CAS Client Compilation Error

[Steve Cheung]

Hi all,

I am using the JDK 11 to build the package but encounter this compilation error. The code is from https://github.com/apereo/java-cas-client.

Do anyone has idea about how to solve it? Many thanks.

Regards, Steve

Hi Steve,

Have not tried building this using jdk11.

However, looking at this line here: https://github.com/apereo/java-cas-client/blob/cas-client-3.6.1/pom.xml#L94

It seems the project is built using jdk 8, so I am not sure if it supports jdk 11.

Hi Andy,

Thanks for your prompt reply.

When I used JDK 1.8 to compile, however, it prompts another error. I am using the master branch to build. Did you build successfully before? 

Beside the compilation error, I have another question. I am helping to move all client's J2EE web app to private cloud running on Tomcat. It is container base, so one application will be hosted in one container.  In order to keep the SSO across multiple tomcats, so I am looking to integrate this CAS client into Tomcat to avoid too many code changes on application. Am I on the right direction?

Steve,

From a security point of view, you want logins to each application to be separate. One application per tomcat is ok, but if two application on one tomcat, then user has access to both. However, I suspect that mod_auth_cas works this way.

Let us know how this goes. It could simplify deployment because CAS client would be part of the tomcat playbook and application configuration would not need to include CAS bits.

What would happen in a proxy setup? The application would need access to the PGT but this would be help by tomcat.

Hi Ray ,

Thanks for your reply. For my project case, one application will be hosted on one container only. And once the user logged in application A and he/she is able to access application B in other tomcat directly.

Thats's why I am looking for install the cas client in each tomcat in future. For the mod_auth_cas, since I am not familiar, any document / technical can be shared to me?

Thanks, Steve

Steve,

I have not used mod_auth_cas myself, here is the code base, https://github.com/apereo/mod_auth_cas
