Tomcat 10.1.x on Windows

Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages (JSP), and WebSocket technologies. It is widely used to deploy Java-based web applications. This document provides a detailed, step-by-step process for installing and configuring both single-instance and multi-instance Tomcat setups on a Windows machine for OvalEdge deployment.

Pre-requisites

Before proceeding with the installation, ensure the following requirements are met:

• Windows OS (Windows 10 or later recommended)

• Administrator privileges

• Java 17 installed and configured

• Ensure the JAVA_HOME environment variable is set

• Refer to the Java Installation Guide if Java is not configured

Single Tomcat Installation

• Prepare Directory Structure

  Create a base folder, e.g., C:\ovaledge, to store all required files.

  
• Inside this folder, create subfolders:

  • temp

  • extprop

  • Third_party_jars

  
• Place Required Files

  • Configuration Files: Place oasis.properties and log4j.properties inside the extprop folder (provided by GCS team).

    
  • JAR Files: Place required third-party JARs in the Third_party_jars folder.

    
• Download and Extract Tomcat

  • Download Apache Tomcat (ZIP package).

  • Extract contents under C:\ovaledge.

    
• Deploy WAR File

  • Navigate to the webapps folder inside the Tomcat directory.

  • Place the ovaledge.war file (provided by GCS team).

    
• Install Tomcat as a Windows Service

  • Navigate to the bin folder inside Tomcat and open Command Prompt.

    
  • Run the command:

    Copy

    service.bat install tomcat

    
• Configure Java Options for Tomcat

  • Open Tomcat service properties:

    Copy

    tomcat10w.exe //ES//tomcat

    
  • Go to the Java tab and add:

    Copy

    -DOVALEDGE_SECURITY_TYPE=db
    -Dext.properties.dir=file:C:\ovaledge\extprop\
    -Dlog4j.configuration=file:C:\ovaledge\extprop\log4j.properties
    -DOVALEDGE_ENCRYPT_DECRYPT_KEY=client_input
    --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED
    --add-opens=jdk.zipfs/jdk.nio.zipfs=ALL-UNNAMED
    --add-opens=java.base/java.net=ALL-UNNAMED

  • Confirm with GCS/DevOps team:

    • ext.properties.dir path

    • log4j.configuration path

    • Encryption key value

    • Java heap settings (per VM specification)

• Update oasis.properties

  • Configure:

    • Database connection details

    • Elasticsearch configuration (if applicable)

    • Path to third-party JAR files

      

      

      

• Start Tomcat Service

  • Open Services from Windows Start menu.

  • Locate and start the Tomcat service.

    

    
  • In Properties:

    • Set Startup type → Automatic (Delayed Start)

    • Update Log On credentials as required and click OK.

Multi-Tomcat Installation (UI + Job)

For multi-instance setups, two Tomcats are configured:

• Two Tomcats are configured:

  • tomcatui → User Interface (UI)

  • tomcatjob → Job Processing

• Repeat Initial Setup

  • Follow Single Tomcat Installation steps until WAR deployment.

• Duplicate Tomcat Directory

  • Create two copies of the Tomcat directory.

  • Rename:

    • One to tomcatui

    • One to tomcatjob

    
• Update Ports for tomcatjob

  • Navigate to tomcatjob\conf\server.xml.

  • Modify:

    • Shutdown port → 8005 → 8006

      

      

      
    • HTTP port → 8080 → 8081

      

      
• Install and Configure tomcatui Service

  • Navigate to tomcatui\bin and open Command Prompt:

    

    

    
  • In the Java tab, add:

• Install and Configure tomcatjob Service

  • Navigate to tomcatjob\bin and open Command Prompt:

    

    

    
  • In the Java tab, add:

• Final Configuration and Startup

  • Ensure oasis.properties is properly updated.

  • Start tomcatui and tomcatjob services from Services panel.

    
  • Set Startup type to Automatic (Delayed Start) for both.

    

    

  • Update Log On settings with proper credentials and restart services.
