One of most important upgrade of fedora 9 is OpenJDK. Red Hat work with Sun using IcedTea background to offer to users an open source implementation of Java Development Kit.
To use this JDK on your application like Liferay or Xwiki, you must define environments variables JAVA_HOME and JRE_HOME.
For my part, I add a file on /etc/profile.d named java.sh and contain
export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64
export JRE_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64
So now, with OpenJDK and Eclipse, Fedora is a ready developer platform without add-on. Developer Spin will be more attractive.
