I haven't seen use of UUIDs (GUIDs) per http://www.opengroup.org/dce/info/draft-leach-uuids-guids-01.txt for js unique id's. I use them whenever I need truly unique (even cross system) identifiers. Windows clsid is a UUID. UDDI etc ... they're used in many applications and look like: ex: E00A4490-C7E0-11D7-8CAB-C94877403D5C (always 36 char when string representation)
I'd like to recommend adopting UUID use where applicable, if I may? Or perhaps they are in use in js... I just haven't seen them. I prefer uuid to rmi.uid. If it helps: UUID code from axis csv: http://cvs.apache.org/viewcvs.cgi/xml-axis/java/src/org/apache/axis/componen ts/uuid/ Package summary http://dwdemos.dfw.ibm.com/wstk/common/wstkdoc/axis/docs/apiDocs/org/apache/ axis/components/uuid/package-summary.html I was working with the WebPagePortlet2 and I was looking for a class such as org.apache.axis.components.uuid.SimpleUUIDGen in the js org.apache.jetspeed.util directory but didn't see one. Perhaps this could be added if it will be used else where? -----Original Message----- From: Luta, Raphael (VUN) [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 05, 2003 10:13 AM To: 'Jetspeed Developers List' Subject: RE : RE : RE : [J2] New Page API committed to CVS Right now, I'm simply using JetspeedIDGenerator, which We may possibly extend to provide "scoped" unique ID, like: getPortalUniqueID(String seed) to get a guaranteed unique portal-wide ID using the provided seed. We could also have: getUserUniqueID(User user, String seed) And so on...
