Some more info, from the certification matrix (http://www.oracle.com/technetwork/middleware/ias/downloads/oracle-wls-certification-10gr3-matr-129284.xls)
"1. JDK 7 certification is available only with WLS 10.3.6+/FMW 11.1.1.6+. Oracle does not support use of JDK 7 with WLS 10.3.1-10.3.5/FMW 11.1.1.1.0 - 11.1.1.5.0. ..."
If you do not care about certification (and support, because that will be gone as well when running a non-certified environment) you can use the following to change the JVM.
In the setDomainEnv file (located in the ${DOMAIN_HOME}/bin directory) find the following:
BEA_JAVA_HOME="/home/oracle/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
export BEA_JAVA_HOME
SUN_JAVA_HOME=""
export SUN_JAVA_HOME
if [ "${JAVA_VENDOR}" = "Oracle" ] ; then
     JAVA_HOME="${BEA_JAVA_HOME}"
     export JAVA_HOME
else
     if [ "${JAVA_VENDOR}" = "Sun" ] ; then
          JAVA_HOME="${SUN_JAVA_HOME}"
          export JAVA_HOME
     else
          JAVA_VENDOR="Oracle"
          export JAVA_VENDOR
          JAVA_HOME="/home/oracle/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
          export JAVA_HOME
     fi
fiby adding the JAVA_VENDOR variable you can set a specific JAVA_HOME (as can be seen from the if statement above), for example,
BEA_JAVA_HOME="/home/oracle/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
export BEA_JAVA_HOME
SUN_JAVA_HOME="/home/oracle/jdk1.6.0_31"
export SUN_JAVA_HOME
JAVA_VENDOR="Sun"
export JAVA_VENDOR
if [ "${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/oracle/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
          export JAVA_HOME
     fi
fiNow the Sun JVM will be used.
