Re: [virgo-dev] Starting bundles automatically using plans

[Dmitry Sklyut <dmitry@xxxxxxxxxxx>]

Florian,

I think with something like HttpService you will get better results by adding it to the list of baseBundles of userregion.

$ cat $VIRGO_HOME/config/org.eclipse.virgo.kernel.userregion.properties 

baseBundles = \

 file:lib/kernel/org.eclipse.virgo.kernel.userregion-2.1.0.M06-incubation.jar@start,\

 file:lib/kernel/org.eclipse.virgo.kernel.osgicommand-2.1.0.M06-incubation.jar@start

 ... add your jetty http service here.

This will free you from having to play with the plan and manual start.

This causes modification to the config...  

Just a thought

Dmitry

I used a fresh installation to reproduce the STARTING scenario. Same result...the logs capture the following steps

step 1 - install Virgo Kernel and put bundles and plans into repository/usr
step 2 - start Virgo Kernel
step 3 - restart after enabling the OSGi console
step 4 - manually start HttpService
step 5 - shutdown

Looks fine to me.

But....things change when i tried the following workaround: A bundle starting all available bundles in the OSGi container (http://equinoxosgi.org/): org.equinoxosgi.core.autostart

step 6 - add autostart bundle to repository/usr
step 7 - add autostart bundle to plan in pickup directory

After a lot of Exceptions during redeployment: (@see 2nd serviceability.zip) everything seems to be in place now:
