There are 3 ways to get the Tomcat version information.

• Check the %_envision%\logs\pi_webserver.log file and find the line contains Apache Tomcat.
   
  For example:

  Mar 12, 2012 12:50:39 PM org.apache.catalina.core.StandardEngine:INFO: Starting Servlet Engine: Apache Tomcat/6.0.28

   
• Refer to the ServerInfo.properties file within the tomcat-catalina.jar file.
  1. Navigate to the bin directory.

     cd %_envision%\bin

  2. Open tomcat-catalina.jar with a tool capable of unzipping the .jar file.
  3. Look in the file tomcat-catalina.jar for org\apache\catalina\util\ServerInfo.properties.
      
     For example:

     server.info=Apache Tomcat/6.0.28

      
• Run a Java command to show the Tomcat version.

  java -cp %_envision%\bin\tomcat-catalina.jar org.apache.catalina.util.ServerInfo
