OpenLiberty Java EE 8 Config

22 January 2018

I am working of the latest Development Builds of Open Liberty supporting Java EE 8. You can download them here under "Development builds".

When you create a new server in Websphere/Open Liberty via ${WLP_HOME}/bin/server create server1, the generated server.xml is not configured properly for SSL, Java EE, etc. Here is a minimal server.xml that works:

<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>javaee-8.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>

    <keyStore id="defaultKeyStore" password="yourpassword"/>

    <!-- Automatically expand WAR files and EAR files -->
    <applicationManager autoExpand="true"/>

    <quickStartSecurity userName="admin" userPassword="admin12!"/>

    <!-- hot-deploy for dropins -->
    <applicationMonitor updateTrigger="polled" pollingRate="500ms"
                    dropins="dropins" dropinsEnabled="true"/>
</server>

Together with this build.gradle file you can start developing Java EE 8 applications:

apply plugin: 'war'
apply plugin: 'maven'

group = 'de.dplatz'
version = '1.0-SNAPSHOT'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    jcenter()
}

dependencies {
    providedCompile 'javax:javaee-api:8.0'
    testCompile 'junit:junit:4.12'
}

war {
    archiveName 'webapp.war'
}

task deployToWlp(type: Copy, dependsOn: 'war') {
    dependsOn 'build'
    from war.archivePath
    into "${System.env.wlpProfileHome}/dropins"
}
