JAX-RS helloworld on Wildfly 10

[bertrandp]

Hi everyone,

I have an issue with this quickstart:

https://github.com/wildfly/quickstart/tree/10.x/helloworld-rs

I am using jdk1.8.0_66, wildfly-10.0.0.CR4 and maven 3.3.3.

So I can deploy the application without any problem using the command: mvn clean install wildfly:deploy

And I can see that the application is deployed and works at http://localhost:8080/jboss-helloworld-rs

But when I try http://localhost:8080/wildfly-helloworld-rs/rest/json to get the xml content I get: "Not Found". Same for json.

It seems that there is an issue with JAX-RS.

Hi,

I think @Path("/") should be @Path("/rest") in HelloWorld.java file.

Regards.

Luis.

Hi,

Yes indeed I also think the path should be @Path("/rest").

I changed it but I get the same: "Not Found" ...

I think there is a class missing which extends Application.

It should work if you add another file which looks like

package org.jboss.as.quickstarts.rshelloworld;

import javax.ws.rs.ApplicationPath;

import javax.ws.rs.core.Application;

@ApplicationPath("rest")

public class JAXRSConfig extends Application {

    public JAXRSConfig() {

    }

}

Hi,

So I my class now extends Application:

@ApplicationPath("/rest")

public class HelloWorld extends Application {

    @Inject

    HelloService helloService;

    @GET

    @Path("/json")

    @Produces({ "application/json" })

    public String getHelloWorldJSON() {

        return "{\"result\":\"" + helloService.createHelloMessage("World") + "\"}";

    }

    @GET

    @Path("/xml")

    @Produces({ "application/xml" })

    public String getHelloWorldXML() {

        return "<xml><result>" + helloService.createHelloMessage("World") + "</result></xml>";

    }

}

When I go to this url: http://localhost:8080/wildfly-helloworld-rs/rest/json I have this error:

16:53:20,919 ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-7) RESTEASY002010: Failed to execute: javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: http://localhost:8080/wildfly-helloworld-rs/rest/json

I am not absolutely sure what you did here.

But as mentioned before you should not change anything in the source file but add an add'l java class that extends Application

[bertrandp]

Indeed it works fine ! Thank you very much.

So in wildfly 10 if I want to deploy a JAX-RS webservice I need to add this class ? And this class only extends Application and specify the ApplicationPath right ?

[mayerw01]

I don't think this is related to WildFly 10 but documented in the API ApplicationPath (Java EE 6 )

"ApplicationPath Identifies the application path that serves as the base URI for all resource URIs provided by Path. May only be applied to a subclass of Application"

[dean.w.schulze]

I get the same error with WildFly 11, and I have an subclass of javax.ws.rs.core.Application.  Deploying the .war (which only contains my Application .class and resource .class files - no web.xml) gives:

Cannot upload deployment: {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.pdfupload.POST_MODULE" => "WFLYSRV0153: Failed to process phase POST_MODULE of deployment \"pdfupload\" Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYRS0006: Could not load JAX-RS Application class Caused by: java.lang.ClassNotFoundException: pdf.upload.server.PdfUploadApplication from [Module \"deployment.pdfupload\" from Service Module Loader]"}}

What do I have to do got get this deployed?
