proxy setting questions

[Edward Chen]

I have Tomcat and cas 3.2.1 set up and up and running.  Now I want to 
know how the proxy works in CAS

Before I edit anything in web.xml and my test.jsp, everything just 
working fine. But, after I dump the following code in test.jsp

"
<%=request.getRemoteUser()%>

<%@ taglib prefix="cas" uri="/WEB-INF/castools.tld" %>

<cas:auth id="netid" scope="session"/>
"

I experience two problems
1. It redirect me to 
https://secure.its.yale.edu/cas/servlet/login?service=http://edwardcwin.wri.wolfram.com:8080/Recruiting/test.jsp, 
not to
https://edwardcwin.wri.wolfram.com:8443/cas/login?service=http://edwardcwin.wri.wolfram.com:8080/Recruiting/test.jsp
2. If I manually change to 
https://edwardcwin.wri.wolfram.com:8443/cas/login?service=http://edwardcwin.wri.wolfram.com:8080/Recruiting/test.jsp, 
I throw out an exception after I went through cas login page

org.apache.jasper.JasperException: Exception in JSP: /test.jsp:6

3: 
4: <%@ taglib prefix="cas" uri="/WEB-INF/castools.tld" %>
5: 
6: <cas:auth id="netid" scope="session"/>

8:

Here it the portion of my web.xml that I insert to


....
   <servlet>

    <servlet-name>ProxyTicketReceptor</servlet-name>

    <servlet-class>edu.yale.its.tp.cas.proxy.ProxyTicketReceptor</servlet-class>

   </servlet>

 

  <servlet-mapping>

    <servlet-name>ProxyTicketReceptor</servlet-name>

    <url-pattern>/CasProxyServlet</url-pattern>

  </servlet-mapping>

...

It seems to me that the process throw out the exception before this web.xml portion.

Can you tell what it's wrong?
