sorry, can't answer specific Q on whether you can access datasource from generator. but it sounds like you are trying to uniquely ID rows in a database?
if so then the simplest way seems to be to use auto_increment fields and let the database handle it. or are you saying that that isn'y working - is this what you mean by "not supporting the database-generated id-numbers"? if so please say more about why its not working. what database? code sample? > -----Original Message----- > From: Roland Carlsson [mailto:[EMAIL PROTECTED] > Sent: Wednesday 27 October 2004 11:49 > To: TomcatUsers > Subject: GlobalNamingResouces used by other GlobalNamingResources > > > Hello again! > > Sorry to bother in this topic again but I need to strait out > one more thing. > > I have my Datasource now as GlobalNamingContext (and a big > post-it saying > that I shall change the resource-link from DefaultContext). > > Since JDBC doesn't generate id-numbers and not supporting the > database-generated id-numbers I have written an id-generator > that takes care > of the problem.
