I dont' quite understand the signedjar stuff? Isn't this in a serverside
application?
At any rate, I went through a similar nightmare on NT.. Turns out that if
my app is running in turbine as part of Tomcat running as an NT service,
then all my commands need a "cmd /c dir" before them. Not running as NT
Service, then "dir" would work!
Also, I had to make Tomcat run not as the localsystem, but a network account
with better permissions. I know you are on linux, but hopefully this might
give you ideas!
Also, I copied from some great code from cruisecontrol's Ant interface class
to get back output:
import net.sourceforge.cruisecontrol.util.StreamPumper;
<snip>
Process p = Runtime.getRuntime().exec( getCommandLineArgs(
buildProperties ) );
StreamPumper errorPumper = new StreamPumper(
p.getErrorStream() );
StreamPumper outPumper = new StreamPumper( p.getInputStream()
);
new Thread( errorPumper ).start();
new Thread( outPumper ).start();
InputStream input = p.getInputStream();
p.waitFor();
The StreamPumper class is available from CrusieControl's site. However, in
the Jar file I downloaded, I could not find it, but in CVS it is there.
Works great!
Also, look at how AntServlet in the Scarab project works.. I use it as
well...

You need set system permission (signed jar o cab file) before to call
Runtime
for Explorer
try {
PolicyEngine.assertPermission(PermissionID.SYSTEM);
PolicyEngine.assertPermission(PermissionID.EXEC);
Runtime.getRuntime().exec( " command " );
}
catch(Exception e) {
System.out.println(" Don�t could to launch App " + pathApp);
}
for netscape
PrivilegeManager.enablePrivilege("UniversalExecAccess");
try {
Runtime.getRuntime().exec("command " );
}
catch(Exception e) {
e.printStackTrace();
}

Don't you need to capture the Process and then read the output from its
InputStream?

hi,
I need to run a linux command from my Index.java file but when I write :
Runtime.getRuntime().exec("rm -rf path-to-dir");
nothing happens and no Exception is thrown.
what's wrong ?
thanks for answers
