Assembling JAX-RS web applications
After you develop the Java class files for your Java API for RESTful Web Services (JAX-RS) web application and edit the web.xml file to enable the JAX-RS servlet, assemble the application.
Identify the assembly tool to use to assemble the application. The web application is assembled into a WAR package. We can assemble the WAR package into an EAR package if required.
Before assembling the web application, ensure that we have customized the web.xml file to enable the JAX-RS servlet or filter configuration.
To learn more, see the information about configuring the web.xml file for the JAX-RS application.
We must add the JAX-RS libraries to the web application in the WEB-INF/lib directory before you assemble the web application.
By packaging your JAX-RS application classes into the WEB-INF/classes directory of your WAR package and editing the web.xml file, you can use the built-in JAX-RS runtime environment.
Procedure
Create the WAR package using assembly tools.
- Package your compiled JAX-RS Java classes into the WEB-INF/classes directory of your WAR package.
- Package the web.xml file for your web application in the WEB-INF/ directory into the WAR package.
Results
A WAR package is created that contains the web application. If needed, you can add the WAR package to an EAR package. The application server can deploy either the WAR or EAR packages.
What to do next
Deploy the web application.
