HttpClient and Applets
Hello,
I have an applet that has to communicate with the originating server
through HTTP. It has to send and retrieve custom data, through GETs and
(if possible) POSTs. I am using HttpClient (I am open for suggestions on
that), which works well in a direct connection. However, when I am
behind a proxy, I get a AccessControlException. I could explain this by
the fact that the proxy server is not the originating server, and that
by specification I am only allowed to contact the originating server.
But I really don't want to bother about things like proxies at all. What
I really want is that the Applet transparently hooking on to the browser
settings for the proxy. The only possibilities I see now to contact the
originating server Applet-wise is through Applet.getAudioClip(),
.getImage(), .getAppletContext().showDocument(), but none of this is
what I want.
I'm sure I'm not the only one who wants to do something like this.
There's probably either a simple solution or it's just plain impossible.
I hope to hear it either way.

My 2p: one very common access error over http in applets is that
host-names don't match exactly...

Jeroen,
The AccessControlException is thrown by the AccessController to
indicate that a requested access (to a critical system resource such as
the file system or the network) is denied. This problem has nothing to
do with HttpClient
You may want to take a look at the classes (below) to see how
a (limited) proxy setting auto-detection could be implemented:
http://svn.apache.org/repos/asf/jakarta/commons/proper/httpclient/trunk/src/contrib/org/apache/commons/httpclient/contrib/proxy/
Hope this helps
Oleg
