hi,
your browser tries to download the servlet's

is it possible that the server you're using
doesn't support servlets?
Its Tomcat with
apache
use the security features that have been around with servlets for ages -
HTTP basic auth, etc. a reading of the servlet spec should give you enough
info. above and beyond that, individual servlet containers (especially
commercial ones like weblogic, websphere) have extensions to that security
mode

Solution: use Netscape or Mozilla... ;-)
Sorry, I couldn't resist. AFAIK IE has never supported server push, from
the earliest days. I never heard any explanation of *why* they didn't
support this. The best you can do with IE is use browser refresh (with a
META refresh header, for best compatibil

These are not "packages" and commenting any extraneous imports would do
nothing to your program except debilitate it. Java imports are similar of C
#includes. The Java Runtime Engine picks only those classes you have

I commented out the import java.util.* and import java.text.* packages.
I left these alone:

That's all and compiled and I could see my simple output.

I did this about a year ago with SMIL, but I don't
remember how. I think it involved using the applet's AppletContext
class. This gives you access to the DOM which spawned the applet.
Check out the API on this.
Cheers!

I try to use "server push" to have a servlet return several pages all in response to the same request. It works fine in Netscape, but it fails in IE. It's kind of painful. Anyone has some solutions or alternatives? I appreciate it.

Hi
Instead of putting the parameter in the link to the servlet you can put it in a hidden
input field in a form that you submit with the POST method, and catch it with
doPost(). That way it's invisible to the user; though it's not as safe as the sessions
approach that Michael Weller suggested
I personally find Tomcat4.x easier to set up. I am using it in a development
environment, debugging with JBuilder5, and using Cocoon2rc2. It has better
support for contexts and .war files among other things... I have had no
problems, although I am not in a live commercial environment...

Sounds like your best approach is to just fetch the raw bytes and send
them on, rather than try to parse the bytes into an Image and then
encode the Image back to bytes. If you want to make edits to the
picture, then the techniques in Chapter 6 will be handy (like on p. 181

hi,
why don't you simply work with the session mechanism provided by the servlet
api to keep a list of documents the current user may view or to keep
information about the user to check if he shall be allowed to view the
requested document.

We have it working for IE5.0
As for Netscape (4.7 & above) I think one of our team mates is patching
something up...
But anything that spans across html to applet involving Javascript (like
ours...)
gives the maintainers ( ie. humans like us ) headaches :<

First, to qualify myself, I am relatively new to java. I am a RPG programmer
by trade.
We have web application (purchased) that does it's own document distribution
that. However in our environment, we are somewhat modifying it to adapt to
our evironment, but let it handle the front end security.

Hi Javier,

For testing and debugging you may try this sketched approach (please
