Forward( ) : javax.Servlet.RequestDispatcher interface. - RequestDispatcher.forward( ) works on the Server. - The forward( ) works inside the WebContainer. - The forward( ) restricts you to redirect only to a resource in the same web-Application. - After executing the forward( ), the control will return back to the same method from where the forward method was called. - The forward( ) will redirect in the application server itself, it does'n come back to the client. - The forward( ) is faster than Sendredirect( ) . To use the forward( ) of the requestDispatcher interface, the first thing to do is to obtain RequestDispatcher Object. The Servlet technology provides in three ways. 1. By using the getRequestDispatcher( ) of the javax.Servlet.ServletContext interface , passing a String containing the path of the other resources, path is relative to the root of the ServletContext. RequestDispatcher rd=request.getRequestDispatcher ("secondServlet"); Rd.forward(reque...

1. Use maven API - DefaultArtifactVersion class import org.apache.maven.artifact.versioning.DefaultArtifactVersion; DefaultArtifactVersion minVersion = new DefaultArtifactVersion("1.0.1"); DefaultArtifactVersion maxVersion = new DefaultArtifactVersion("1.10"); DefaultArtifactVersion version = new DefaultArtifactVersion("1.11"); if (version.compareTo(minVersion) == -1 || version.compareTo(maxVersion) == 1) { System.out.println("Sorry, your version is unsupported"); } 2.

Reboot Reboot, then delete. DEL or RMDIR Open a command line window (WindowsKey + R, enter: cmd). Move to the folder in question by means of CD commands like CD \ and CD foldername. Delete the file or folder by using the DEL command to delete files or the RMDIR (remove directory) command to remove directories (folders). Kill explorer.exe If this, on its own, is still not enough, then leave the command line window on the desktop, open Task Manager (Ctrl + Shift + Esc), and kill all explorer.exe tasks. Your desktop will go blank, except for the windows already open. Now try to delete the offending file by means of the DEL command, or folder by means of the RMDIR (remove directory) command, in the command line window, as described above. After that, in the command line window enter: explorer to restart your desktop. If you closed the command line window, you can still restart explorer by opening the Task Manager by holding down the Ctrl and Shift keys and briefly p...
