Hi. I'm using my application on networks that have proxy, and others that do
not.
I'm trying to make a ProxySelector that will use the System proxy setting as
default (just pass the select request to the delegate), and if that fails,
showing a dialog to configure the proxy for this application ins
I've just realized that i could have explained this much more cogently by
just saying: "I want to detect if i'm behind a proxy firewall".
I'm thinking of using:
InetAddress address = InetAddress.getByName("http://google.com";);
if (address.isReachable(2000)) {
//yes
}else{
//no
}
but even google
Anyone read the first message at all? The problem is that other proxy
requests are effectively ignored after a DIRECT connection even if it fails.
What i am trying right now is implementing ProxySelector so that a "manual"
proxy configuration is added at the end of the
public List select(final URI
But it's completely unintuitive! I can't know if i need to bother the user
about proxy configuration before trying with no proxy, but trying to use
that disallows the use of any other.
Trying to wrap Proxy.NO_PROXY to circumvent that, even if technically
possible, just makes the code fail in the n
Test case:
package util.net;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.Proxy;
import java.net.ProxySelector;
import java.net.SocketAddress;
import java.net.URI;
import java.net.URL;
import java.net.URLConnection;
import java.util.Collections;
import java.
The problem is that the proxyselector is being called at all. I have a real
use case where i use the proxy selector to request proxy information for the
user. To do that i have to make a (very dirty) url connection to a set of
sites one of which i assume to be always up.
This is recursive. To avoid
What i mean too is i expected the User given proxy selector to be the
default "then".
After all the ProxySelector installation call is
ProxySelector.setDefault(userProxySelector);
Besides sending a Proxy to the connection should mean that the connection is
going to use that proxy if any? Why ask the proxy selector anything?

The problem is that the user (or any really) proxyselector is being called
at all
Huh?
But it throws StackOverflowError. after installing UserProxySelector and
calling any method. Just to be clear it is the right class, it is attached.
My java version:
E:\java\bin>java -version
java version "1.6.0_14-ea"
Java(TM) SE Runtime Environment (build 1.6.0_14-ea-b04)
Java HotSpot(TM) Cl
ProxySelector) so it shouldn't recurse so
no StackOverflowException.
Saving the original proxy selector is just not to affect any other tests.

Hi. I have a ThreadPoolExecutor that is using a thread factory that creates
deamon threads.
On these threads i do ImageIO.read(someURL).
On a dual core machine i'm seeing hangs when i close my application and the
JVM is in the
ImageIO.read(URL) (i think on native code).
My rationale is the follow
Correction. Not all tcp connections appear to need to be in CLOSE_WAIT in
case of hang. I just tried again with the processor affinity set to 1
processor and i saw two established connections.
Also i noticed something. jps (and netbeans when debugging - but it still
hangs) think that the process is finished while the windows
taskmanager/process explorer shows it still.
This would appear to be consistent with not being able to get a thread dump.
This is a very strange state for a program
I believe i have isolated this, and it is in my code sorry:
Apparently my ThreadPoolExecutor subclass misbehaves when the queue is full
of pending tasks and a shutdown (by system.exit or normal termination of all
windows) occurs, even if the threadfactory it uses marks the threads as
daemon threads
I have a mapping from uri to real files, and to i was hoping to use that
constructor to do the work, however it says it only accepts,
"absolute, hierarchical URI with a scheme equal to "file""
Now, many times on html files the uri would be the second notion of
hierarchical from the javadoc
"A *h
Yes, they are relative to the current directory of the file normally (the
current dir won't work since the file might not be there).
I was just surprised at the inflexibility since the file: scheme is not used
on the net. I understand that trying to convert from relative (without
scheme) to file i
That's not what i meant. Relative to the "parent directory of the file".
Which may be anywhere.
