Do not use Apache Tomcat packages and APIs

This rule scans Java files to detect the use of the following Apache Tomcat proprietary packages:

• org.apache.tomcat
• org.apache.catalina
• org.apache.coyote
• org.apache.el
• org.apache.jasper
• org.apache.jk
• org.apache.juli
• org.apache.naming

When your application uses classes in these packages, the code must be changed to use Java development kit (JDK) provided APIs, WebSphere Application Server provided APIs, or open source APIs.

Evaluate the code using the Tomcat-specific API, and change it to use a non-proprietary API or a WebSphere Application Server API.

For additional information see:

• Apache Tomcat 8.0 API Java documentation.
• Apache Tomcat 9.0 API Java documentation.
