Java app behind proxy to use http_proxy variable in linux

Question

I am thinking of a simple Java appplication (command line) that connects to the internet to download a XML file, the problem is that my Ubuntu is using a proxy to connect to internet with username and password (through http_proxy ="http://<username>:<pwd>@<ip>:<port>" ). So my question is, could it be possible to write a java app to use http_proxy variable? Instead of programmatically setting http proxy and host in every app I will write.

Answer 1

Don't forget the shell variable _JAVA_OPTIONS

export _JAVA_OPTIONS='-Dhttp.proxyHost=cache.com -Dhttp.proxyPort=3128'
