Cannot deploy cas-overlay 6.4 in external Tomcat 9.0.59

[Adam Cooney]

Hi,

We're having some trouble deploying the v6.4 of the overlay in an external tomcat. Currently we have:

Added to the gradle dependencies:

implementation "org.apereo.cas:cas-server-webapp:${project.'cas.version'}"

Modified gradle.properties to remove the embedded container:

appServer=

Ran "./gradlew clean build" to make the war and then put it into the Tomcat webapps directory. At the moment, the output is:

Mar 11, 2022 12:57:59 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive [/home/adam/ApacheTomcat/webapps/cas.war]

I have limited experience so far using spring boot but it looks to me like spring boot isn't even running. If I go to the application at localhost:PORT/cas/ I see a 404 page:

Type Status Report

Message The requested resource [/cas/] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

The application does run fine using the embedded Tomcat, but we would like to run them in externalised ones. Are we missing something obvious? I also noted the MANIFEST.MF contains:

Manifest-Version: 1.0
Main-Class: org.springframework.boot.loader.WarLauncher
Start-Class: org.apereo.cas.web.CasWebApplication
Spring-Boot-Version: 2.5.4
Spring-Boot-Classes: WEB-INF/classes/
Spring-Boot-Lib: WEB-INF/lib/
Spring-Boot-Layers-Index: WEB-INF/layers.idx

Any help would be appreciated - we have also tried in Tomcat 10.0.17 but have not tried any other CAS versions of the overlay other than 6.4. We were following these instructions: https://apereo.github.io/cas/6.4.x/installation/Configuring-Servlet-Container-External.html

Regards

Adam,

I do not have cas-server-webapp in my build.gradle. Try removing it. The project should be functional without having to make any modifications.

Note, if you are just starting a deployment, use version 6.5

HI,

I have upgraded to 6.5. I actually found the problem; there were some duff configuration files in Tomcat which prevented it from deploying.
