Development of REST's web service that connects XML databases (JAVA)

Please lend me your wisdom!I tried to do it on my own for about a week while looking at books and the Internet, but it was perfect, so let me ask you a question here.

It's my first time doing programming.
You must create a REST web service that retrieves information from the XML database in xml and returns it in XQuery.

Contents:
XML database (attached image>10 items are listed in XML for each plane, including the name of the plane, date of manufacture, image, and description)
I want to write a REST web service in Java to view this data.

XML database

The goal is
on the server. Example: I want to sort the date of manufacture in order of new
　　→ See data from this database at that time
　　→ Data such as sorted photos are displayed

Software we have arranged for this development:
Tomcat 8.0 localhost
Jersey 2.0
Eclipse 4.4 (package with Luna PHP, etc.)
JAVA 1.8
JDK8

Books and
for a complete beginner. Tutorial on YouTube and Webseite (http://www.vogella.com/tutorials/REST/article.html, http://javabrains.koushik.org/tutorials/javaee_jaxrs/Introduction.html, installationInstall and launch each software individually for

The flow is
on Eclipse. Write Web service programming
Create a page with @path, etc. and corresponding java page as follows

Create Web Client Pages

Or, in this case, is it okay to just use the web client side?
Please let me know if there are any good methods or sites (regardless of language) that have programs to refer to.
Thank you for your cooperation.
