BTW, 'Bug' is bugzilla related name, in JIRA - this one called by 'Issue'. In ClearQuest this one is 'CR'.
Thanks for the observation - that's a good point. In Deskzilla we call this things "artifacts"

They are translated into "bugs" on the UI right now, but we'll have to change that once we have the second integration plug-in.

And one more, ClearQuest has Perl API, but have not Java API. The way to import issues - is Perl scripting with some schedulers, i think so.
Well, Bugzilla does not have any API whatsoever! And yet we get the bugs from it
I'm afraid that to use Perl scripts to synchronize bugs may be not the best way (remember, this is not a one-time activity - you need to download/upload bugs all the time). It might require a lot of things to be done by the user.
I thought CQ had a web-based interface. Is it possible to integrate with it by emulating user activity via HTTP?
Cheers,
