In order to work with a proxy, your Java application needs to specify information about the proxy itself as well as specify user information for authentication purposes. These properties appear to be undocumented, and are whispered between programmers as part of the Java folklore. The secret to combining Java and proxies lies in activating certain system properties in the Java runtime. Fortunately, Java makes it easy to work with proxies - if you know the magic words, that is.
While Java makes it easy to write Internet clients, these clients are useless unless they can get past your proxy. Proxies help reduce outside security threats while still allowing internal users to access Internet services.

To address this problem, network administrators often install something called a "proxy server." Essentially, a proxy is a service that sits between the Internet and the internal network and manages connections between the two worlds. The unfortunate side effect of this tactic is that internal users can't access external Internet servers, like Yahoo or JavaWorld. If the bad guys can't connect to any of your machines, they can't hack into them. One common security measure is to completely disconnect the corporate network from the Internet. Almost every company is concerned with protecting its internal network from hackers and thieves.
