In this post, we discuss how to upgrade the latest minor version of JDK(Java Development Kit) of the ColdFusion server. ColdFusion can run only on top of JDK or JRE with Server VM. Oracle also started providing separate download link for JRE and Server JRE. ColdFusion only works with JDK or Server JRE and not with Client JRE [For more details refer article].
There are two ways to change the JDK or Server JRE of the ColdFusion server:
- Using ColdFusion administrator console.
- By changing the JDK or Server JRE path from the jvm.config file.
1. Using ColdFusion administrator console.
- Download the latest minor version of the supported JDK or Server JRE.
- Install the JDK or Server JRE.
- Navigate to ColdFusion Administrator > Server Settings > Java and JVM section.
- Browse the path to the JDK or Server JRE from the “Java Virtual Machine Path” textbox which you intended to use with ColdFusion.
- Click “Submit Changes”.
- Restart the ColdFusion Application service.
2. By changing the JDK or Server JRE path from the jvm.config file
- Download the latest minor version of the supported JDK or Server JRE.
- Install the JDK or Server JRE.
- Open jvm.config file located at <cf_install_root>cfusionbin.
- Change the value of java.home to the JDK or Server JRE path. [For example: C:\Program Files\Java\jdk1.7.0_25\jre or C:/Program Files/Java/jdk1.7.0_25/jre]
- Save the changes to the jvm.config file.
- Restart the ColdFusion Application service.
Important Note:
- It is not recommended to change the JDK version on the production servers without any prior testing in the staging environment.
- Any SSL certificates added to the previous JDK will also need to be re-added to the new JDK(cacerts) file.
