Whats the minimum required JDK version?
JDK 1.4 is the minimum version required. MapViewer will not work with JDK 1.3 or any earlier version. Also note that if you are using a standalone OC4J instance, you must start it using the Java executable that is under your JDK installation’s top bin directory. The java executable under the jre/bin directory will NOT work with OC4J.
