Using an unsupported version may lead to unexpected results. Before you can begin working with any of the DigipassONE App SDKs, you should ensure that your development environment includes all the required components and that they are correctly configured. - [Java Development Kit](/dpoa/docs/digipassone-authenticate-web-trial-set-up-your-web-development-environment#java-development-kit) - [Eclipse IDE](/dpoa/docs/digipassone-authenticate-web-trial-set-up-your-web-development-environment#eclipse-ide) - [Apache Tomcat](/dpoa/docs/digipassone-authenticate-web-trial-set-up-your-web-development-environment#apache-tomcat) - [Essential Eclipse configurations](/dpoa/docs/digipassone-authenticate-web-trial-set-up-your-web-development-environment#essential-eclipse-configurations) ## Java Development Kit | Component | Supported versions | Source(s) | | --- | --- | --- | | JDK | 17, 21, 25 | - Oracle: [Java SE Platform](https://www.oracle.com/ca-en/java/technologies/downloads/) - Open source: [Adoptium Eclipse Temurin](https://adoptium.net/) | To install a Java Development Kit: 1. Download the Java SE Development Kit from: - the Oracle website, or - an open source alternative, e.g., *Eclipse Temurin*, *OpenJDK*, or *Amazon Corretto*. 2. Install the JDK: - **On Windows:** - Run the installer file and follow the instructions step-by-step. - **On macOS:** - Run the downloaded .dmg or .pkg installer and follow the instructions step-by-step, or - Use *Homebrew*, e.g.: `brew install openjdk@17` 3. Verify which version JAVA_HOME is pointing to: - **On Windows:** - Run `echo %JAVA_HOME%` in the command prompt. - **On macOS:** - Run `echo $JAVA_HOME` in a terminal. - If `JAVA_HOME` is pointing to an older version, update it to point to the version you just installed. 4. Set the Environment Variables: - **On Windows:** 1. Type *Environment Variables* in the Windows search bar. 2. Click **New** under *System Variables*. 3. Add `JAVA_HOME` as the variable name, and the JDK installation path as the value. 4. Locate the `Path` variable, click **Edit**, then click **New**, and adding `%JAVA_HOME%\bin` - **On macOS:** - Find your JDK installation path, e.g., via `/usr/libexec/java_home -V` - Open your shell profile file, e.g., `~/.zshrc` for the default zsh shell, or `~/.bash_profile` if using bash. - Add the following lines: `export JAVA_HOME=$(/usr/libexec/java_home -v 17)` `export PATH=$JAVA_HOME/bin:$PATH` - Apply the changes with `source ~/.zshrc` (or the equivalent for your shell), or open a new terminal window. 5. Confirm that the installation was successful. - **On Windows:** - Using the command prompt, type `java -version`. - **On macOS:** - Using the terminal, type `java -version`. - The installed Java version should then be displayed. ## Eclipse IDE | Component | Supported versions | Source(s) | | --- | --- | --- | | IDE | 2026-06 R | [Eclipse IDE for Enterprise Java and Web Developers](https://www.eclipse.org/downloads/packages/release) | To install Eclipse IDE: 1. Download the supported version of the **Eclipse IDE for Enterprise Java and Web Developers** installer from the Eclipse Foundation website. 2. Run the installer and choose the folder where it will be extracted before clicking **Install**. 3. If required to, choose a workspace directory. ## Apache Tomcat | Component | Supported versions | Source(s) | | --- | --- | --- | | Web server | Apache Tomcat 10.1 | [Apache Tomcat](https://tomcat.apache.org/) | To install Apache Tomcat as your local web server: 1. Go to the Apache Tomcat homepage and select the desired version from the *Download* section. 2. On the Software Download page, scroll down to the **Binary Distributions** section and click on one of the following: - `zip (pgp, sha512)` - `tar.gz (pgp, sha512)` - `Windows zip (pgp, sha512)` 3. Extract the zip to a secure location on your machine. 4. Record the path for future reference. ## Essential Eclipse configurations ### Add Tomcat Runtime to Eclipse 1. On **Eclipse,** access the **Servers** view. - If there is no such tab, click **Window** on the top menu, hover over **Show View** and look for *Servers.* - If it is still not listed, enter `Servers` into the filter, expand the **Server** folder, select **Servers**, and click **Open** (or **OK**). 2. **Create** a new server and specify the Server Type by expanding the Apache folder, selecting *Tomcat v10.1 Server*, and clicking **Next**. 3. Specify the Tomcat installation directory by selecting the path from step 3 of [Apache Tomcat](/dpoa/docs/digipassone-authenticate-web-trial-set-up-your-web-development-environment#apache-tomcat). 4. Next, choose specific JRE version under the *JRE* dropdown before clicking **Next** or **Finish**. ### A note on JavaScript errors Eclipse can be configured to suppress to skip client-side JavaScript validation and prevent errors from being displayed. However, these errors are harmless and will not prevent Java from compiling. Formerly known as Digipass S3 App SDK. Includes SDKs for Android, iOS and web.
