proxy in java

[zeevgetner]

hi everybody,

i have a program that does http comunication.
my system administrator wants the program to comunicate throgh a proxy server. im tring to make the java environment use a proxy server.

one option that i tired is to use :
jave -DproxySet=true -DrpoxyHost=@@@ -DproxyPort=@@@ myclass
(@@@ are the actual settings).

why doesnt it work?

im using java 1.5 JRE is this a problem?

JRE 1.5 shouldn't be a problem:

Maybe you could write a test program using this:

Anyway, that error do you get?

Cheers,

im not getting an error,
it just doesnt use the proxy.

my system administratot monitors the network,
and my program doesnt try to use the proxy, but goes diractly to the ip-adress.

im hoping for a solution that does not involve aditional code.

why do you think m setting doesnt work?

I have no idea, I'd write a test program.

You may also want to consider using an Open Source library such as the Apache HttpClient to do your comms :-

http://jakarta.apache.org/commons/httpclient/

This is capable of going through a proxy and this feature is documented with the software.

tim (and also dian)

thank you for your help.

the problem i have with tim's idea,

is that i dont have all the sources of the classes
that do the comunication. they are writtne by a business asociate of the company i work in. so i nead a solution that is not based on code.

right now i have one solution that involve installing a program that ctransfer al the comunication to a proxy,
(and it works)

but i wish i found a way to have java work with a proxy.

As I suggested, write a test program, use your settings, debug it and maybe you can find why it's not working and apply it to your actual software.

Cheers,
Dian

You have :

-DrpoxyHost=@@@

but you want :

-DproxyHost=@@@

... and it will only work for the class HttpURLConnection - it will not work if you use java.net.Socket directly yourself.
