Java environment variables and system properties (including proxies)

Reference

Time Zone Settings in the JRE (Oracle jdk 9)

https://docs.oracle.com/javase/9/troubleshoot/time-zone-settings-jre.htm

System properties

user.timezone

You can explicitly set a default time zone on the command line by using the Java system property called user.timezone.

Eg: -Duser.timezone=Europe/Madrid

How-to make Java output messages in English instead of the default locale language

Set the environment variable JAVA_TOOL_OPTIONS, eg:

set JAVA_TOOL_OPTIONS=-Duser.country=US -Duser.language=en -Dhttp.proxyHost=%IPV4_ADDRESS% -Dhttp.proxyPort=3128 -Dhttps.proxyHost=%IPV4_ADDRESS% -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts="localhost|127.*|[::1]"

que un cop resoltes le varialbes quedaria, eg, així:

JAVA_TOOL_OPTIONS=-Duser.country=US -Duser.language=en -Dhttp.proxyHost=172.23.200.238 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=172.23.200.238 -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts="localhost|127.*|[::1]"

Java Networking and Proxies

Reference documentation for Java 8 at:

http://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html

Sample 1 (command line or JAVA_TOOL_OPTIONS environment variable):

-Dhttp.proxyHost=localhost -Dhttp.proxyPort=3128 -Dhttp.nonProxyHosts="localhost|*.uoc.es" -Dhttps.proxyHost=localhost -Dhttps.proxyPort=3128

Sample 2 (program):

System.setProperty("http.proxyHost", "localhost");

System.setProperty("http.proxyPort", "3128");

System.setProperty("http.nonProxyHosts", "localhost|*.uoc.es");

System.setProperty("https.proxyHost", "localhost");

System.setProperty("https.proxyPort", "3128");

Properties:

http.proxyHost

http.proxyPort

http.nonProxyHosts

https.proxyHost

https.proxyPort

ftp.proxHost

ftp.proxyPort

ftp.nonProxyHosts

socksProxyHost
