This error is troubling me since last 4 days...Please help.. I don't know if the error is in my server configuration or in the application?

Here is what i ve done...

My CAS server runs on Tomcat at port no 8443
Here is the configuration sever.xml for tomcat
Code:
<Connector SSLEnabled="true" clientAuth="false" keystoreFile="E:/my.keystore" keystorePass="password" maxThreads="150" port="8443" protocol="HTTP/1.1" scheme="https" secure="true" sslProtocol="TLS"/>
I ve created my keystore file using keytool and stored at e:\ as shown.

In chrome, when i run the application, i am redirected to the CAS login page.
But when i enter username and password, i get the error java.security.cert.CertificateException: No name matching localhost found error
Here is my security.xml
Code:
	<security:http entry-point-ref="casAuthenticationEntryPoint"
		auto-config="true" use-expressions="true">
		<security:intercept-url pattern="/**" access="hasRole('ROLE_USER')"></security:intercept-url>
		<security:custom-filter position="CAS_FILTER" 
			ref="casAuthenticationFilter"></security:custom-filter>
 </security:http>
