I suppose that your problem is that you are running server somewhere in local network, so you get your IP in that network. However when you are trying to use online service that discovers your IP address your IP is the IP of your service provider’s router or something like this. Using request.getRemoteAddr() is correct. … Read more
I followed the solution in the following link, and it works fine: Access Spring beans from a servlet in JBoss public class MyServlet extends HttpServlet { @Autowired private MyService myService; public void init(ServletConfig config) { super.init(config); SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this, config.getServletContext()); } }
The average decent servletcontainer itself flushes the stream by default every ~2KB. You should really not have the need to explicitly call flush() on the OutputStream of the HttpServletResponse at intervals when sequentially streaming data from the one and same source. In for example Tomcat (and Websphere!) this is configureable as bufferSize attribute of the … Read more

You can use HttpServletRequest.getScheme() to retrieve either “http” or “https”. Using it along with HttpServletRequest.getServerName() should be enough to rebuild the portion of the URL you need. You don’t need to explicitly put the port in the URL if you’re using the standard ones (80 for http and 443 for https). Edit: If your servlet … Read more
Instead of using a ServletContextListener, use a HttpSessionListener. In the sessionCreated() method, you can set the session timeout programmatically: public class MyHttpSessionListener implements HttpSessionListener { public void sessionCreated(HttpSessionEvent event){ event.getSession().setMaxInactiveInterval(15 * 60); // in seconds } public void sessionDestroyed(HttpSessionEvent event) {} } And don’t forget to define the listener in the deployment descriptor: <webapp> … … Read more
I think I may know what is going on. In your working web.xml you have set your servlet to be the default servlet (/ by itself is the default servlet called if there are no other matches), it will answer any request that doesn’t match another mapping. In Failed 1 your /* mapping does appear … Read more
If you are using spring you can do the following: public static HttpServletRequest getCurrentHttpRequest(){ RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes(); if (requestAttributes instanceof ServletRequestAttributes) { HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest(); return request; } logger.debug(“Not called in the context of an HTTP request”); return null; }
If you do not want tomcat to show an error page, then do not use sendError(…). Instead use setStatus(…). e.g. if you want to give a 405 response, then you do response.setStatus(HttpServletResponse.SC_METHOD_NOT_ALLOWED); response.getWriter().println(“The method ” + request.getMethod() + ” is not supported by this service.”); Also remember not to throw any Exceptions from your servlet. … Read more
