To deploy the Principal Toolbox in Apache Tomcat, a “Context Descriptor” is required. A “Context Descriptor” is simply an XML file that contains Tomcat related configuration for the application. Attached to this topic, you’ll find an example.
Deploying the Principal Toolbox in Apache Tomcat
Open Windows Explorer on the application server, and browse to the \conf\Catalina\localhost\ directory of the Apache Tomcat application. The default location of this folder is C:\Program Files\Apache Software Foundation\Tomcat 8.0\conf\Catalina\localhost\. Copy the ROOT.xml file (attached to this page) to this directory.
Open the ROOT.xml file in notepad. Change the docBase location, and point this to the application directory of the Principal Toolbox application.
