Subject: [osgi-dev] Components are not started, although marked with
immediate=true
Date: Fri, Feb 17, 2017 2:46 PM
Hi,
I have a problem with immediate services and hoped that you guys
maybe can
help.
I'm currently trying to implement several services within one bundle
(see
below for code).
I have set all of them to be immediate (by immediate=true), but
still,
when I start the OSGi container with my bundle in it, only Con1,
InDataPort1 and OutDataPort1 are active. The rest is satisfied but
not
active according to felix.scr console output:
g! list
BundleId Component Name Default State
Component Id State PIDs (Factory PID)
[ 10] test.Con1 enabled
[ 0] [active ]
[ 10] test.InDataPort1 enabled
[ 1] [active ]
[ 10] test.OutDataPort1 enabled
[ 2] [active ]
[ 10] test.Process1 enabled
[ 3] [satisfied ]
[ 10] test.Thread1_1 enabled
[ 4] [satisfied ]
[ 10] test.Thread1_2 enabled
[ 5] [satisfied ]
Am I doing something wrong?
I assumed that all services should be started as soon as they are
satisfied.
Any advice is highly appreciated.
Kind regards,
Thomas
