Issue/Introduction

Is it possible to remove the default Tomcat error page for Service Desk Manager (SDM)

Environment

Service Desk Manager 14.x and 17.x

All Supported Operating Systems

Resolution

Tomcat's default 404 error page has a minor security concern.

In a web browser, try accessing the SDM UI. For example http://<SD server hostname>:<port#>/abc

Note: instead of the correct SDM URL, http://<SD server hostname>:<port#>/CAisd/pdmweb.exe, a wrong URL was used to generate the Tomcat 404 error.

The default Tomcat error page exposes the Tomcat version that SDM is using.

Perform the following to remove the default Tomcat error page:

1. On the SDM server, make a backup copy of the NX_ROOT\bopcfg\www\CATALINA_BASE folder

2. Copy the NX_ROOT\bopcfg\www\CATALINA_BASE\webapps\CAisd\html TO NX_ROOT\bopcfg\www\CATALINA_BASE\webapps\ROOT folder

3. Go to NX_ROOT\bopcfg\www\CATALINA_BASE\conf folder, edit the SERVER.XML file with a text editor and add the following entry at the end of the file before the </Host> line

<Valve className="org.apache.catalina.valves.ErrorReportValve" showReport="false" showServerInfo="false"/>

4. Save the file

5. Go to NX_ROOT\bopcfg\www\CATALINA_BASE\webapps\ROOT\WEB-INF folder, edit the WEB.XML file with a text editor and add the below four (4) lines BEFORE the line containing </web-app>

<error-page>
<error-code>404</error-code>
<location>/html/errpage.html</location>
</error-page>

6. Save the file

7. Go to NX_ROOT\bopcfg\www\CATALINA_BASE\webapps\CAisd\WEB-INF folder, edit the WEB.XML file with a text editor and add the below four (4) lines BEFORE the line containing </web-app>

<error-page>
<error-code>404</error-code>
<location>/html/errpage.html</location>
</error-page>

8. Save the file

9. Restart the SDM service

After the above changes, when the SDM URL is accessed via http://<SD server hostname>:<port#>/abc, a screen similar to the following will appear (that does not have the Tomcat version listed)
