I'm experiencing the following problem with a Grails based web application.
The server (Sun App server 8.1) is not serving any CSS or Image. The application is still usable and deploys ok.
If I hit the main page of my app (index.jsp) or any other paged served by a controller and I check the html source I have the following code in my html:
<link rel="stylesheet" href="css/main.css"></link>
Then if I browse to "http://myserver/myapp/css/main.css" I'm redirected to "http://myserver/myapp/css/main.css/index.gsp" that obviously doesn't exist. Then the server serves a 404 page with the following cryptic message:
message: "null" not found.
description: The requested resource ("null" not found.) is not available.
The same warning appears in my app server log.
If I deploy the app on a 9.0 server the problem disappears.
