Hi guys,
I got CAS running successfully on my Tomcat container. i.e.,
http://localhost/cas/login gives me the login page and when I enter the
same username and password, I am logged in successfully into CAS.
However, I tried to get CAS working using a filter for the sample JSP
examples shipped with Tomcat. I edited the web.xml under jsp-examples
directory and added the following...
<description>
JSP 2.0 Examples.
</description>
<display-name>JSP 2.0 Examples</display-name>
<filter>
<filter-name>CAS Filter</filter-name>
<filter-class>edu.yale.its.tp.cas.client.filter.CASFilter</filter-class>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>
<param-value>https://localhost/cas/login</param-value>
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.validateUrl</param-name>
<param-value>https://localhost/cas/proxyValidate</param-value>
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
<param-value>localhost</param-value>
</init-param>
</filter>
Now, when I try to access any jsp page under jsp-examples, I am being
rightly redirected to the CAS login page. When I enter the username and
password thought, I am getting a ServletException (Unable to validate
ProxyTicketValidator).
I followed the instructions on
http://www.ja-sig.org/products/cas/server/ssl/index.html and generated
the certificate and added it to the keystore. I also edited the
server.xml file under Tocmat\conf to..
<Connector className="org.apache.coyote.tomcat5.Coyote-Connector"
keystoreFile="c:\Program
Files\Java\jdk1.5.0_01\jre\lib\security\cacerts" port= "8443"
miniProcessors="5" maxProcessors="75" enableLookups= "true"
disableUploadTimeoue= "true" acceptCount= "100" debug= "0" scheme=
"https" secure= "true" cleintAuth= "false" sslProtocol= "TLS"/>
I am lost right now. Please advise. You can find the errors/exception
I've found in the Tomcat log file below.
Regards,
Shashi
