## 3 Installation

This chapter explains how to install the Expression Language TCK software.

After installing the software according to the instructions in this chapter, proceed to Chapter 4, "Setup and Configuration," for instructions on configuring your test environment.

### 3.1 Obtaining the Reference Implementation

You can obtain the EL Reference Implementation (RI) (RI) software from Java Licensee Engineering (https://javapartner.oracle.com).

### 3.2 Installing the Software

Before you can run the EL TCK tests, you must install and set up the following software components:

- Java EE 8 RI

- Java SE 8

- EL 3.0 RI, which is RI

- EL TCK version 3.0, which includes:

  - JDOM 1.0

  - Apache Commons HTTP Client 3.1

  - Apache Commons Logging 1.1.1

  - Apache Commons Codec 1.3

  - Apache Ant 1.8.4

- The EL 3.0 Vendor Implementation (VI)

Follow these steps:

1. Install the Java SE 8 software, if it is not already installed.
   Download and install the Java SE 8 software from http://www.oracle.com/technetwork/java/javase/downloads/index.html. Refer to the installation instructions that accompany the software for additional information.

2. Install the EL TCK 3.0 software.

   1. Copy or download the EL TCK software to your local system.
      You can obtain the EL TCK software from the Java Licensee Engineering (https://javapartner.oracle.com) Web site. The EL TCK software is located in the Web site’s Download Center area.

   2. Use the `unzip` command to extract the bundle in the directory of your choice:
      `unzip eltck-3.0_dd-Mmm-YYYY.zip`
      This creates the TCK directory. The TCK is the test suite home, `<TS_HOME>`.

   The Reference Implementation is used to validate your initial configuration and setup of the EL TCK 3.0 tests, which are explained further in Chapter 4, "Setup and Configuration."
