java - Do not save workbench state in a eclipse RCP app -

i devoloping application eclipse rcp. application should alwaysshow perspective when started. application saves workbench state , when restarted shows same perspective had when closed. tried add

public void initialize(iworkbenchconfigurer configurer){     configurer.setsaveandrestore(false); } 

to applicationworkbenchadvisor class, did'nt work. thought of selection right perspective, don't know add such piece of code.

how can application show same perspective on startup?

i found out if want same start perspective, can set default perspective during startup.

public class application implements iapplication {     public object start(iapplicationcontext content){         platformui.getworkbench().getperspectiveregistry().setdefaultperspective("youperspective here");          //other code...     }      //other code... } 

update: works if enable "clear workspace" in run configurations. current solution delete workbench file during program startup.
