OSGi services start order in the OSGii service registry

Hi,

What is the start order of OSGi services in a service registry? Are they started by the bundle id or by alphabetical order?

Hi,

It's by the bundle start-level, from low level to high level.

I thought so too which lead me to do add my osgi bundle id to startup.properties by doing this:

com/company/division/system-service/3.0.0/system-service-util-3.0.0.jar=55

Except if this is not the right way to do this.

Hi,

No, the bundle specified in startup.properties should be the system level core bundles used by FUSE ESB, especially need to be loaded before Karaf feature service, users shouldn't add customer bundles into it. You can use features where you can use start-level attribute to specify a certain bundle start level.
