Tomcat CAS Missing TldParser

[George Lawson-Crowson]

Hello! I'm trying to install CAS and am getting Tomcat errors saying that I'm missing the TldParser JAR. If you could help, please respond to my StackOverflow question.

Sincerely,

I have built CAS as a standalone war and deployed to Tomcat 7.latest_stable(7.0.85)  and I get a 

Caused by: java.lang.NoClassDefFoundError: org/apache/tomcat/util/descriptor/tld/TldParser

However in tomcat 8

deploys fine

I am suspecting a difference in Servlet / JSP / EL specs between tomcat 7 and 8

http://tomcat.apache.org/whichversion.html

Does anyone know of the top of their head what JEE specs (Servlet / JSP / EL) CAS 5.2+ supports?

I will Dig into the code and POMs to work it out.

It's documented here:

https://apereo.github.io/cas/5.2.x/installation/Configuring-Servlet-Container.html#external

TL;DR: Servlet v3.1 or better, so Tomcat 8.5.x or better (8.0.x is end-of-life as of June 30th of this year).

Hello all,

Thanks for the help! I installed Tomcat v8.5 following this guide and was able to get CAS running. Super excited to start digging around.

If possible I recommend adding suggested Tomcat / servlet container versions to this section of the docs.

Sincerely,

George

If you can I would roll out the application as a Spring-boot app with the embedded container that's where things are going.....
