gwt rpc - how to minimize servlet declarations for gwt-rpc in web.xml? -


sorry still beginner in gwt. have noticed when project grow , declarations of servlets rpc in web.xml file many, many , many. single *serviceimpl class , need define in web.xml as

<servlet>     <servlet-name>greetservlet</servlet-name>     <servlet-class>com.my.testing.server.greetingserviceimpl</servlet-class> </servlet>  <servlet-mapping>     <servlet-name>greetservlet</servlet-name>     <url-pattern>/testing/greet</url-pattern> </servlet-mapping>

if if have 30 *serviceimpl class, may take 200 lines in web.xml rpc calls. , know

  1. is web.xml file place declare rpc servlets ?
  2. has someways skip declarative styles (i mean via annotations '@' etc) ?

gwt works pretty without these declarations in web.xml, using annotations:

/*  * server-side rpc-implementation  */ @webservlet(name = "yourservice", urlpatterns = {"/path/to/yourservice"}) public class yourserviceimpl extends remoteserviceservlet implements yourservice {    public void dosomething() {     //some code   } }  /*  * corresponding rpc-interface  */ @remoteservicerelativepath("path/to/yourservice") public interface yourservice implements remoteservice {    void dosomething(); }

the resulting path servlet depends on project structure. if project deployed in servers root, find servlet there (with path specified urlpatterns above). however, if deployed project under own uri, have prepend urlpattern.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
