rcp application with multiple plugins [message #506176]

Hi,
I work on rcp application. I have the main plugin, including application and product definitions. I want to add java library and another plugin, that is based on this library implementing additions to the main plugin. What is the appropriate plugin architecture? Should I create java library as a separate plugin also? How to define the another plugin - as feature plugin or as fragment plugin, etc ? Any explanations and examples will be appreciated. Thanks

to add another java library, you do have to put it in a plugin
somewhere. You can then require it (or import its packages) and use it
directly from another plugin.

If you have a main plugin and you want another plugin to contribute
extensions to it, the common eclipse pattern is to use Extension
points/Extensions.

ex: org.eclipse.ui defines org.eclipse.ui.views EP and the IViewPart
class. when it starts up, it reads all Extensions and (based on some
logic) instantiates the contributed implementations of IViewPart through
Extension/IConfigurationElement

org.eclipse.ui.views.log requires org.eclipse.ui, contributes a view to
org.eclipse.ui.views, and implements IViewPart in its contribution.

I have an additional question:
I want an another plugin to contribute additional editor to the rcp application. If some group of customers don't want this extension - they need to remove it in plugin.xml of the main plugin? Are there other way to regulate what plugins to take for rcp? Thanks

Hi stella,

in matter of fact who keeps information about the contribution is the
extension not the plugin...
if a user dont want an extension just dont have to install it.
to remove a extension-plugin is the same process using the update manager or
enable/disable plugin or remove it phisically.

if im not wrong the concept behind is CBM (component bussiness modelling)
and SAAS, based all in OSGI.
