Answer 1

Anyway single sign on is done..It took lot of time to figureout but trust me if you have a mind setup that you want to do it then anyway u will succeed ..here is the solution.. Here is my updated spring-security.xml

my updated web.xml

  Spring3MVC
  
        contextConfigLocation
        
            /WEB-INF/spring-rootcontext.xml
            /WEB-INF/spring-security.xml
        
    
      
        springSecurityFilterChain
        org.springframework.web.filter.DelegatingFilterProxy
    

    
      springSecurityFilterChain
      /*
    
    
    
        org.springframework.web.context.ContextLoaderListener
    


  
    index.jsp
  

  
    spring
    
            org.springframework.web.servlet.DispatcherServlet
        
    1
  
  
    spring
    /app/*
  
 
       CAS Single Sign Out Filter
       org.jasig.cas.client.session.SingleSignOutFilter
    
 
       CAS Single Sign Out Filter
       /*
    
    
        org.jasig.cas.client.session.SingleSignOutHttpSessionListener
    

I resolved this exception javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) by copying CAS server "cacerts" file from java\jre\lib\security of CAS server to my local java\jre\lib\security and exception was smoked.
