The BonCode connector is bundled with the Railo and Lucee CFML engines. If you need to upgrade the connector you can follow the instructions here so-long as you used the Railo/Lucee installer for the initial install.
First make a backup of the connector settings and install files. They are located in c:\windows\BonCodeAJP13.settings and [Railo/Lucee install]\AJP13 .
The actual upgrade involves removing the existing connector and then installing the new version.
a) MAKE A BACKUP: c:\windows\BonCodeAJP13.settings and [Railo/Lucee install]\AJP13 .
b) Uninstall the existing connector: Run the Uninstallation program accessible in your control panel (Program and Features). Keep IIS features when prompted.
c) Download new version package (zip file) from distribution point (http://www.boncode.net/boncode-connector)
d) Unblock zip file: (http://boncode.net/connector/webdocs/Tomcat_Connector.htm#_Toc520189772) the downloaded .zip and, then, extract files.
e) Copy the extracted files OVER the existing files in your Railo/Lucee install (e.g. [install]\AJP13 where [install] is the directory you have installed Railo\Lucee.
f) Run the connector_setup.exe program and acknowledge the warning that “ALL YOUR INPUTS WILL BE IGNORED.” If you do not see this warning do not proceed. You have not completed steps a-e correctly.
g) from your initial backup in step a) copy your original setting file back from backup overriding the one located here c:\windows\BonCodeAJP13.settings
h) Stop/Start IIS.
