Getting server address and application name

Question

Environment: NetBeans 6.9.1, GlassFish 3.1

I have a Java Web Application. How to get the server address and the application name dynamically? The '2in1' solution would be the best for me: http://localhost:8080/AppName/.

Is there a practical way to get that information?

Let's say the value of AppName will be fixed, so I only need the host address. Is it possible to retrieve it via JMX? Any other ways?

Answer 1

The HttpServletRequest object will give you what you need:

• HttpServletRequest#getLocalAddr(): The server's IP address as a string
• HttpServletRequest#getLocalName(): The name of the server receiving the request
• HttpServletRequest#getServerName(): The name of the server that the request was sent to
• HtppServletRequest#getLocalPort(): The port the server received the request on
• HttpServletRequest#getServerPort(): The port the request was sent to
• HttpServletRequest#getContextPath(): The part of the path that identifies the application
