Prior to go-live, it's important to establish custom error pages to prevent unexpected behavior from those pesky 500 HTTP status codes. Although you could perform a similar implementation using the Apache Web Server, you may also configure custom error pages using Hybris Commerce's web.xml file using the following XML snippet:
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/views/mobile/pages/error/ServerError.jsp</location>
</error-page>
<error-page>
<error-code>503</error-code>
<location>/WEB-INF/views/mobile/pages/error/ServerError.jsp</location>
</error-page>
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/views/mobile/pages/error/ServerError.jsp</location>
</error-page>
