Re: [equinox-dev] Autostarting required plugins

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

Not sure that this is quite what he
was looking for.  The Eclipse LazyStart capabiliyt only starts bundles
when they are first "accessed" (ie.., when someone tries to load
a class from them).  Here the bundles register services (by running
code when the bundle starts) that others then discover.  That is,
the services need to be registered before the consumers can discover them.

The simple answer in the case of services
is to look into Declarative Services.  Equinox includes an implementationof
this.

As for starting all prereqs, no, we
do not have any explicit support for this. It would however be reasonably
easy to implement.  See PackageAdmin for some methods that help you
traverse the dependency graph.

Subject	Re: [equinox-dev] Autostarting required plugins

Abhishek,
 
Take a look at:
 
http://www.eclipse.org/equinox/quickstart.html
 
Pay particular attention to the section titled "Configurations
and all that...".
 
You can use the "org.eclipse.core.runtime" and
"org.eclipse.update.configurator" bundles along with the "Eclipse-AutoStart"
manifest header to automatically install and start your bundles. 
 
See more on Eclipse-specific bundle manifest headers at
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/misc/bundle_manifest.html
 or look at the help contents of your Eclipse
install.

How do I autostart the plugins on which my plugin depends.
Here is the
scenario.

Plugin C requires plugin A and plugin B. 

Plugin C uses services registered by both the plugins. But when I try to
use the services in plugin C, I get an error. This is because plugin A
and B have not been started. I tried doing it this way and it worked. 

osgi.bundleclipse.product=A.pro
es=A,B@2:start,C@2:start,org.eclipse.core.runtime@2:start
osgi.bundles.defaultStartLevel=4

But I am looking for a method which would autostart all my dependencies
when I start the plugin C. Any ideas how can this be done? 

Thanks
Abhishek
