Calling Executables?  
Jun 17, 2004 6:32 AM

What ( if applicable ) is the easiest way to initiate an existing executable on a windows machine. For example, I would like to make a simple application that utilizes mysqldump.exe for backing up existing databases. This cannot be done through the JDBC as mysqldump is an .exe that runs external to mysql. If invoked through the command line, mysqldump can also take command line arguments to reference which database to back up and the location to store the .sql file. If anyone can steer me in any direction (even as far as tutorials to digest) it would be appreciated.

That's fine for calling an executable but how do I pass arguments to the executable?
Here is the command line syntax for using mysqldumb
c:\mysql\bin\mysqldump -u root dbname > c:\<file location>

System.getRuntime.exec() won't compile, but Runtime.getRuntime does
mysqldump -u root dbname > c:\<file location>");
does not do what I would like.
