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?

Answer 1

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 .
