Answer 1

java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;

The Application#getProperties() method was introduced in JAX-RS 2.0. And this error typically happens when you mix JAX-RS 1.x and JAX-RS 2.x.

So check the JARs on your classpath and remove everything that relates to JAX-RS 1.x (and Jersey 1.x).

Once you are using Maven, you can run mvn dependency:tree and check what's going on with your dependencies.

I also see a few things that may cause some headaches:

1. See below the correct Servlet API dependency for Tomcat 8 (don't forget the provided scope):

   
       javax.servlet
       javax.servlet-api
       3.1
       provided
   
   

2. Ensure that all Jersey dependencies use the same version.

3. You probably don't need the javax.ws.rs-api, jersey-server and jersey-common dependencies.

   • Use jersey-container-servlet, jersey-media-json-jackson and jersey-media-multipart dependencies.

   • The jersey-container-servlet dependency uses javax.ws.rs-api, jersey-server and jersey-common as transitive dependencies.

4. You probably don't need jar in your dependencies.
