| Re: [p2-dev] Automated bundle installation and startup without platform restart |
So far, I've got an IApplication implementation that successfully works through Step #5. However, everything after Step 5 is giving me problems. As you know, the p2 logic only installs the IUs. It doesn't start the plugins, much less make their extension points available for creating executable extensions.For this to happens means that the bundles you are installing are not the same than those that you have been running since step #2. I understand that the point is to try to have a new application running, but what I'm getting at is that the installation of your application is causing a new version of the runtime (and maybe other bundles) to be brought in. Consequently, when you invoke applyConfiguration() on simpleconfigurator, the runtime bundles are stopped and uninstalled to get the new ones to run. The easiest way to know if this is really the problem is to look at the content of the bundles.info before and after the install and see if some key bundles like runtime, osgi, equinox.app, and friends have not changed. simpleconfigurator does not do anything fancy, it just makes sure that all the bundles and only those listed in this file are indeed installed in the fwk and started accordingly. One side note, from what I understand or your system, I would say that you may even want to ensure that the "management" application (the one that installs the other apps) and all its dependencies are not changeable since otherwise the install of an app could actually cause your management to be restarted while it is installing the new one :) HTH Pascal
