org.jboss.weld.context.NonexistentConversationException: WELD-000321 No conversation found to restore for id 1
Hello I'm trying to find a way to catch and redirect back to the login (restore a converstion or start a new one)
in web.xml I have...
<session-config> <session-timeout>1</session-timeout> </session-config>
and
<context-param> <param-name>org.apache.myfaces.ERROR_HANDLER</param-name> <param-value>org.mcgill.phire.jsf.exception.MyExceptionHandler</param-value> </context-param>
so this will throw the
org.jboss.weld.context.NonexistentConversationException: WELD-000321 No conversation found to restore for id 1 error
I try to handle it...
in faces-config I have...
<factory> <exception-handler-factory>org.mcgill.phire.jsf.exception.MyExceptionHandlerFactory</exception-handler-factory> </factory>
public class MyExceptionHandlerFactory extends ExceptionHandlerFactory {
private ExceptionHandlerFactory parent;
// this injection handles jsf
public MyExceptionHandlerFactory(ExceptionHandlerFactory parent) {
this.parent = parent;
}
//create your own ExceptionHandler
@Override
public ExceptionHandler getExceptionHandler() {
ExceptionHandler result =
new MyExceptionHandler(parent.getExceptionHandler());
return result;
}
}
--------------------------------------------------------
@HandlesExceptions
public class MyExceptionHandler extends ExceptionHandlerWrapper {
//private static Log log = LogFactory.getLog(MyExceptionHandler.class);
private static final Logger LOG = LoggerFactory.getLogger(MyExceptionHandler.class);
private ExceptionHandler wrapped;
public MyExceptionHandler(ExceptionHandler wrapped) {
this.wrapped = wrapped;
}
@Override
public ExceptionHandler getWrapped() {
return wrapped;
}
@Override
public void handle() throws FacesException {
//Iterate over all unhandeled exceptions
Iterator i = getUnhandledExceptionQueuedEvents().iterator();
while (i.hasNext()) {
ExceptionQueuedEvent event = (ExceptionQueuedEvent)i.next();
ExceptionQueuedEventContext context =
(ExceptionQueuedEventContext)event.getSource();
//obtain throwable object
Throwable t = context.getException();
//here you do what ever you want with exception
try{
//log error
LOG.error("Serious error happened!", t);
ExceptionHandlerUtil.handleNavigationWithError("m300123");
//redirect to error view etc....
}finally{
//after exception is handeled, remove it from queue
i.remove();
}
}
//let the parent handle the rest
getWrapped().handle();
}
}

TRYING EVERYTHING HERE BUT ALWAYS AN UNHANDLED CONVERSATION

}
catch(Exception ex){
LOG.error(e.getMessage());
}*/
}
}
}
Surely there must be something simple to catch/handle a session timeout or lost conversation?
I am using GlassFish 3.1.1 all updated...
the session timeout is intentional but I want to redirect back to the login/landing...
Any help/suggestions greatly appreciated..
Best Regards,
JOHN.
