I wanted to have base uri for my rest application at the time when servlet context get initializing. It is easily available at resource classes with the help of UriInfo. But I need it at the time my app is getting initialize. i am using jersey api (2.13).

Can any body suggest the way to get the base uri.

@ApplicationPath("rest")
public class RestApplication extends ResourceConfig {

public RestApplication() {

// I Need The Base URi Here 
  }
}

Or may be in this method

public void contextInitialized(ServletContextEvent event) {
    // I Need The Base URi Here 

}

What do you mean with *base uri*? – cassiomolin Apr 01 '16 at 12:49
HttpServletRequest is available in resource classes . but i need it in ServletContextListener or ResourceConfig or any where else which is being called at the time of initialisation of application by servlet container. – Krishna Kant Apr 01 '16 at 12:51
@KrrishRoy, please, give some code snippet to show the place you want to get base uri and where base uri should be obtained? – sphinks Apr 01 '16 at 12:53
base uri : - protocol(https/http)://:/context path – Krishna Kant Apr 01 '16 at 12:53

And, for the context path, use [`ServletContext.getContextPath()`](http://docs.oracle.com/javaee/7/api/javax/servlet/ServletContext.html#getContextPath--). – cassiomolin Apr 01 '16 at 12:59
@CássioMazzochiMolin and what about the host ip and port and the protocol ? – Krishna Kant Apr 01 '16 at 13:01
See my comment above... – cassiomolin Apr 01 '16 at 13:02
