mvc:resources leads to ClassCastException - java

I have a Spring MVC webapp that should serve static resources.
Therefore I have the following spring configuration:
<mvc:resources location="/resources/" mapping="/resources/**"/>
But each request to a resource leads to the same ugly ClassCastException:
java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.core.io.Resource

I tried it with version 3.1.0.RELEASE and 3.0.4.RELEASE of the spring framework and observed the exact same behavior.

You may be missing mvc:annotation-driven in your configuration, that is the one which registers the property editor to transform from string to a resource, that is likely causing this error message for you.

This is really weird, but the problem seems to be, that I had defined a conversion service like this:
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="converters">
<list>
<bean class="com.example.CustomConverter" />
</list>
</property>
</bean>
Which was referenced here:
<mvc:annotation-driven conversion-service="conversionService" />
Turns out if I change the bean id to something different like f. e. cs it works fine. This is really strange as the same id is used in the documentation and the showcases.

Could not initialize class org.springframework.jdbc.core.StatementCreatorUtils

My app does not include the org.springframework.ws dependency. It seems to be a jdbc issue.
Writing a web app and practicing security. this message comes up when I try to login to a mysql database called testdatabase.

Once I click my login button the error occurs. Similar questions on stackoverflow seem to indicate a dependency problem but all dependencies seem to be in place.
I got the same error when I included org.springframework.core-3.1.0.M2.jar in my project. I looked inside the jar and opened org.springframework.jdbc.core.StatementCreatorUtils class.I found that it is using a class SpringProperties which is not part of above jar.
I replaced above JAR with spring-core-4.2.0.RELEASE.jar and it started working.
I didn't do anythin apart from adding this jar file to my lib directory for my project spring-core-4.0.6.RELEASE.jar, alternatively we can add this to our build path. I hope this helps.

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";
}
The code for the actual entities can be found on a file sharing site by clicking the following links:
The code for the Encounter entity can be found at this link.
The code for the Provider entity can be found at this link.

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.

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.

I searched for hours for the reason but I didnt find it.
I also tried to add portal-impl.jar to my lib/ folder, but that didnt help and is not nice ;)
Please say I should use the new version, because I cannot change it -> customer is king
Thanks for any help!
It seems like a classLoader issue, in liferay there are different class-loaders like (rough explanation):
Plugin Class Loader: Loads the classes for plugins i.e. from '/my-portlet/WEB-INF/lib/'
Portal Class Loader: Loads the portal classes from portal-impl.jar
Global Class Loader: Loads the server classes i.e. classes from ../tomcat-7.0.27/lib/ext/
So there are different ways to load classes for DynamicQuery from one classLoader into another.
Following are the ways in which you can use DynamicQuery based on where the implementation class is located:
If the Implementation class is in your custom portlet then: Don't use a special classloader - it should work out-of-the-box.
If the Implementation class is part of the portal (i.e. from portal-impl.jar like User, Role or Group or as in your case DLFileEntry) then use the following:
Classloader loader = PortalClassLoaderUtil.getClassLoader();
DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class, loader);
If the implementation class is in another portlet then use the following:
ClassLoader classLoader = (ClassLoader) PortletBeanLocatorUtil.locate(ClpSerializer.SERVLET_CONTEXT_NAME,"portletClassLoader");
DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class, classLoader);
So to answer your question: The 2nd-method should work for you.
Information reproduced from the Liferay forum post
Try the following code:
DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class, DLFileEntry.class.getClassLoader());
For me it worked.
In my case we are using custom table.
I am getting same error whenever I tried to fetch data from my EntityServiceImpl class.
Where Entity is name of my table.
Here we are exposing our liferay service.
Issue resolved by using code
ClassLoader classLoader = (ClassLoader) PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(),"portletClassLoader");
DynamicQuery query = DynamicQueryFactoryUtil.forClass(Entity.class, classLoader);
But use ClpSerializer.getServletContextName() instead of ClpSerializer.SERVLET_CONTEXT_NAME.
As mentioned by kgiannakakis.

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.
