Chapter 1. New Features and Enhancements

The JBoss EAP XP manager has been enhanced in JBoss EAP XP 2.0.0.

Improved status command

The status command now provides information about the following:

The command also provides the upgrade prompt if you have an old JBoss EAP XP server installed.

New patch-apply command

JBoss EAP XP manager 2.0 provides a patch-apply command. The command is similar to the patch apply management CLI command, but takes fewer arguments than the management CLI command.

You can use the patch-apply command to apply patches to any patch stream that is enabled on the server. Therefore, you can apply both the base server patches as well as the JBoss EAP XP patches to a server that has JBoss EAP XP patch stream enabled.

New upgrade command

JBoss EAP XP manager 2.0 provides an upgrade command.

Use this command to upgrade your JBoss EAP XP 1.0.x to JBoss EAP XP 2.0.0.

Support for readiness probes in MicroProfile Health

JBoss EAP XP 2.0.0 supports the following readiness probes to determine server health and readiness:

For more information about the readiness probes, see Readiness probes that determine server health and readiness in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

You can now package your application as a bootable JAR or as a hollow bootable JAR in JBoss EAP XP 2.0.0.

Ability to package applications as a bootable JAR

A bootable JAR contains a server, a packaged application, and the runtime required to launch the server.

You can build and package a microservices application as a bootable JAR with the JBoss EAP Maven plug-in. You can then run the application on a JBoss EAP bare-metal platform or a JBoss EAP for OpenShift platform.

The bootable JAR Maven plug-in uses Galleon trimming capability to reduce the size and memory footprint of the server. Thus, you can configure the server according to your requirements, including only the Galleon layers that provide the capabilities that you need.

For more information about packaging your application as a bootable JAR, see The bootable JAR in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

Ability to package applications as a hollow bootable JAR

You can provision a hollow bootable JAR. This JAR contains only the server, so that the server can be reused to run a different application.

For more information about packaging your application as a hollow bootable JAR, see Using a bootable JAR on a JBoss EAP bare-metal platform in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

Secure your application with Red Hat Single Sign-On

You can use the Galleon keycloak-client-oidc layer to install a version of a server that is provisioned with Red Hat Single Sign-On OpenID Connect client adapters.

The keycloak-client-oidc layer provides Red Hat Single Sign-On OpenID Connect client adapters to your Maven project. This layer is included with the keycloak-adapter-galleon-pack Red Hat Single Sign-On feature pack.

You can add the keycloak-adapter-galleon-pack feature pack to your Maven project by specifying the org.jboss.sso:keycloak-adapter-galleon-pack:9.0.10.redhat-00001 feature pack in your project.

For more information about using the keycloak-client-oidc layer, see Securing your JBoss EAP bootable JAR application with Red Hat Single Sign-On in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

For information about configuring the Red Hat Single Sign-On adapter subsystem, see JBoss EAP Adapter in the Securing Applications and Services Guide.

The Maven feature-pack location

In JBoss EAP XP 2.0.0, the JBoss EAP feature-pack location is org.jboss.eap:wildfly-galleon-pack:2.0.0.GA-redhat-00002. You must reference this feature-pack location in the <plugin> element in the pom.xml file of your Maven project.

For more information about the JBoss EAP JAR Maven plug-in supported in JBoss EAP XP 2.0.0, see JBoss EAP Maven plug-in in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

Content trimming added to JBoss EAP XP

The content trimming capability introduced to support JBoss EAP on OpenShift is now supported when using JBoss EAP XP. For more information, see Capability trimming in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

New Galleon layers

Several new Galleon layers have been added, including a layer that supports Eclipse MicroProfile capabilities. For more information see Decorator layers in Using Eclipse MicroProfile with JBoss EAP XP 2.0.0.

OpenShift quickstarts

Quickstarts released in JBoss EAP XP 1.0.0 to support OpenShift were Tech Preview.

As of JBoss EAP XP 2.0.0, these quickstarts are fully supported.

Eclipse MicroProfile quickstarts for the bootable JAR

JBoss EAP XP 2.0.0 provides Eclipse MicroProfile quickstarts that you can use to understand the bootable JAR feature.

Each quickstart provides a small, specific, working bootable JAR example. Use the quickstarts to run and test bootable JAR examples on your chosen platform.

Use the following Eclipse MicroProfile quickstarts to test the bootable JAR on either a bare-metal platform or an OpenShift platform:

CodeReady support for bootable JAR

You can now use CodeReady Studio and CodeReady Workspaces to create a bootable JAR for baremetal platforms.

Support for building a bootable JAR for OpenShift in CodeReady Studio is pending the release of CodeReady Studio 12.18.0.

Support for building a bootable JAR for OpenShift in CodeReady Workspaces is pending the release of CodeReady Workspaces 2.6.0.

These releases add support for devfiles, which are required to build a bootable JAR for OpenShift.
