There is a small example here: Middleware Snippets: WebLogic, Coherence and the G1 Collector
Note that this goes the other way around, from JRockit to Oracle JDK. In your case you can set the JAVA_VENDOR to Oracle (instead of Sun) and enter the BEA_JAVA_HOME value.
There is something like the following in the setDomainEnv file (located in the ${DOMAIN_HOME}/bin directory):
WL_HOME="/home/weblogic/weblogic12.1.1/installation/wlserver_12.1"
export WL_HOME
BEA_JAVA_HOME="/home/weblogic/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
export BEA_JAVA_HOME
SUN_JAVA_HOME="/home/weblogic/jdk1.7.0_11"
export SUN_JAVA_HOME
JAVA_VENDOR="Sun"
export JAVA_VENDOR
if [ "${JAVA_VENDOR}" = "Oracle" ] ; then
  JAVA_HOME="${BEA_JAVA_HOME}"
  export JAVA_HOME
else
  if [ "${JAVA_VENDOR}" = "Sun" ] ; then
  JAVA_HOME="${SUN_JAVA_HOME}"
  export JAVA_HOME
  else
  JAVA_VENDOR="Oracle"
  export JAVA_VENDOR
  JAVA_HOME="/home/weblogic/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
  export JAVA_HOME
  fi
fi
By changing the JAVA_VENDOR to the right one, you can see the in the 'if' statement JAVA_HOME is set by using either SUN_JAVA_HOME or BEA_JAVA_HOME
The nodemanager.properties also has properties where JAVA_HOME is set (javaHome and JavaHome).
