I have declared an empty Application class here:
public class ScenarioPlannerApp extends Application{}
I am using the following simple web service with URL http://localhost:9050/scenarioplanner/api/models/:
The Resource Code is :
@Path("")
public class ModelController
{
@GET
@Path("/models/")
@Produces(MediaType.APPLICATION_JSON)
public Response getModels() throws Exception {
ModelService modelService = null;
List<CarModelData> models;
models = modelService.getModelDetails();
logger.debug("Webservice Name [/models/] execution completed with HTTP status OK [200]");
//return Responsestatus(Status.OK).entity(models).build();
return Response
.status(Status.OK)
.entity(models)
.build();
}
I have read many answers on stack overflow, but not able to solve this error. I have spent the whole day trying to debug this error but in vain!
Any help will be highly valued and appreciated!!
Solution
Fixing the application path
Annotate the class that extends Application with @ApplicationPath:
@ApplicationPath("/api")
public class ScenarioPlannerApp extends Application {
...
}
Fixing the resource path
Annotate the ModelController class with @Path using /models as value. The getModels() method doesn't need a @Path annotation in this situation:
@Path("/models")
public class ModelController {
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getModels() throws Exception {
...
}
}
It's important to remember that a @Path annotation on a resource class designates a resource.
Creating resource methods
It's very likely you'll need to add more methods to the ModelController resource class. See the examples below:
To have a method that handles POST requests on /api/models, you can have the following:
@POST
@Consumes(MediaType.APPLICATION_JSON)
public Response createModel(Model model) throws Exception {
...
}
To have a method that handles GET requests on /api/models/{id}, you can have the following:
@GET
@Path("/{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response getModel(@PathParam("id") Long id) throws Exception {
...
}
And it's important to remember that a @Path annotation on a resource method of a resource class designates a sub resource of a resource.
