When Apigee Edge OPDK is installed, you specify the location of java when you install with the apigee-install.sh script.
# ./apigee-install.sh
Found certified OS
Please enter Oracle JDK 1.6 home (/usr/java/default): /usr/jdk1.6.0_35
java environment is OK (arch, vendor, version)
Java version verified.
...
The installer simply creates a symbolic link from /<ApigeeRoot>/apigee4/share/jdk to the location where you have installed java.

To upgrade to Java 7 from Java 6, follow these steps:
1. stop your apigee processes on your nodes:
/<ApigeeRoot>/apigee4/bin/all-stop.sh
2. delete the symbolic link to the java 6 installation
cd /<ApigeeRoot>/apigee4/share
rm jdk
3. create a symbolic link to the java 7 install
ln -s /usr/jdk1.7.0_75 /opt/apigee4/share/jdk
Here is the expected output when running ls -l:

4. restart your apigee processes on your nodes
/<ApigeeRoot>/apigee4/bin/all-start.sh
<end>
I have added this procedure to the Edge Operations Guide.
