Chapter 2. Before You Begin

2.1. The difference between Red Hat JBoss Web Server and JWS for OpenShift

The differences between the JWS for OpenShift images and the regular release of JWS are:

  • The location of JWS_HOME/tomcat<version>/ inside a JWS for OpenShift image is: /opt/webserver/.
  • The JWS for OpenShift images do not contain Apache HTTP Server. All load balancing is handled by the OpenShift router, not Apache HTTP Server mod_cluster or mod_jk connectors.

Documentation for JWS functionality not specific to JWS for OpenShift images is found in the Red Hat JBoss Web Server documentation.

2.2. Version compatibility and support

See the xPaaS table on the OpenShift Container Platform Tested Integrations page for details about OpenShift image version compatibility.

Important

The 5.2 version of JWS for OpenShift images and application templates should be used for deploying new applications.

The 5.1 version of JWS for OpenShift images and application templates are deprecated and no longer receives updates.

2.3. Health checks for Red Hat container images

All container images available for OpenShift have a health rating associated with it. You can find the health rating for Red Hat JBoss Web Server by navigating to the catalog of container images, searching for JBoss Web Server and selecting the 5.2 version.
