Here my simple code to create Rest api
package com.java.restfulwebservice;
#RestController
public class HelloworldController {

Please import the RestController like below :
import org.springframework.web.bind.annotation.RestController;

Storing base java project inside child project jar (maven, docker)

Thanks for having a look at this!
Max
In the future I'm going to building lots of microservices that are all based upon the same parent java project. These microservices are all going to be using spring cloud and docker.
I currently have the base java project and a child project. The main for each microservices should be inherited from the parent project.
Up till now I've been using
mvn clean package assembly:single
for building the jar for the microservice so that the parent is store inside the jar. Then to run
java -cp MicroService.jar path.to.parent.Main
Which is working fine. I'm sure it's not the best way to go about it and I'd love any advice about improvements.
My problem now is that I want to use docker:build
mvn clean package docker:build
After packaging the microservice using docker:build, how do I specify a path to the parent project's Main since the parent project is no longer being stored in the jar made from docker:build.
Microservice (child)

Error
java.lang.NoClassDefFoundError: org/apache/log4j/Logger

You need to add dependency on log4j
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
to your pom.xml file (after dependency on junit).
You can read about this dependency in maven repo:
http://mvnrepository.com/artifact/log4j/log4j/1.2.17

Can't get Libraries Maven Dependencies to show up

I switched from Juno Eclipse to Kepler and imported my Maven project. However "Maven Dependencies" doesn't show up under Project-Properties-Java Build Path-Libraries and thus i can't compile my project. In Maven Repositories view i can see all my dependencies jar files under Local Repositories. I can manually add External Jar Files but there must be a right way to load them dynamically. I can run "maven install" successfully from Eclipse. I've tried all suggestions from this forum such as - run Maven-Update Project, unchecked Maven-Resolve dependencies from Workspace projects, Window-Preferences-check "Download repository index updates on startup" and "Update Maven projects on startup". Something is weird about Kepler Eclipse. What am i missing?

UPDATE: i solved this problem by copy and paste .classpath and .project files from another Maven project in Eclipse (Kepler) that was created with no issues. I made minor adjustments to these 2 files. I compared pom.xml files and found no discrepancies that would prevent Eclipse from creating my Maven project. It's not an ideal solution but it works for now, no time to solving Eclipse "mysteries". Thanks for the below comments, they pointed me into a right direction and helped to understand a problem better.

How to map my ejbs in order to be able to test them in my Arquillian project?

You have a couple of options.
If your EJB and other JAR are deployed separately to your app, you can use multiple deployments in your test case. Only one is "testable" but both can be deployed. You can simplify the reading of this external JAR file using ShrinkWrap's maven resolver.
If they are wrapped in to a WAR or EAR, just use that WAR or EAR as your deployment.
