DRAFT KB-XXXX Tomcat fails with "Unable to find [jdbc]"

Symptoms

Tomcat fails with the following error in <APPIAN_HOME>/logs/tomcat-stdOut.log:

ERROR org.hibernate.connection.DatasourceConnectionProvider - Could not find datasource: jdbc/AppianDS
javax.naming.NameNotFoundException: Name [jdbc/AppianDS] is not bound in this Context. Unable to find [jdbc].

Cause

When the configure script is run, the content in tomcatResources.xml.<ENVIRONMENT> is copied to suite.xml in <APPIAN_HOME>\tomcat\apache-tomcat\conf\Catalina\localhost.

This error occurs if this content does not copy over correctly or if suite.xml is configured improperly.

Action

1. Ensure tomcatResources.xml.<ENVIRONMENT> is configured according to installation documentation and manually copy the entire contents of it to suite.xml in between the lines:
   <!-- BEGIN DATASOURCE -->
<!-- END DATASOURCE -->
2. Restart Tomcat.

Affected Versions

This article applies to Appian 18.3 and later.
