Cant find filepaths when blank space in folder name?

[Tomas]

Hi,

I have an java application that can launch windows files with theese code
lines that a nice person here provided me with:

public static final void openFileAndExecuteAssociatedApplication(String fullPathAndFileName)
{
try
{
Process p = Runtime.getRuntime().exec("cmd /c start " + fullPathAndFileName);
p.waitFor();
}
catch (Throwable ex){ex.printStackTrace();}
}
But if there is blank spaces in folder names(i.e e:\my files\test.txt)) the
system cant find the file and gives this errormessage:

"Cannot find the file 'e:\my'...."
Any suggestions how to solve this issue?

Regards
/Tomas

Yep. The Runtime.exec(String) method provides some very primitive
command line parsing, as described in the specification of the method
from the API docs. That parsing always breaks a command line into
separate parameters at the spaces. If you want something more advanced,
use the Runtime.exec(String[]) variant of this method, passing each
command separately. Looks like this:

Process p = Runtime.getRuntime().exec(new String[] {
"cmd", "/c", "start", fullPathAndFileName });

You can try to enclose fullPathAndFileName with " symbols :

Process p = Runtime.getRuntime().exec("cmd /c start \"" +
fullPathAndFileName + "\"");

No, you can't. It will still split at the spaces.

See Chris' reply.

use the version of exec where you do the parsing and pass an array of
strings for the parms.
