Performance Charts must have mappings set for Java servlet pages.

Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and identify which file types are not to be delivered to a client.

By not specifying which files can and cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc.

Because Tomcat is a Java-based web server, the main file extension used is *.jsp. This check ensures the *.jsp and *.jspx file types have been properly mapped to servlets.

At the command prompt, run the following command:

# xmllint --format /usr/lib/vmware-perfcharts/tc-instance/conf/web.xml | sed 's/xmlns=".*"//g' | xmllint --xpath '/web-app/servlet-mapping/servlet-name[text()="jsp"]/parent::servlet-mapping' -

Expected result:

<servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>*.jsp</url-pattern> <url-pattern>*.jspx</url-pattern> </servlet-mapping>

If the output of the command does not match the expected result, this is a finding.

Navigate to and open:

/usr/lib/vmware-perfcharts/tc-instance/conf/web.xml

Inside the <web-app> parent node, add the following:

<servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>*.jsp</url-pattern> <url-pattern>*.jspx</url-pattern> </servlet-mapping>

Restart the service with the following command:

# vmon-cli --restart perfcharts
