Installing the HTTP Module for Tomcat
This topic describes how to install the HTTP session management module for Tomcat.
- If you have not already installed Tomcat, download the desired version from the Apache Website and install it.
Following the Apache Tomcat convention, this page assumes the CATALINA_HOME environment variable is set to the root directory of the “binary” Tomcat distribution. For example, if Apache Tomcat is installed in
Define $CATALINA_HOME if it is not already defined.
For development purposes, you may find it helpful to establish manager-level access to Tomcat. To do so, edit the file
$CATALINA_HOME/conf/tomcat-users.xml. Uncomment the following line, and replace the
<must-be-changed>placeholder with a password of your own choosing:
<user username="admin" password="<must-be-changed>" roles="manager-gui"/>
This creates an admin/password credential you can use to view system information when following links from the Tomcat home page.
The HTTP Session Management Module for Tomcat is included in the Tanzu GemFire installation package. After you install VMware Tanzu GemFire for Kubernetes Cluster, you will find the module in the
tools/Modulesdirectory of the installation with a name of the form
Apache_Geode_Modules-SERVER-VERSION-Tomcat.zip, where SERVER-VERSION is the VMware Tanzu GemFire for Kubernetes Cluster version number.
Set your current working directory to the
$CATALINA_HOMEdirectory (or wherever you installed the application server) and unzip the HTTP Session Management Module. This adds jar files to the
libsubdirectory and XML files to the
cd $CATALINA_HOME unzip $GEODE_HOME/tools/Modules/Apache_Geode_Modules-SERVER-VERSION-Tomcat.zip
Copy the following jar files from the Tanzu GemFire
libsubdirectory to the
libsubdirectory of your Tomcat server (
$CATALINA_HOME/lib), adding version numbers to the filenames as needed:
- commons-io jar
- commons-lang jar
- commons-validator jar
- fastutil jar
- geode-common jar
- geode-core jar
- geode-logging jar
- geode-management jar
- geode-membership jar
- geode-serialization jar
- geode-tcp-server jar
- javax.transaction-api jar
- jgroups jar
- log4j-api jar
- log4j-core jar
- log4j-jul jar
- micrometer-core jar
- shiro-core jar
