Chapter 14. Data Grid Modules for Red Hat JBoss EAP

To use Data Grid inside applications deployed to Red Hat JBoss EAP, you should install Data Grid modules that:

  • Let you deploy applications without packaging Data Grid JAR files in your WAR or EAR file.
  • Allow you to use a Data Grid version that is independent to the one bundled with Red Hat JBoss EAP.
Important

In Red Hat JBoss EAP (EAP) 7.4 applications can directly handle the infinispan subsystem without the need to separately install Data Grid modules. After EAP 7.4 GA is released, Data Grid will no longer provide EAP modules for download.

  1. Log in to the Red Hat customer portal.
  2. Download the ZIP archive for the modules from the Data Grid software downloads.

  3. Extract the ZIP archive and copy the contents of modules to the modules directory of your Red Hat JBoss EAP installation so that you get the resulting structure:
