go to a specific directory (Runtime.getRuntime();)

[Peter Primrose]

Hi all,

Im trying to refer to a specific folder in my file system (yes, i know the path :-) )
for some reason when I use:

 Runtime rt = Runtime.getRuntime();
Process cd = rt.exec("cmd /c "+path);
cd.waitFor();
 

it doesn't take me to the specific folder.

the path in this example is: C:\Tomcat\webapps

anyone?

Are you trying to set the working (current) directory for the JVM process? You can't do that. But you really shouldn't need to -- what is your actual requirement?

[Peter Primrose]

I have a file there and I need to copy it to a different directory.

[Ernest Friedman-Hill]

Open it with a FileInputStream
Open the new location with a FileOutputStream
Allocate a byte array buffer
Read into the buffer, write from the buffer
close both streams.

I need to do it (the copy) with the DOS command.

The Runtime.getRuntime().exec() method is overloaded with a version that lets you set the current working directory.
