If you want to run Tomcat on IPv6 loopback address, add address attribute to the AJP connector in server.xml, shown below, and restart the ColdFusion instance.Īlternatively, you can also change the address using which web server uses to connect to the Tomcat instances. The network issue between web server and Tomcat may occur if Tomcat runs on, for example, IPv4 loopback (127.0.0.1) and the web server tries to connect using IPv6 loopback address. If the AJP connector binds to to 0:0:0:0:0:0:0:1 (IPv6), the log records: If the AJP connector binds to 127.0.0.1., the log records: You can check this by looking at the coldfusion-out.log file. INFO: Starting ProtocolHandler Ĭheck whether AJP port is open using a command like netstat.Ģ. Check whether the web server and Tomcat can communicate.ĬoldFusion and web server are on the same machineīased on your /etc/hosts setup, Tomcat can bind to either 127.0.0.1 (IPV4 ) or ::1 (IPv6) or any configured address. Check ColdFusion logs for below messages:Ħ:27:39 PM start Ensure that Apache Tomcat AJP connector starts without any issue. From this update, the AJP connector will bind to localhost address (127.0.0.1 or ::1, depends on the machine) by default, if the address attribute is not specified.ĬoldFusion and web server are not on the same machineġ. Also, change your firewall configuration such that only trusted hosts such as web server will be allowed to access the AJP connector.īefore this update, the AJP connector could bind all the interfaces (0.0.0.0) on the machine on which ColdFusion runs. Therefore, the remote web server is unable to communicate with Tomcat.Ĭonfigure each ColdFusion instance with Tomcat IP address so that Tomcat can be accessed over remote connector.

For example,īefore installing the update, ColdFusion instance ran on 0.0.0.0 (all interfaces), but now it binds to localhost loopback address. If you have multiple instances, after updating all the instances, copy secret from each instance to worker.properties. Add back any custom changes made to the worker.properties file after reconfiguring the connector.Īfter updating the ColdFusion instance, ColdFusion configures AJP connector in the instance with a random secret.Ĭopy the secret from instance to worker.properties.

Microsoft Windows 8.1, Windows 10, Windows Server R2 2012, and Windows Server 2016 users must use the “Run as Administrator” option to launch wsconfig tool at /config/ wsconfig /backup.Windows users can launch the ColdFusion Administrator using Start > All Programs > Adobe > Coldfusion 2018 > Administrator.

The update can be installed from the Administrator of a ColdFusion instance or through the command-line option.For any questions related to updates, see this FAQ.

Also, Tomcat requires that the AJP connector must be configured with a secret otherwise the AJP connector won't start (unless secretRequired=false is added to the AJP connector in server.xml).įor instructions on how to install this update, see Server Update section. When you are applying this update, we add a random secret to the server.xml AJP connector unless it is already configured. If you are not using any web server and are using an in-built web server configuration, you can completely comment out or remove the AJP connector from the server.xml configuration.īefore this update, the AJP connector could bind all the interfaces (0.0.0.0) on the machine on which ColdFusion runs. From this update, the AJP connector will bind to localhost address (127.0.0.1 or ::1, depends on the machine) by default, if the address attribute is not specified. If you are using a web server or connector configuration set up, you must make sure that the Port and IP address on which the AJP is running is only available to the web server. It is insecure (clear text transmission) and assumes that your network is safe. AJP is a highly trusted protocol and must never be exposed to untrusted clients. A configuration issue with AJP Protocol was fixed in this update which affects ColdFusion 20 along with a few JEE application servers, which use AJP such as Tomcat, JBoss, and Wildfly.ĬoldFusion uses Tomcat as application server and uses AJP connector to allow web servers, such as, IIS and Apache to use AJP Protocol connector for communication.
