Jersey app deployment error - rest

Question

I have a simple jersey based REST Web service where i'm trying to do a test GET run..
Using Jersey 2.7 & Servlet 3.0 container, I have tried configuring the application using the jersey doc ( JAX-RS application without an Application subclass
I have defined a resource
#Path("/bolt")
public class SpringRequestResource extends BaseResource {
#GET
#Produces("text/plain")
public String getHello() {
return "Hello World!";
}
And my deployment descriptor web.xml as
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Alpha</display-name>
<servlet>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/myService/*</url-pattern>
</servlet-mapping>
</web-app>
However, upon throwing a GET request via browser through a url http://myName.xyz.com:6080/[projectName]/myService/bolt
It throws the following exception -
javax.servlet.ServletException: Servlet.init() for servlet javax.ws.rs.core.Application threw exception

Can't seem to figure out the problem here.

Answer 1

I cannot reproduce the issue with Jersey 2.9. You can try to migrate to Jersey 2.9. If it does not help you can create an new issue in https://java.net/jira/browse/JERSEY as this is probably a bug and not your fault. It would be good if you could attach a simple reproducible test case (simple executable maven project that reproduces the problem).
The workaround would be to use extension of Application class or ResourceConfig to configure the application.
