Custom casLoginView - problem calculating URLs

[Pedro Rosas]

Hi all,

I'm facing a weird issue on the URL calculation.

I get different outputs for the same inputs...

On my custom "casLoginView.html" I have the following image:

<img th:src="@{/themes/xpto/images/image.svg}"></img>

On runtime this is replaced by:

<img src="/prefix/themes/xpto/images/image.svg" />   -- This path doesn't exist... The correct one should be "/prefix/cas-overlay/themes/...."

---------

But... On my custom "layout.html" I also have an image:

<img th:src="@{/themes/xpto/images/logo.svg}"></img>

But this one gets replaced by:

<img src="/prefix//cas-overly/themes/xpto/images/logo.svg" />   -- The double '//' is a bad thing... but this version works correctly and gets the correct prefix "/prefix/cas-overlay/themes/...."

-----

Do you guys have any idea why the URL replacement logic is different?

Why is the first one missing the "/cas-overlay" prefix?

Thanks in advance.

Best Regards,

  Pedro Rosas

By the way, I'm using CAS 5.3.5.

It's been a while since I messed with this stuff, but did you remember to update your custom casLoginView.html to use your custom layout.html by changing the layout:decorate attribute of the html tag from ~{layout} to ~{cas-overlay/layout}?

Hi David,

Changing it to ~{cas-overlay/layout} makes it return a 500 internal error: 

Error resolving template "cas-overlay/layout", template might not exist or might not be accessible by any of the configured Template Resolvers.

Could this be related to the cas.server.name and cas.server.prefix properties?

I tried several combinations on this, but none were successful.

I still did not understand the role of these 2 properties...

Thanks.

The cas.server.name and cas.server.prefix shouldn't matter for this. Basically cas.server.name is the URL of your server, and cas.server.prefix includes that plus the application prefix in the J2EE container. Like this:

cas.server.name:     https://casserver.yourdomain.com

cas.server.prefix:   ${cas.server.name}/cas 

cas.server.name can include ports or whatever, like:

cas.server.name:     https://casserver.yourdomain.com:8443 

As for customizing the UI, you might find this helpful:

https://dacurry-tns.github.io/deploying-apereo-cas/ui_overview.html

That's the "top" page... see the menu on the left of the page for the following sections. It's written for 5.2.x, but should be pretty much the same for 5.3.x.
