JDK 8 support at DIY cartridge in OpenShift

Question

I know WildFly cartridge doesn\'t have JDK support, but can I somehow install Java 8 at experimental DIY cartridge? java-1.7.0 is the latest version available at /usr/lib .<

Answer 1

Hi I want to update the answer above, since I had the same need to update the JDK for my Vert.x application. Since it's totally written in Java8 (Vert.x code looks much better with it) I started to experiment a little with Openshift, until I met the issue that juan reported.

However I had to fix some stuff and updated to JDK1.8u20:

// connect with SSH to your application, then
cd $OPENSHIFT_DATA_DIR 
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u20-b26/jdk-8u20-linux-x64.tar.gz
tar -zxf jdk-8u20-linux-x64.tar.gz
export PATH=$OPENSHIFT_DATA_DIR/jdk1.8.0_20/bin:$PATH
export JAVA_HOME=$OPENSHIFT_DATA_DIR/jdk1.8.0_20/

// then depending on your cartridge you need to exec the following command
echo $JAVA_HOME > $OPENSHIFT_{cartridge}_DIR/env/JAVA_HOME

// in my case was
// echo $JAVA_HOME > $OPENSHIFT_VERTX_DIR/env/JAVA_HOME
// for Wildfly I presume it is
// echo $JAVA_HOME > $OPENSHIFT_WILDFLY_DIR/env/JAVA_HOME
