Have a look at the documentation here:
http://jakarta.apache.org/commons/sandbox/id/uuid.html
The test cases in the src/test directory might also be useful.

Hi all,
below is what I am trying to do and see if it generates a unique
Id everytime I run in a loop, and I get this exception.I know there
should
be a file with java -d option *"
org.apache.commons.id.uuid.config.resource.filename" ,* but what should
the
file contain.Please help, if any body has done this before.
UUID ns = UUID.fromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8");
System.out.println("******* "+ns.timeUUID());
