How to upgrade my Apigee Edge OPDK from Java 6 to Java 7  

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.

[root@standalone share]# ls -l

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:
