execute unix command using java

I tried what you said. But its not working and returning error message,

java.io.IOException: CreateProcess: ls -a error=2

at java.lang.ProcessImpl.create(Native Method)

at java.lang.ProcessImpl.<init>(Unknown Source)

at java.lang.ProcessImpl.start(Unknown Source)

at java.lang.ProcessBuilder.start(Unknown Source)

at java.lang.Runtime.exec(Unknown Source)

at java.lang.Runtime.exec(Unknown Source)

at java.lang.Runtime.exec(Unknown Source)

If i try this statement,

Runtime.getRuntime().exec("c\windows\notepad");

It is working fine.

Any idea about this.

Plz ...........
