UUID MAC configuration

[Pradeep Arumalla]

hi all,
I am using VersionOneGenerator  and I see that we need to configure the MAC
addres in the xml file , I mean the uuid.state file .It works locally .But
how do I give to other teams and ask them to work without having to enter
the MAC address in the uuid.state file.I mean is there any better way to
detect the MAC address automatically ?  *My Idea is to give a jar file to
different teams in my company to  generate UUID's. *

Thanks

UUID number generation problem

[Pradeep Arumalla]

hi all,
 I am trying to understand how the UUID generation works, I am trying to
run the *code snippet 1  *,100 times, and it prints the same number 100
times, Is it not supposed to print a different number eachtime.And If I run
the *code snippet 2  * 100 times, I get adifferent number each time .The
documentation says *code snippet 1*   is efficient than *code snippet
2.  ,*forgive my ignorance
*.* Please help
**
**
**
**
*code snippet 1 :*
**
for ( int i=0; i100; i++){
  System.out.println(***+ UUID.nameUUIDFromString(namespace,new
UUID(f807f2fc-b49b-4512-a787-92300367b932),UUID.SHA1_ENCODING));
 }


*code snippet 2 :*
**
for ( int i=0; i100; i++){
  System.out.println(*** +UUID.randomUUID().toString());
 }

Thanks

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());

commons id package code issue

[Pradeep Arumalla]

Hi all,
 I am trying to downloadthe commons id package found at
http://jakarta.apache.org/commons/sandbox/id/ , and write java program for
generating  UUID's , but how do I get the code ? jar , zip ?  It takes me to
a folders page , I guess I need to  download from a repository ? , can some
body point me in the right direction. Sorry for sending personal mail, I
tried sending it to the groups , but not sure it went through.


Thanks
Pradeep
