Probably is because you send a request to http and not https CAS works only with https
See what the yalle people say:
On the mailing lists we often get questions on why SSO does not seem to be working. By default, CAS only sends the single sign on cookie (CASTGC) over secure connections; in other words it is not sent over a plain HTTP channel. Without the SSO cookie CAS requires reauthentication on every request for a service ticket, which explains the lack of SSO behavior. Although it is possible to disable this behavior, we strongly encourage accessing CAS and application entry points over SSL/TLS.


I know why it happened.
You can see ticket expiration policy here. Then you know how to configure the service ticket use time.
Configuration file path:
cas\WEB-INF\spring-configuration\ticketExpirationPolicies.xml

failed to lazily initialize a collection due to no session

In a spring mvc application using hibernate, I am getting the following error message:
root cause
org.hibernate.LazyInitializationException:
failed to lazily initialize a collection of role:
org.springframework.samples.knowledgemanager.model.Encounter.providers,
could not initialize proxy - no Session
The error is being thrown when I try to access an arraylist that is a property of each object in another arraylist. Specifically, I have an arraylist of Encounter objects called encountersforday, and each of the Encounter objects has a property providers which is an arraylist of Provider objects. The error is thrown when I try to call the providers arraylist from the jsp using spring expression language as follows:
<spring:eval expression="encountersforday.get(2).getProviders()" var="myps" />
<c:forEach var="id" items="${myps}" varStatus="k">//this is the line throwing error
<spring:eval expression="id==3" var="match_id"></spring:eval>
<c:choose>
<c:when test="${match_id==true}">true</c:when>
<c:otherwise>false</c:otherwise>
</c:choose>
</c:forEach>
The code above references the following controller code:
#RequestMapping("/calendar")
public String showCalendar(#RequestParam("day") String day, org.springframework.web.context.request.WebRequest webRequest, Model model) {
String pid = webRequest.getParameter("pid");
System.out.println("............ pid is: "+pid);
model.addAttribute("pid", pid);
LocalDate mydate;
if(day.equals("")){mydate = new LocalDate();}
else{mydate = new LocalDate(day);}
System.out.println("------------------------ in controller, day of month is: "+mydate.getDayOfMonth());
AppointmentCalendar calendar = new AppointmentCalendar(mydate); // Or whatever you do to create it
List<Encounter> encountersforday = (List<Encounter>) clinicService.getEncountersForDay(mydate);
model.addAttribute("calendar", calendar);
model.addAttribute("encountersforday", encountersforday);
System.out.println("number of encountersforday is: "+encountersforday.size());
List<LocalTime> myblocks = calendar.getBlocks();
int[][] filledblocks = new int[myblocks.size()][3];
for(Integer i=0;i<encountersforday.size();i++){
System.out.println("i, encounterid, patientid, first, last, dateTime are: "+i+", "+encountersforday.get(i).getId()+", "
+encountersforday.get(i).getPatient().getId()+", "+encountersforday.get(i).getPatient().getFirstName()+", "+encountersforday.get(i).getPatient().getLastName()+", "+encountersforday.get(i).getDateTime());
for(Integer g=0;g<myblocks.size();g++){
filledblocks[g][0] = g;//blockid
if(myblocks.get(g).getHourOfDay()==encountersforday.get(i).getDateTime().getHourOfDay()){
if(myblocks.get(g).getMinuteOfHour()==encountersforday.get(i).getDateTime().getMinuteOfHour()){
int hours = myblocks.get(g).getHourOfDay();
int mins = myblocks.get(g).getMinuteOfHour();
System.out.println("found match at: "+hours+":"+mins);
filledblocks[g][1] = i+1;//encounterid
filledblocks[g][2] = 1;//segmentindex
}
}
}
}
for(int k=0;k<filledblocks.length;k++){
System.out.println("blockid, encounterid, segmentnum are: "+filledblocks[k][0]+", "+filledblocks[k][1]+", "+filledblocks[k][2]);
}
model.addAttribute("filledblocks", filledblocks);
//get list of providers for columns in calendar
List ps = (List) clinicService.findProvidersByFacilityAddressId(7);
model.addAttribute("ps", ps);
for(int g=0;g
return "appointments/calendar";
}

Somehow (it is not visible in the code you posted and doesn't terribly matter) your clientService is using a Session object to get the list of Encounter objects. That Session object has a close method which is called when the Session is finished. Once that close method is called, you cannot access lazily initialized properties unless they have already been initialized.
This trips up most people because most people do not actually open and close the Hibernate sessions themselves but have that taken care of by an underlying framework. For example, if you are using Spring you are likely using the #Transactional and #PersistenceContext annotations which are opening and closing sessions under the hood (in this case, the session is closed when the transaction ends, e.g. when you leave the scope of the #Transactional method).
Ultimately, however you are doing things, the solutions available are the same. The easiest solution is to simply mark the Encounter's provider relationship as an eager relationship (e.g. #ManyToMany(... fetch=FetchType.EAGER ...)) but this may have performance implications if there are lots of places you load Encounter objects and not Provider objects.
Another "global" solution would be to extend your transaction scope so that the processing of the JSP is actually inside your transaction for the request. This is often done by putting the start and stop of the transaction in filters. Although sometimes this does not work for people either.
A very targetted solution is to use the static method Hibernate.initialize() to initialize each object before you pass it to the JSP layer:
List<Encounter> encountersforday = (List<Encounter>) clinicService.getEncountersForDay(mydate);
for(Encounter encounter: encountersforday) {
Hibernate.initialize(encounter.getProviders());
}
There may be other solutions as well, but these are the ones that jump to mind. I hope you can make progress with this.

i m using C3P0 0.9.1 version and my C3P0 Settings as below.
cds.setDriverClass(dbdriver);
cds.setJdbcUrl(dburl);
cds.setUser(username);
cds.setPassword(password);
cds.setMinPoolSize(2);
cds.setAcquireIncrement(1);
cds.setMaxPoolSize(200);
cds.setMaxStatementsPerConnection(40);
cds.setMaxConnectionAge(20);
cds.setMaxStatements(30);
cds.setIdleConnectionTestPeriod(100);
cds.setMaxConnectionAge(60);
cds.setMaxIdleTimeExcessConnections(40);
and also application stops working. can anybody suggests me, need to change C3P0 settings ?

Please close the connection once you are done with the connection, then only the connection returns to the pool. One suggestion, you can shift to BoneCP its more active project right now and also have a good feedbacks from production. C3P0 support is not there any more.

Basically here parameters is a session parameter map. So as per java specification parameters map is immutable. But this works good for Websphere Application server.
While researching, I read a comment here that says
if this worked in WebSphere then WebSphere is not following the
specification. Either because of a bug or because it has been
explicitly configured to ignore that part of the spec.
Any alternatives? except do not remove elements from map
Also, is it possible if there is any configuration in tomcat that can make the parameter map mutable ?

How is cleared these error.please guide me.

The error message says it all:
org.apache.axis2.AxisFault: namespace mismatch require http://ws.retailer.com found http://ws.retailer.com/
One URL has a trailing backslash, the other doesn't.
You can configure your server. Here's the documentation for "Apache re-writes":
http://httpd.apache.org/docs/2.0/mod/mod_dir.html
Easier, just make sure your endpoint exactly matches the URL.
