Proxy setting in TRKD API using Java

This
article describes configuration of a proxy server for Java.

In
order to configure a proxy server for a Java application you should set up the
following system properties (seearticleon Oracle site for additional
details):

For HTTP traffic:

http.proxyHost(default: <none>)

The host name, or
address, of the proxy server

http.proxyPort(default: 80)

The port number of the
proxy server.

http.nonProxyHosts(default: localhost|127.*|[::1])

Indicates the hosts
that should be accessed without going through the proxy. Typically this defines
internal hosts. The value of this property is a list of hosts, separated by the
'|' character. In addition the wildcard character '*' can be used for pattern
matching. For example -Dhttp.nonProxyHosts=”*.foo.com|localhost” will indicate
that every hosts in the foo.com domain and the localhost should be accessed
directly even if a proxy server is specified.

For HTTPS traffic:

https.proxyHost(default: <none>)

The host name, or
address, of the proxy server

https.proxyPort(default: 443)

The port number of the
proxy server.

Note:The
HTTPS protocol handler will use the same nonProxyHosts property as the HTTP
protocol.

You can use two main
approaches how to set environment variables in Java applications (the following
examples assume your proxy server host is "localhost" and port is 8888):

Command
line option when invoking the VM:

jre
-Dhttp.proxyHost=localhost -Dhttp.proxyPort=8080 myApp

jre
-Dhttps.proxyHost=localhost -Dhttps.proxyPort=8080 myApp

Using theSystem.setProperty(String,
String)method, assuming that
you have permission to do so:

System.setProperty("http.proxySet",
"true");

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

System.setProperty("http.proxyPort",
"8888");

System.setProperty("https.proxySet",
"true");

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

System.setProperty("https.proxyPort",
"8888");
