ORDS "java -jar ords.war" command error

Question

I'm following this guide: https://docs.oracle.com/cd/E56351_01/doc.30/e87809/getting-started-with-RESTful-services.htm#AELIG90200

but I got stuck in "F.2 Create a RESTful Service from a SQL Query".

In the folder where Oracle REST Data Services was installed, I entered the following command in a command prompt:

java -jar ords.war user test_developer "SQL Developer"

and I got this error:

Why is this for? and How to fix it?

Issue the JAXB issue below, which we have addressed for the next release. — Kris Rice, Feb 04 '18 at 15:07

An issue with Java 9 and addressed in this SO post

Your issue can be worked around by issuing this

java -jar --add-modules java.xml.bind ords.war user test_developer "SQL Developer"

Also, if you're wanting to build RESTful Services with ORDS, you can also use SQL Developer and simply connect to the REST enabled schema and use the REST feature in the connection tree. I talk about this here.

`--add-modules java.xml.bind` is a temporary solution. Better to move to the standalone download of JAXB. For more on this see JEP 320. – Alan Bateman Feb 02 '18 at 18:00
@AlanBateman +1 We'll have next release of ORDS ready to go out of the box for Java 9/10 – thatjeffsmith Feb 02 '18 at 18:18
Thank you, it worked like a charm. I will follow your guide from now on. – Sebastián Feb 02 '18 at 18:25
