[Jython-users] Can't run java.lang.Runtime.getRuntime().exec("cmd....")

[Alec C. <ale...@me...>]

G'Day

Jython 2.1 on Windows 2000 SP3. JDK 1.4.1_1

I am trying to execute a command from within a Jython script and 
failing. The snippet below shows the problem I am seeing. I have tried 
various different approaches and failed. The only thing I can think of 
is that the Java security manager is stopping this perhaps??? How would 
I find out or fix it?

Many thanks



 >>> from java.util import Random
 >>> r = Random()
 >>> r.nextInt()
1416976808
 >>> from java.lang import Runtime
 >>> java.lang.Runtime.getRuntime().exec("cmd.exe /cecho hello")
Traceback (innermost last):
   File "<console>", line 1, in ?
NameError: java
