice. You can embed the interpreter into your servlets and
it will run JavaScript for you.

It will NOT, however, have access to the actual HTML form page (as that's in
the browser), but it will run JavaScript from a Servlet.
