[KB7088] Install the ESET PROTECT Web Console using JDK (Windows)

I am a Linux user

See the related articles on installing Java on:

• SUSE Linux Enterprise Server 15
• Debian 10
• CentOS 7  

1. Download the Windows .msi installation file for Amazon Corretto 17 or for Amazon Corretto 21.

2. Double-click the .msi file to start the Installation Wizard.

3. Follow the steps in the wizard.

   You have the option of setting a custom installation path. By default, Amazon Corretto 17 is installed at C:\Program Files\Amazon Corretto\. If you set a custom path, make a note of it for the next step.

4. When the Installation Wizard is finished, set the JAVA_HOME and PATH environment variables.

   Set JAVA_HOME to the installation location, noting that the directory contains the currently installed version. See the following examples for versions 17 and 21.

• Version 17: Set JAVA_HOME as C:\Program Files\Amazon Corretto\jdk17.0.10_7. Add %JAVA_HOME%\bin to the current PATH variable.
• Version 21: Set JAVA_HOME as C:\Program Files\Amazon Corretto\jdk21.0.2_13. Add %JAVA_HOME%\bin to the current PATH variable.

5. Verify the installation by running java -version in a command prompt. You should see the following output.

   Version 17
   openjdk version "17.0.10" 2024-01-16 LTS
   OpenJDK Runtime Environment Corretto-17.0.10.7.1 (build 17.0.10+7-LTS)
   OpenJDK 64-Bit Server VM Corretto-17.0.10.7.1 (build 17.0.10+7-LTS, mixed mode, sharing)
   
   Version 21
   openjdk version "21.0.2" 2024-01-16 LTS
   OpenJDK Runtime Environment Corretto-21.0.2.13.1 (build 21.0.2+13-LTS)
   OpenJDK 64-Bit Server VM Corretto-21.0.2.13.1 (build 21.0.2+13-LTS, mixed mode, sharing)

This migration scenario does not require the reinstall of Apache Tomcat.

1. Navigate to the Apache Tomcat location (for example, C:\Program Files\Apache Software Foundation\Tomcat 7.0\bin\Tomcat7w.exe)

2. In the Apache Tomcat 7 Properties window, click the General tab and click the Stop button to stop the Apache Tomcat service.

3. Uninstall your current JDK.

4. Install your desired JDK.

5. Go back to the Apache Tomcat Properties window and click the Java tab.

6. Under the Java Virtual Machine path, select the correct path to the jvm.dll file based on the JDK. (for example, for Amazon Corretto, C:\Program Files\Amazon Corretto\jdk11.0.7\bin\jvm.dll)

7. Go back to the General tab, and click Start to start the Apache Tomcat service.

8. Verify that you can log in to your Web Console.

This migration scenario requires the reinstall of Apache Tomcat.

1. Back up the necessary files:
   C:\Program Files\Apache Software Foundation\Tomcat 7.0\.keystore
C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\Server.xml
C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\Tomcat-users.xml
C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\Serverinfo.properties
C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\era\WEB-INF\classes\sk\eset\era\g2webconsole\server\modules\config\EraWebServerConfig.properties

2. Download and run the JDK installer.

3. To change which JDK is used by Apache Tomcat, you must reinstall Apache Tomcat.

4. If you are running more than Web Console on your instance of Apache Tomcat, we recommend that you check the official Apache Tomcat upgrade/migration documentation.

5. If you use a custom SSL certificate stored in the Tomcat folder, back up the certificate.

6. Uninstall the current version of Apache Tomcat.

7. Delete the following folder if it is still present in your system:

   C:\Program Files\Apache Software Foundation\Tomcat 7.

8. Run the Apache Tomcat installer from the ESET PROTECT All In One installers folder. During the installation, select the path to your JDK you intend to use instead of the Java SE. (for example, C:\Program Files\Amazon Corretto\jre8).

9. When you are finished, deselect the check box next to Run Apache Tomcat.

10. Verify that the Apache Tomcat Service is not running.

11. Copy the era.war file from the installers folder to the Apache Tomcat web applications folder: click Start → Apache Tomcat → Tomcat Program Directory and open the webapps folder (on most Windows operating systems – C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps)

12. Allow a few minutes for the file extraction and Web Console installation. The installation will run silently, but you can verify a successful installation by the presence of the era folder inside the webapps folder.

13. If you run the Web Console (Apache Tomcat) on a different computer than the Server component, restore the backed-up EraWebServerConfig.properties file to its original location.

14. Verify that the Apache Tomcat is using the JDK you selected. To do so, click Start → All Programs → Apache Tomcat → Monitor Tomcat. In the Java tab under Java Virtual Machine, there should be the path to the JDK you selected.

15. You can now start the Apache Tomcat service and verify that the Web Console is running without issues.
