I have a problem with my first JSF/IceFaces (version 1.8.2) application running on JBoss 5.1.0.
I recieve an exception after a while, telling me about session problems. This is weird, because i do not use sessions in my code at all. The following logs show that none of my backing beans can be instantiated because of this error (from JBoss):

I recognized that the exception is thrown an half hour after the last user activity.
The same problem has been reported on the IceFaces forums:
http://www.icefaces.org/JForum/posts/list/7752.page
http://www.icefaces.org/JForum/posts/list/18154.page
The proposed solutions were:
This was happening for us once we set the asynchronous mode off
<!-- Specifies to the ICEfaces framework that synchronous update mode is to be
used. By default, ICEfaces uses asynchronous update mode to support
server-initiated updates (AJAX push). Setting to true will enable
synchronous update mode and disable AJAX push features. -->
<context-param>
<param-name>com.icesoft.faces.synchronousUpdate</param-name>
<param-value>true</param-value>
</context-param>
When this was false we got the nice little session timed out message.
When this was true, session timeout behaviour was stack trace.
and
In the meantime I've switched from ICEfaces 1.8.2 to what's in the svn repository at the moment (1.8.3+). And the behavior has changed. There is no crash anymore.
As to your statement that you aren't using the session anywhere, the stacktrace tells that it is attempting to create a session scoped managed bean when this exception was thrown. So you are definitely using the session :)
Update as per the comments: You should indeed definitely not assign the (request based!!) FacesContext as a static variable. Also, injecting of other beans needs to be taken place by <managed-property> in faces-config.xml. Otherwise it isn't "injecting" at all, but just manually accessing the other bean. With injecting, you're letting JSF do the work to set the other bean as a property of the current bean. An example can be found here.
The reason for the exception was in my SessionBean classes.
I asked above if the reason can be the injection of beans into another via the facesContext.
Now i give the answer my self: "Yes it can be the reason."
public class MySessionBean {
private static FacesContext facesContext = FacesContext.getCurrentInstance();
private utils.AnotherSessionBean injectedSessionBean = (utils.AnotherSessionBean) facesContext.getApplication().getELResolver().getValue(facesContext.getELContext(), null, "anotherSessionBean");
// ...
}
I felt free to instantiate the current FacesContext outside of any method or the constructor, which was not a good idea, because after the session-timeout i used the old one or mabey no session context. MySessionBean was reloaded or get a new instance of it, but it didn't refresh the FacesContext. The result of this is described above^^
Conclusion: So getting the FacesContext belongs in the codeblock of a method or constructor.
Thank you very much for your help!

I am using spring-data-mongodb dependency in my Spring MVC application. It was working fine till now but I needed to add a Class instance property to one of my domain objects. Since Mongo doesn't support persisting Class instances directly, I added custom converter for this case. I followed the instructions here: http://static.springsource.org/spring-data/data-mongodb/docs/current/reference/html/mongo.core.html#mongo.custom-converters.writer
So my converters looks like:
public class ClassReadConverter implements Converter<DBObject, Class> {
public Class convert(DBObject source){
Class entityClass = null;
try{
entityClass = Class.forName((String) source.get("entityClass"));
}catch (Exception e){
}
return entityClass;
}
}
public class ClassWriteConverter implements Converter<Class, DBObject> {
public DBObject convert(Class entityClass) {
DBObject dbo = new BasicDBObject();
dbo.put("entityClass", entityClass.getName());
return dbo;
}
}
I registered these converters using:
<mongo:mapping-converter>
<mongo:custom-converters>
<mongo:converter>
<bean class="com.test.util.ClassReadConverter"/>
</mongo:converter>
<mongo:converter>
<bean class="com.test.util.ClassWriteConverter"/>
</mongo:converter>
</mongo:custom-converters>
</mongo:mapping-converter>
<!-- MongoTemplate instance -->
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
<constructor-arg name="mongoConverter" ref="mappingConverter"/>
</bean>
Now the issue is that when the app starts and I load the first page in the app for the first time, I get an exception. If I reload/resubmit that page everything works fine. Every single page I access after that works without issues as well.
This is the write exception:
SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container

Why do I get this issue only for one page and the first time only? Its like something is not instantiated and then suddenly its all fine. Any help is appreciated!!
I am using 1.1.1.RELEASE version and even tried using 1.2.0.BUILD-SNAPSHOT as well.
I've tried to run your code with Spring Data MongoDB version 1.2.0.RELEASE and worked fine. Just to be clear - my document class is:
#Document
public class User {
#Id
private ObjectId id;
private String name;
private Class clazz;
public User(String name) {
this.id = new ObjectId();
this.name = name;
this.clazz = this.getClass();
}
}
And it worked perfectly fine - i tried it with unit test only. Maybe it's fixed with new (1.2.0.RELEASE) version?
now i am getting this error ....still i don't know how to fix
....please atleast try to solve this error ...however i can't deal to
ahead..!!!!!!!!!

it can't find your entity. add this to your sessionFactory bean declaration
<property name="annotatedClasses">

<value>com.os.springjpa.entity.Book</value>
</list>
</property>
add more values as necessary when creating more annotated entities

I have been trying to solve this issue but with no luck, can anyone help?
Any Ideas?
Thank you
The error is ocurring during the access of some JNDI resource which the name starts with "java:comp", and this resource does not exist in the server. Are you using a datasource configured in the server? What server are you using?
I'm using Spring MVC 3.0 with sitemesh and spring message bundles. For example, I have the following:
<spring:message code="nav.item.name"/>
If nav.item.name does not exist in my resource file, I receive a blank page and a JspTagException in the console, which I can't catch with my #ExceptionHandler method. I'm assuming I can't catch it because the error is part of the view rendering. I've also tried to create a custom HandlerInterceptorAdapter, and modify the web.xml both with no success. Interestingly enough, I've also used the following tag:
<fmt:message key="nav.item.name"/>
And the view shows the page, but with "???????" for the text. This is actually more acceptable to me to at least show the page, but I would rather use the spring:message tags.
My question is: How do I catch the JspTagException?

You can't use Spring's exception handling mechanism because that is higher in the call. The JSP exception occurs later.
If you set the text attribute to some value, does it show that value instead of throwing the exception?
To clear the exception, you might provide the tag with a default message (the MessageSource.getMessage(...) method has an overload taking such a defaultMessage).
If you have no default to show but still want to warn the user about missing keys (instead of having an exception thrown or a white page), why not display the actual missing code?
You can do that by using the UseCodeAsDefaultMessage property on the MessageSource bean. See here and here.
I have a very simple Spring 3 ReST web service that looks like this
#RequestMapping(method = RequestMethod.POST, value = "/user")
public #ResponseBody
UserDTO saveUser(#RequestBody UserDTO userDTO)
{
// Functionality removed as it is not needed for this example
return userDTO;
}
This web service works great. I noticed a weird issue though when I added a 'catch-all' #ExceptionHandler though. On this POST call, even though it returns correctly, it seems an exception is thrown behind the scenes somewhere. So if I add the code:
#ExceptionHandler(Exception.class)
public ModelAndView handleRemainingExceptions(Exception ex)
{
logger.error("Unhandled exception", ex);
return new ModelAndView("error");
}
I suddenly get this error:
07.06.2011 22:54:05 ERROR-ImportController: [Unhandled exception]:

Anybody know what is going on here?
The exception appears to be complaining that your request does not include a Content-Type header and therefore Spring doesn't know which MessageConverter to use to create the method parameter UserDTO.
