In some environments, your application may need to connect through a proxy server, for example, if your application accesses an external resource such as a Web service. At a minimum, your application needs to provide the following connection information when you invoke the JVM if the application connects through a proxy server:
Server name or IP address of the proxy server
Port number on which the proxy server is listening for HTTP/HTTPS requests
In addition, if authentication is required, your application may need to provide a valid user ID and password for the proxy server. Consult with your system administrator for the required information.
For example, the following command invokes the JVM while specifying a proxy server named pserver, a port of 808, and provides a user ID and password for authentication:
Alternatively, you can use the ProxyHost, ProxyPort, ProxyUser, and ProxyPassword connection properties, but these properties are applied only for the first connection. See Using Connection Properties and Proxy Server Properties for details.
