i have a bunch of plugins have that hold some business logic cache. is it possible from some plugin to tell all other plugins to refresh?

if not, then i have to put the cache in a central place.

For inter-plugin communication, you should look at creating OSGi services. You create a service interface and an implementation. All the concerned plugins can look up that service and register. Then the service can inform them of the refresh requirement.

If the business logic cache contains the same info, you can do the same thing. Create a business logic cache service, and have all of the plugins look up that service and talk to it.

Some links on OSGi services:
