Restlet path param does not work

Question

Below is my routing

public Restlet createInboundRoot(){
 Router router = new Router(getContext());
router.attach("account/profile",UserProfile.class);

Following is the Resource class UserProfile.java

@post
@path("add")
public void addUser(User user){

@post
@path("modify")
public void modifyUser(User user){

@post
public void test(){//only this is called

I want to invoke one resource class and do couple of identical functions for a resource class. That means, my above resource class handles functions related to the UserProfiles such as add, modify. URL are:
account/profile/add => to add a user
account/profile/modify => to modify a user

anyway, above my implementation doesn't work as only the test() method can be invoked through account/profile/

I tried with Pathparams as well.But it also didnot work. For path params:

router.attach("account/profile/{action}",UserProfile.class);

was added and in the resource class,

@post
@path("{action}")
public void addUser(@pathparam("action") String action, User user){ 

Anyone tell me where is my problem.

Can you post your err log here? – Junkman

Thanks karthi for attention. There is no errors thrown.. Server just returns 403 as response – Eosinophil

Well! It means the resource you are trying to access is exist but the server unable to give a proper response. You can try these things, make sure you directory has all permissions and specify a produce type either json or XML by using @ Produces annotation and give a try with @put or @ get methods. Sometimes post is culprit. – Junkman

Thanks Karthi.. I tried with single method annotated @POST with single ULR to the source and then it worked. I don't see any permission issue. This problem rises when 2 URLs calls this resource. – Eosinophil

Any has any thought please ? – Eosinophil

as a side note, don't use action names in the path of your resources. a resource is more about state, note action. If you want action, use the HTTP verbs. – Alcoran

The way you attach your UserProfile server resource is a bit strange. I think that you mixed the native routing of Restlet and the one from the JAXRS extension.

I made some tests regarding your use case and I was able to have the behavior you expect. I used the version 2.3.5 of Restlet.

Here is what I did:

• Since you want to use JAXRS, you need to create a JaxRsApplication and attach it on the component:

  Component component = new Component();
  component.getServers().add(Protocol.HTTP, 8182);
  
      // JAXRS application
      JaxRsApplication application
         = new JaxRsApplication(component.getContext());
      application.add(new MyApplication());
  
      // Attachment
      component.getDefaultHost().attachDefault(application);
  
      // Start
      component.start();
  

• The application simply list the server resources you want to use but doesn't define routing and paths:

  import javax.ws.rs.core.Application;
  
  public class MyApplication extends Application {
      public Set<Class<?>> getClasses() {
          Set<Class<?>> rrcs = new HashSet<Class<?>>();
          rrcs.add(AccountProfileServerResource.class);
          return rrcs;
      }
  }
  

• The server resource defines handling methods and associated routes:

  import javax.ws.rs.POST;
  import javax.ws.rs.Path;
  
  @Path("account/profile/")
  public class AccountProfileServerResource {
      @POST
      @Path("add")
      public User addUser(User user) {
          System.out.println(">> addUser");
          return user;
      }
  
      @POST
      @Path("modify")
      public User modifyUser(User user) {
          System.out.println(">> modifyUser");
          return user;
      }
  
      @POST
      public void test() {
          System.out.println(">> test");
      }
  }
  

• When I call the different paths, right methods are called:

  • http://localhost:8182/account/profile/modify: the modifyUser method is called
  • http://localhost:8182/account/profile/add: the addUser method is called
  • http://localhost:8182/account/profile/: the test method is called

Hope it helps you, Thierry
