The fact is that you are starting cmd. Just because you can't see it doesn't mean it doesn't start.

If you want to see the output from the application, you need to get the outputstream (see Process for details). If you want to start cmd in a new window you can execute the string "cmd.exe /c start cmd.exe" instead, as in

Runtime.getRuntime().exec("cmd.exe /c start cmd.exe");

Try checking the file permissions for iexplore.

Allow execute privileges for all processes/users , if not set already.
