I would like execute the following command with Java: C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqldump -u

I would like execute the following command with Java:

“C:\Program Files\MySQL\MySQL Server 5.5\bin\”mysqldump -u root
–password=xxxx –routines database > C:\Users\john\Desktop\backup.sql

The command works perfectly when I use the Windows cmd.exe but not with my Java application.

cmd = "\"C:\\Program Files\\MySQL\\MySQL Server 5.5\\bin\\\"mysqldump
-u root --password=xxxx --routines database > C:\\Users\\john\\Desktop\\backup.sql
Runtime runtime = Runtime.getRuntime(); 
process = runtime.exec(cmd);

I got the following error:

“C:\Program Files\MySQL\MySQL Server 5.5\bin\”mysqldump -u root
–password=xxxx –routines database > C:\Users\john\Desktop\backup.sql java.io.IOException: Cannot run program “”C:\Program”: CreateProcess
error=5, Access is denied

Do you have any idea?

Thank you.

    Error 5 is either 1) cannot access the file/folder or 2) don’t have permissions.

    Looks like the space in your ‘Program File’ directory name may be causing trouble causing trouble. Check where it says “Cannot run program “”C:\Program”. This is obviously not a reference to the command you are trying to run. What I would do is add MySQL to your path and then just call the mysqldump command without the path to it. If you don’t want to do this, you can define a system variable and reference it with %MYSQL_HOME%\mysqldump.

    Once you have the path resolved, if this still doesn’t work, you’ll want to look at the permissions for the command. You’ll need to make sure that the process has permission to execute the command. I think this in local admin groups or something like that.

    Dollars to donuts its your path tho.
