Problem

Default error messages reveal information about system and it's folder structure.

Solution

Customizing Tomcat error pages is described below.

Edit the following file.
1. /usr/local/ubisecure/ubilogin-sso/ubilogin/config/tomcat/conf/web.xml
Add the lines below to the end of the file, but within the XML markup. The error message must be customized separately for each error code, as it is done below.
1. <error-page>
  <error-code>400</error-code>
  <location>/error.html</location>
  </error-page>
  <error-page>
  <error-code>401</error-code>
  <location>/error.html</location></error-page>
  <error-page>
  <error-code>403</error-code>
  <location>/error.html</location>
  </error-page>
  <error-page>
  <error-code>404</error-code>
  <location>/error.html</location>
  </error-page>
  <error-page>
  <error-code>405</error-code>
  <location>/error.html</location>
  </error-page>
  <error-page>
  <error-code>408</error-code>
  <location>/error.html</location>
  </error-page>
  <error-page>
  <error-code>410</error-code>

  </error-page>
  <error-page>

  </error-page>
  <error-page>

  </error-page>
  <error-page>

echo "ERROR - Customize this text as desired" > /usr/local/ubisecure/ubilogin-sso/ubilogin/webapps/ROOT/error.html
