Disabling Tomcat's development mode is an important step before moving your Hybris Commerce application into production.
Why is this an important pre-production step? When Tomcat is in development mode, it checks JSPs (Java Server Pages) timestamps for modifications. When a modification is detected, Tomcat will then recompile the JSP in the background. This process is wonderful for development as it helps with debugging, but will degrade production performance.
Here are the steps to disable Tomcat's development mode:
1. Open and the web.xml (config/tomcat/conf/web.xml)
2. Once the file is open, please ensure your web.xml file has its development parameter value set to false
3. Save the web.xml
4. From the hybris/bin/platform directory, run the "ant all" command
5. Then perform the correct Hybris start command for your environment
