How to access the endpoint assembled inside an ear file? - rest

Question

I am building a web app using java ee as backend and angular as frontend. As application server i have chosen Wildfly 13. As a build tool for backend I have chosen Maven. I have created this structure for the project :
-Project
---Project-ear
---Project-model
---Project-service
---Project-service-api
Neither of this modules packages a war file, I package 3 jars and in the end I assemble them in an ear file using
"Project-ear"
I have tried to consume the exposed service inside
"Project-service"
but I cant. It seems I don't set the right url. Can somebody help me please?
I have tried to access the following urls:
http://localhost:8080/Project-ear/Project-service/resources/test/testDtos/,
http://localhost:8080/resources/test/testDtos/
I have created the RestActivator class :
#ApplicationPath("/resources")
public class RestActivator extends Application {
}
And I have created a Resource class :
#Path("/test")
public class TestResource {
#GET
#Path("/testDtos")
#Produces(MediaType.APPLICATION_JSON)
public Response getWorkflowDiagram() {
TestDto testDto = new TestDto();
testDto.setFirstName("Test");
testDto.setLastName("Test");
return Response.ok(testDto).build();
}
}
I don't get any error message, I just can't access the URL endpoint.

When you configure the Application Server (Wildfly) and add the ear artifact, it creates a target folder in your ear-folder. There you can find a file called application.xml. You have to set the context-root like that:
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/application_7.xsd"
version="7">
<module>
<web>
<web-uri>test.war</web-uri>
<context-root>/api</context-root>
</web>
</module>
</application>
Your URL depends on what you have set in context-root in application.xml and how have set the application path in your root class (RestActivator).
In this example:
localhost:8080/api/resources
And to get access to your method in TestResource:
localhost:8080/api/resources/test/testDtos
