thx but as i mentioned in previous post, i already got a "MainModule"
called ServerModule. My Problem is how to use it on Serverside. All
Examples doing the bootstrapping in main - cretaeInjector,
getInstance. But in the guice/gwt/rpc case the injector instance is
created in GuiceServletContextListener. With this i can't get an
injector where i want it. in my special case my servlets need such an
injected class:
public class MyServiceImpl extends RemoteServiceServlet implements
MyService {
@Override
public ArrayList<SomeClass> getList() {
return injector.getInstance(Dataprovider.class).getList();
}
}
But how to get an Injector instance at this place? Should i create an
injector wherever i need one? or save the injector created inside my
GuiceServletContextListener and make it available via a getI()-Method?
