Hi,
Deploy web agent option pack on Tomcat is documented in CA SSO bookshelf.
Set Up JBOSS or Tomcat to Work with Federation Web Services - CA Single Sign-On - 12.52 SP1 - CA Technologies Documentat…
The steps are largely the same, if there are differences, then it will be related to the version of Tomcat or JBoss, or the choice of application server itself.
Have not done it personally myself on Tomcat, but believe should be very similar.

Thanks,
Hongxu
