Comment on Tutorial : Read from a COM port using Java program By Steven Lim

I am running it within NetBeans. I set a breakpoint at:

portlist=CommPortIdentifier.getPortIdentifiers():

I do F& and is shows:

public static SecurityManager getSecurityManager(){

   return security 

but security is null so portlist becomse null and the program ends.

Any idea how to get past this?

Thanks,
