Re: [rap-dev] Rap 2.3 cannot registerServiceHandler from Actviator 
Hi,
the mailing-list is for development related communication only. Please use the newsgroup [1] for questions, support and information exchange between users and developers of RAP. About your question: You can register your service handlers in your application configuration: 

public class MyApplication implements ApplicationConfiguration {

  public void configure( Application application ) {
    ...
    application.addServiceHandler( serviceHandlerId, serviceHandler );
  }

}

More information about ApplicationConfiguration here [2].

Best,
Ivan

Hi Everyone,

I have a plug-in with an activator where I want to register my service handlers. After moving to RAP 2.3 from RAP 1.4 I'm getting InvalidStateException in RWT.getApplicationContext.

What is the best place to register my Service handlers?

Thanks
