I solved this problem by giving full path to mysqldump.exe

You can get SO environment variables by

Map env = System.getenv();
final String LOCATION = env.get("MYSQLDUMP");

I setup the system variable like this :

• Variable Name : MYSQLDUMP
• Value : D:\xampp\mysql\bin\mysqldump.exe

Now just execute this code below,

String executeCmd = LOCATION+" -u " + DBUSER + " --add-drop-database -B " + DBNAME + " -r " + PATH + ""+FILENAME
Process runtimeProcess = = Runtime.getRuntime().exec(executeCmd);

Note : If you don't have configured password for mysql server just remove the -p PASSWORD attribute from the code. And don't forget to restart your computer after creating a new system variable.
