How can I get a the host name (with port) that a servlet is at

Question

I thought ServletContext might provide a method. Does the getAttribute() method of ServletContext provide any help i.e. is there an attribute name (maybe \"host\", \"port\")

Answer 1

The ServletRequest object that has been passed to your doGet, or doPost method has getServerName and getServerPort methods that provide this information.

eg

public void doGet(ServletRequest request, ServletResponse response) {
    System.out.println("Host = " + request.getServerName());
    System.out.println("Port = " + request.getServerPort());
}
