Solution

The installation process is the same for all platforms and installation choices. Use the ColdFusion 8 Administrator to install hot fix jar files.

Download hf801-71362.zip (19k) and extract the hf801-71362.jar.
Open the ColdFusion 8 Administrator, and then select the System Information page.
Next to the Update File box, click Browse and browse to the extracted jar file.
Select the hf801-71362.jar file, and then click Submit.
Restart ColdFusion.

The hf801-71362 hot fix JAR file does not need to be retained after installing it with the ColdFusion Administrator. The file has been copied into the correct location.

The hf801-71362.jar hot fix file will appear as a new entry in the System Information classpath list.

Hot fix jar files are installed in the cf_root\lib\updates directory. After stopping the ColdFusion 8 application server, delete a specific jar file from the updates directory in order to uninstall that hot fix.
