Setup and Configuration

## 4 Setup and Configuration

Note | The Jakarta EE Specification process provides for any number of compatible implementations. As additional implementations become available, refer to project or product documentation from those vendors for specific TCK setup and operational guidance.

This chapter describes how to set up the Expression Language TCK. Before proceeding with the instructions in this chapter, be sure to install all required software, as described in Chapter 3, "Installation."

After completing the instructions in this chapter, proceed to Chapter 5, "Executing Tests," for instructions on running the Expression Language TCK.

Note | The Expression Language TCK is not depended on any particular build tool to run the tests. It will be convenient and advisable to create a Apache Maven project to setup and run the TCK. This chapter will henceforth use instructions and steps to provide setup with Apache Maven as a build tool.

### 4.1 Configuring Your Environment to Run the TCK Against a Compatible Implementation

After configuring your environment as described in this section, continue with the instructions in Chapter 5, "Executing Tests."

Note | In these instructions, variables in angle brackets need to be expanded for each platform. For example, `<JAVA_HOME>` becomes `$JAVA_HOME` on Solaris/Linux and `%JAVA_HOME%` on Windows. In addition, the forward slashes (`/`) used in all of the examples need to be replaced with backslashes (`\`) for Windows. Finally, be sure to use the appropriate separator for your operating system when specifying multiple path entries (`;` on Windows, `:` on UNIX/Linux). On Windows, you must escape any backslashes with an extra backslash in path separators used in any of the following properties, or use forward slashes as a path separator instead.

1. Set the following environment variables in your shell environment:

   1. `JAVA_HOME` to the directory in which Java SE 21 is installed

   2. `M2_HOME` to the directory in which the Apache Maven build tool is installed.

   3. `PATH` to include the following directories: `JAVA_HOME/bin`, and `M2_HOME/bin`

2. Set the following System properties:

   1. Set the `webServerHost` property to the name of the host on which Jakarta EE 12 CI is running.
      The default setting is `localhost`.

   2. Set the `webServerPort` property to the port number of the host on which Jakarta EE 12 CI is running.
      The default setting is `8080`.

   3. Set the `el.classes` property to the directory of Jakarta EE 12 CI with implementation jar and api jar.

   4. Set the `porting.ts.url.class.1` property to your porting implementation class that is used for obtaining URLs.
      The default setting for this property is `com.sun.ts.lib.implementation.sun.common.SunRIURL`.

3. Set the below jars to the classpath

   1. JAR file for the Expression Language 6.1-SNAPSHOT API.
      eg. `${webServerHost}/modules/jakarta.el-api.jar`.

   2. JUnit 5 jars (5.7.2+) Maven cordinates :

                 <dependency>
                    <groupId>org.junit</groupId>
                    <artifactId>junit-bom</artifactId>
                    <version>5.7.2</version>
                    <type>pom</type>
                    <scope>import</scope>
                 </dependency>

   3. sigtest-maven-plugin (1.4) to run the signature tests. Maven cordinates :

                <dependency>
                      <groupId>jakarta.tck</groupId>
                      <artifactId>sigtest-maven-plugin</artifactId>
                      <version>2.2</version>
                  </dependency>

   4. Apache Tomcat 12 CI jars
      For eg, if you are using the Apache Tomcat 12 CI below jars need to be added to Classpath

          ${webServerHost}/modules/expressly.jar:

4. Provide compatible implementation of the porting package interface provided with the Expression Language TCK.
   The porting package interface, `TSURLInterface.java`, obtains URL strings for web resources in an implementation-specific manner. API documentation for the `TSURLInterface.java` porting package interface is available in the Expression Language TCK documentation bundle.

5. If the Expression Language TCK test applications are published on a Servlet 5.0-compliant Web container to run the CI, the `servlet_adaptor` property needs to be set as System property, and CI-specific WAR files containing the Servlet information need to be created for publishing.
   The CI-specific WAR files should never override any existing files that come with the TCK. Refer to Appendix B, "Packaging the Test Applications in Servlet-Compliant WAR Files With VI-Specific Information," for more information.

### 4.2 Configuring Your Environment to Repackage and Run the TCK Against the Vendor Implementation

Not needed for the EL TCK.

### 4.3 Publishing the Test Applications

Not needed for the EL TCK.
