Hi Rohit,
if you run within Eclipse / Equinox, you have to be very careful to not
use a second Injector besides the one that is part of the UI plugin.
Please note that the UI plugin - even though it is called UI plugin -
does not necessarily need a UI. The bundle usually works fine in
headless mode. Thus I recommend the use the injector that is provided by
the UI plugins' activator in your batch application.
Regards,
Sebastian

Hi Sebastian,
Thanks for your reply.
Based on your suggestion i changed my injector, to use the Injector of the Activator in the UI Plugin like below
Injector injector = DSLActivator.getInstance().getInjector(DSLActivator.DSLName);
I also noticed that the Activator internally, calls Guice to create the Injector itself in the createInjector method, like below.
Module runtimeModule = getRuntimeModule(language);
Module sharedStateModule = getSharedStateModule();
Module uiModule = getUiModule(language);
Module mergedModule = Modules2.mixin(runtimeModule, sharedStateModule, uiModule);
return Guice.createInjector(mergedModule);
At the point of Guice.createInjector(), i get NoClassDefFoundErr, log below , Any suggestions??

Hi Rohit,
you have to make sure that the bundle with the missing class is
contained in your product. PLease note that a bundle name with *.ui does
not necessarily mean that the bundle is not capable of working headless.

Sebastian
