Since dockerfile/java could point to some other JVM, modified both Dockerfiles to include the following line instead specifically calling for java7 (otherwise the path to /usr/lib/jvm/java-7-oracle will not be found in the docker container created for weblogic)

 from dockerfile/java:oracle-java7
