MacOS X

MacOS has a number of command line package managers for open source components. We recommend using SDKMAN! to manage Java and Tomcat environment.

Java

Make sure you have a Java Runtime Environment (JRE) installed on your system. GeoWebCache requires a Java 17 environment, and is also tested with Java 21.

  • Required: Java Development Kit 17 (JDK 17)

    Open JDK:

    https://adoptium.net/temurin/releases/?version=17 Temurin 17 (LTS) - Recommended

  • SDKMan!

    # list to determine latest Temurin JDK 17
sdk list java 17

# Installing latest Temurin JDK 17 shown above
sdk install java 17.0.15-tem

# Select Java for use
sdk use java 17<tab>

See Upgrading for compatibility table.

Apache Tomcat

GeoWebCache requires a container supporting the Jakarta EE Servlet 6.1 specification. Apache Tomcat 11 and Jetty 12 are tested; other compliant containers should work but are untested.

  1. Navigate to Tomcat 11 Downloads section, and save the zip file listed under Binary Distributions / Core.

  • SDKMan!

    # list to determine latest Apache Tomcat 11
sdk list tomcat 11

# Installing latest Tomcat 11 shown above
sdk install tomcat 11.0.6

# Select tomcat for use
sdk use tomcat 11.0.6
