[p2-dev] FW: P2 Profile Questions
|
Hi
Folks,
Firstly, apologies if this has gone to the wrong
list. Let me know and I will repost
immediately.
I'm
considering refactoring the webapp quickstart code and submitting back to the
community. To that end I've started a discussion page
here:-
Before
I do this however I'd like to check that I understand p2 and that this is, in
fact, a required course of action for me.
My
understanding is that any 3.4 equinox application wishing to use p2 (as well as
including the p2 bundles) must establish a valid p2 profile around the initial
"bootstrap" application. Otherwise p2 wont provision at all or wont
provision properly. There are at least a couple of ways of doing
this:-
1.
Establish a p2 profile for the bootstrap application during the nightly build
and make it part of the application
2.
Establish a p2 profile the first time the application is started (the webapp
quickstart approach)
To
date I have attempted to go the first route. Briefly, I have a version
of the servlet bridge that I've modified to use a release version of the
ganymede codeline. I've manually updated the set of bundles to include p2,
the simpleconfigurator and simpleconfigurator.manipulator. I created a
basic profile for this installation by using the admin UI and using it to
provision a feature that contained all the same bundles as my initial
installation. I copied this profile into my application. I then
found that I had to add all the "tooling.*" installable units to this profile as
they were missing and this was causing provisioning issues.
After
these steps I've had some success provisioning other features and bundles from
updates site and by dropping them into the "dropins" folder.
So, I was happy I got it working :-)
But it seems a bit hokey process to me.
Perhaps I am doing it wrong? Or perhaps the webapp quickstart is actually
the right way of doing this? Or perhaps they are two ways of achieving the
same goal.
Would
love to hear anyone thoughts on the subject.
Many
thanks
_Paul
