Appendix B: Rebuild Rules

## B Packaging the Test Applications in Servlet-Compliant WAR Files With VI-Specific Information

If you are using a compatible implementation, other than Eclipse Jersey 4.0, please consult documentation which may contain additional details specific for that implementation.

The Jakarta REST 4.0 specification specifies how Jakarta REST applications are to be published in a Java SE environment, Jakarta REST endpoint, or Servlet–compliant Web container.

The Jakarta REST TCK comes with prebuilt test WAR files for deployment on Jakarta EE 11 CI, Eclipse GlassFish 6.1, which provides a Servlet–compliant Web container. The WAR files are Eclipse Jersey 4.0-specific, with Eclipse Jersey 4.0’s servlet class and Eclipse Jersey 4.0’s servlet defined in the `web.xml` deployment descriptor. To run the TCK tests against the VI in a Servlet–compliant Web container, the tests need to be repackaged to include the VI-specific servlet, and the VI-specific servlet must be defined in the deployment descriptor.

The Jakarta REST TCK makes it easier for the vendor by including template WAR files that contain all of the necessary files except for the VI-specific servlet adaptor class. The Jakarta REST TCK provides a tool to help with the repackaging task.

This appendix contains the following sections:

- Overview

- Creating the VI-Specific Servlet–Compliant WAR Files

### B.1 Overview

The classes that ship with the Jakarta REST TCK were built using the Eclipse GlassFish 6.1, Compatible Implementation. The archives for tests are built and deployed in the runtime.

### B.2 Creating the TCK VI-Specific Servlet–Compliant WAR Files

All resource and application class files are already compiled. All tests also come with a `web.xml.template` file that is used for generating deployment descriptor files.

Each test that has a Jakarta REST resource class to publish, comes with a template deployment descriptor file. For example, the file `ee/jakarta/tck/ws/rs/ee/rs/get/web.xml.template` contains the following elements:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="5.0" xmlns="https://jakarta.ee/xml/ns/jakartaee" \
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" \
    xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee \
    https://jakarta.ee/xml/ns/jakartaee/web-app_5_0.xsd">
        <servlet>
            <servlet-name>CTSJAX-RSGET</servlet-name>
            <servlet-class>servlet_adaptor</servlet-class>
            <init-param>
                <param-name>jakarta.ws.rs.core.Application</param-name>
                <param-value>ee.jakarta.tck.ws.rs.ee.rs.get.TSAppConfig</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>CTSJAX-RSGET</servlet-name>
            <url-pattern>/*</url-pattern>
        </servlet-mapping>
        <session-config>
            <session-timeout>30</session-timeout>
        </session-config>
    </web-app>

In this example, the `<servlet-class>` element has a value of `servlet_adaptor`, which is a placeholder for the implementation-specific Servlet class. A Eclipse Jersey 4.0-specific deployment descriptor also comes with the Jakarta REST TCK, and has the values for the `org.glassfish.jersey.servlet.ServletContainer`:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="5.0" xmlns="https://jakarta.ee/xml/ns/jakartaee" \
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" \
    xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee \
    https://jakarta.ee/xml/ns/jakartaee/web-app_5_0.xsd">
        <servlet>
            <servlet-name>CTSJAX-RSGET</servlet-name>
            <servlet-class>
                org/glassfish/jersey/servlet/ServletContainer
            </servlet-class>
            <init-param>
                <param-name>jakarta.ws.rs.core.Application</param-name>
                <param-value>ee.jakarta.tck.ws.rs.ee.rs.get.TSAppConfig</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>CTSJAX-RSGET</servlet-name>
            <url-pattern>/*</url-pattern>
        </servlet-mapping>
        <session-config>
            <session-timeout>30</session-timeout>
            </session-config>
    </web-app>

#### B.2.1 To Create a VI-Specific Deployment Descriptor

1. Set the VI Servlet class property.
   Set the `servlet_adaptor` property as System property. This property will be used to set the value of the `<servlet-class>` element in the deployment descriptor before packaging and deploying the archive.
