Thanks Justin.
Here is what I was doing wrong. I created the folders src/main/java and
src/test/java under rest/hello_rest. When I created the class files, eclipse
was creating the files under the rest/src/java folder instead of
rest/hello_rest/src/java.
So now I made sure that the HelloResource.java file is located under the
correct folder and there were no errors. (But I could see that the
StringFormat and MediaType objects were not being recognized correctly.)
Also I moved the applicationContext.xml file from the resources folder(as
mentioned in the tutorial) to the src/main/java folder (as you mentioned.).
Also made sure the HelloResourceTest.java file is under the correct folder.
Now when I run mvn install under the root module I get the following
compilation error:
