Hi All,

I wish to "initialize" certain non-static classes at the beginning of a
plugin startup. I want to access this class using some kind of
mechanism. Presently I am using a workaround by declaring them in a view
and obtaining the instance of the view using

Viewpart view =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().
findViewReference(View.ID).getView(false);

view.getObject();

I looked at the startup extension point but I am not sure if it could
get the job done. Any help would be great.

Thank,
Prasad

Often you see the plugin activator class (subclass of AbstractPlugin or
AbstractUIPlugin) have references to objects that are used across the
plugin. So in the activator's start() method you initialize them and
then provide access to other classes via getter methods.

Or you could use a factory that provides access to the shared objects
and call its initialization method(s) from the activator's start() method.

Hope this helps,
Eric

I have tried this but as i said I am not able to obtain non-static objects.

MyPlugin.<non-static object> is not possible by this method.

Can you please elaborate as to how I can achieve this.I am just not able
to obtain the non-static instance of the object I want.

If you let the Eclipse proejct wizard generate the activator class for
you, you'll notice that it includes a static singleton variable and
accessor method (getDefault()). You can use this to get to the instance
and through that get to any references to other objects that it contains.

Hope this helps,
Eric

Works fine now. Thanks a lot.
