JAVA_HOME is what you need:

jonathan:~,7:36am> unsetenv JAVA_HOME
jonathan:~,7:36am> java -version
openjdk version "1.6.0_32"
OpenJDK Runtime Environment (build 1.6.0_32-b27)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
jonathan:~,7:36am> setenv JAVA_HOME /usr/local/openjdk7
jonathan:~,7:36am> java -version
openjdk version "1.7.0_25"
OpenJDK Runtime Environment (build 1.7.0_25-b15)
OpenJDK 64-Bit Server VM (build 23.21-b01, mixed mode)
