Question

I have a struts 2 (jsp) web application with MySQL database.

Is it possible to take database backup from jsp/java page?

Is it possible to restore in the same way?

Please give me some tutorials or tips..

My actual need is to give a access to admin to take back up and restore it using gui itself, without accessing MySQL from server.

Thanks in advance..

If you are using mySQl you can do something like

   static int BUFFER = 10485760;      

public static String getData(String host, String port,    String user, String password, String db) throws Exception {

Process run = Runtime.getRuntime().exec(
           "C:\\Program Files\\MySQL\\MySQL Server 5.0\\bin\\mysqldump --host="  + host + " --port=" + port + 
           " --user=" + user + " --password=" + password +
           " --compact --databases --add-drop-table --complete-insert --extended-insert " +
           "--skip-comments --skip-triggers "+ db);
InputStream in = run.getInputStream(); 
BufferedReader br = new BufferedReader(new InputStreamReader(in));
StringBuffer temp = new StringBuffer();
int count;
 char[] cbuf = new char[BUFFER];

while ((count = br.read(cbuf, 0, BUFFER)) != -1)
         temp.append(cbuf, 0, count);

 br.close();
 in.close();

 return temp.toString();
}

public static void main(String[] args) {
byte[] data = BackupRestore.getData("localhost", "3306",
    "root", "", "test").getBytes();     
File filedst = new File(path);
FileOutputStream dest = new FileOutputStream(filedst);
dest.write(data);
}

But i believe until you have not any compelling/fancy reason to do this better user command line tools

You can use GUI tool being shipped with MySQL,more tested and more easy to use.

String path="C:/datadump/db_backup.sql"

make sure that path C:/datadump should exist or you can provide any other path of your choice.
