Could you please start with question? – rudolf_franek
try to extend javax.ws.rs.core.Application instead of declaring a lot of stuff in web.xml . To make it work just extend that class and provide @ApplicationPath("/") annotation on the class that extends it, don't know if it make any change (probably not) but add @Path("/myresource") as a root path to your class. And try to call your service just from browser, URL is gonna be smth like http://localhost:8080/my-app/myresource – ikos23
Kindly explain whats going on apart from displaying the codes. It will make it easier to analyse your problem exactly. – Srishti Sinha

I had the same root cause: java.lang.IllegalStateException: InjectionManagerFactory not found.

After some changes in pom.xml finally it worked. Try as following:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.26-b06</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26-b06</version>
</dependency>

Same problem was here:

Jersey stopped working with InjectionManagerFactory not found

Solution: Downgrade to jersey version "2.26-b03".
