Corticon requires a supported Java distribution to run.
Corticon Studio
The Corticon workbench bundles a Java distribution for use in running Studio. This Java distribution should not be used to run Corticon Server, Web Console or otherwise be used in a production or server environment.
Note: Cannot install Studio into an existing
Eclipse— Corticon Studio ships with Java 11 or higher, which introduces changes
in how JAR files are handled: Java no longer supports the direct addition of custom JARs
to the classpath as earlier versions did. As a result, the ability to drop extension
JARs into the Eclipse plugin folder is no longer functional. The recommended method for
adding extension JARs is in an installed Corticon Studio either:
- For Eclipse tools, choose Help > Install New Software, and then
typically choosing tools at
https://marketplace.eclipse.org/. - For your extensions, such as extended operators and service callouts, in a Rule Project, choose Properties > Corticon Extensions.
Corticon Server and Utilities
The runtime components require the user to provide a supported Java distribution, as listed in Corticon 7.3 Supported Platforms. The user is responsible for ensuring that this Java distribution has any required security updates.
Note: You can verify the Java on the path by opening
a command prompt window, and then entering
java -version. If you get
Java 21 as the response, you are all set. Otherwise, you need to revise system variables
and perhaps even the environment variables.Java distributions are available from multiple sources. One good source is Adoptium: https://adoptium.net/
Note: Corticon installers utilize an embedded Java distribution for
the purpose of performing install and uninstall operations. This Java distribution
should not be used for any other purpose.
