I had also updated web.xml, but I had to make the <c:out/> changes you recommended, and I ended up commenting-out the language selections on the login page because I couldn't get <c:out> working correctly with them, and we only need English for now. I really wish I didn't have to use Weblogic but that's life :)
Thanks again,
Mark

A quick google search seems to indicate that that exception appears when the document is not saved in the proper encoding. I'm no sure if that's the problem in your case.
Also, did you update your web.xml to use the proper Servlet 2.3 spec?
These are the steps we usually recommend people take:

I have successfully configured CAS to authenticate against our LDAP server and it works properly with Tomcat 5.0. I am trying to deploy CAS 3.0 to Weblogic 8.1 SP5, which is a Servlet 2.3 container. When I deploy it out-of-the-box, I get errors about java.lang.NoClassDefFoundError: javax/servlet/jsp/el/ELException
I replace jstl-1.1.2.jar and standard-1.1.2.jar in the cas.war file and redeploy, but now I get different errors when I try to get to the login page:
/WEB-INF/view/jsp/default/ui/casLoginView.jsp(2): Could not parse deployment descriptor: java.io.IOException: cannot resolve ' http://java.sun.com/jsp/jstl/core' into a valid tag library
probably occurred due to an error in /WEB-INF/view/jsp/default/ui/casLoginView.jsp line 2:
<form method="post" action="" + (request.getQueryString () != null && request.getQueryString().length() > 0 ? "?" + request.getQueryString() : ""))%>">
I think this is because the JSP is trying to load JSTL 1.2, which is not compatible with servlet 2.3 and weblogic, so I copied view/jsp/default to my own directory, view/jsp/omjps and changed the cas_servlets.xml to load views from this directory. I edited view/jsp/omjps/ui/includes/top.jsp to use the JSTL 1.0 instead of 1.2:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
But I now get this error (albeit in a friendly page):
A general exception occurred while trying to access CAS. Please notify your system administrator.
The Weblogic log file indicates the following error:
java.io.IOException: javax.servlet.jsp.JspException: The taglib validator rejected the page: "java.io.UTFDataFormatException: Invalid byte 2 of 4-byte UTF-8 sequence., "
