Updating tomcat

Thanks in advance, Gerry I assume I need to shutdown Tomcat.

Then, is there a set of directories I should just replace to perform the update? Then do I just restart Tomcat to finalize the update?

Instructions to get Intelli J up and running with continuous deployment are below.

Sometimes there is a bit of lag for this to happen but Intelli J will tell you if it has updated on the bottom.

Below is a quick walk-through on how to set this up in Intelli J.

Unfortunately the community edition doesn’t support J2EE servers like tomcat so I the only suggestion I can give is to pick up a personal copy.

Note that Java 2 SDK 1.2 or above must be installed as the following describes how to install a certificate using keytool.

Before you install your SSL certificate you must download our root certificate bundle (repository.

After some quick searching and a couple random guesses I was able to get Intelli J doing constant updates to my JSP/JS/CSS files which greatly increased my development time.

Regards, Igal Sapir Lucee Core Developer That simple approach is incomplete.

It assumes that: a) the JARs in $CATALINA_HOME/bin haven't changed b) the names of the JARs in $CATALINA_HOME/lib haven't changed c) no configuration changes are required.

In case there are differences in configs between versions, adapt your conf using https://tomcat.apache.org/migration-85.html#Tomcat_8.5.x_configuration_file_differences I agree that separating the CATALINA_HOME from CATALINA_BASE is a much better setup, but if Tomcat was not set up like that already then for a minor upgrade this complicates the process.

The simplest way to upgrade is the one I documented.


  1. For example, Java 7 with Tomcat 7 and Java 8 with Tomcat 8 are two different configurations of the Java with Tomcat platform. You cannot perform a platform update between configurations, only between versions of the same configuration, such as Java 8 with Tomcat 8 version 1.4.5 and Java 8 with Tomcat 8 version 2.0.0.

  2. First-time Tomcat user here. I installed 8.5.9months ago, and would like to upgrade to the latest 8.5.15. I see there's some documentation for updating the 8.5.x branch here, but I'm missing some context. I have a fairly simple install/application.

  3. Nov 17, 2017. If only the JAVA_HOME environment variable is set, Tomcat will run under the JRE as part of the JDK specified by the JAVA_HOME variable. Therefore, we change JRE for Tomcat by updating this variable. If both the JAVA_HOME and JRE_HOME environment variables are set, the JRE_HOME is preferred.

  4. Restarting the OES Instance of Tomcat After Applying a Tomcat Update. Whenever there is an update to Tomcat, ensure to restart the OES instance of Tomcat using the rcnovell-tomcat restart or systemctl restart novell-tomcat.service command. This loads all the latest libraries.

  5. May 9, 2014. Submit the CSR to a Certificate Authority and get your certificate; In CUCM OS Administration, certificate management, click on upload certificate; First upload the Root or Intermediate CA certificate as a tomcat-trust certificate; Then upload the certificate for the CUCM. From the CUCM CLI, restart the Cisco.

  6. Openssl pkcs12 -export -chain -CAfile gd_-in -inkey -out keystore.tomcat -name tomcat -passout passchangeit. Updating the Configuration File. When you have completed installing your certificate, you must configure your Tomcat configuration file to point to the correct pkcs12 keystore file.
