DocuWare version 7.7 replaced the Solr 4 full text engine that included Tomcat with the improved Solr 8 engine. For security, it is recommended that the default files be removed. Can this be done without affecting the DocuWare system?

Synopsis
The remote web server contains default files.
Description
The default error page, default index page, example JSPs and/or example servlets are installed on the remote Apache Tomcat server. These files should be removed as they may help an attacker uncover information about the remote Tomcat install or host itself.
Solution
Delete the default index page and remove the example JSP and servlets. Follow the Tomcat or OWASP instructions to replace or modify the default error page.
