# Set up JNDI connections for the Pentaho Server Instructions for adding JNDI connections vary depending on which web application server you are using. * If you installed the Pentaho Server using the Pentaho Installation Wizard, you are using a [Tomcat](http://tomcat.apache.org/) web application server. * If you installed the Pentaho Server using the manual installation method, you are using either a [Tomcat](http://tomcat.apache.org/) or [JBoss](http://www.jboss.org/overview/) web application server. If you installed the Pentaho Server using the manual installation method, then you specified data connections to your Tomcat or JBoss web application server. If you want to modify existing connections or define more JNDI connections, perform the appropriate set of instructions below. This material is only for IT administrators who know where data is stored, how to connect to it, details about the computing environment, and how to use the command line to issue commands for Microsoft Windows or Linux. You should also know how to install a database and a web application server. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
