How to get information about the Server using Servlet |
|
|
These are the four methods that a servlet can use to get information about its server:
public String ServletRequest.getServerName()
public String ServletRequest.getServerPort()
public String ServletContext.getServerInfo()
public String ServletRequest.getAttributes(String name)
|
The sample code below uses the above function and print the server information to client.
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class DemoServerSnoop extends GenericServlet{
public void service(ServletRequest req , ServletResponse res)
throws ServletException,IOException{
res.setContentType("text/plain");
PrintWriter out= res.getWriter();
out.println("req.getServerName()" + req.getServerName());
out.println("req.getServerPort()" + req.getServerPort());
out.println("ServletContext().getServerInfo()" +
getServletContext().getServerInfo());
out.println("getServerInfo() name:" +
getServerInfoName(getServletContext().getServerInfo()));
out.println("getServerInfo() version:" +
getServerInfoVersion(getServletContext().getServerInfo()));
out.println("getServerContext().getAttribute(\"attribute\")" +
getServletContext().getAttribute("attribute"));
}
private String getServerInfoName(String serverInfo){
int slash = serverInfo.indexOf('/');
if(slash==-1)
return serverInfo;
else
return (String) serverInfo.subSequence(0,slash);
}
private String getServerInfoVersion(String serverInfo){
int slash = serverInfo.indexOf('/');
if(slash==-1)
return null;
else
return serverInfo.substring(slash + 1);
}}
