Problem with Session Management #41

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What version of the product are you using?
1.2.0

Please provide any additional information below.

The server push is implemented within an application with an embedded session 
management mechanism. As can be seen in the logs provided below,  although the 
sessionId is generated prior to the addition of the listener, an 
NoSessionAvailableException is thrown:

GoogleCodeExporter commented 9 years ago 
I discovered that this exception occurs when the max. waiting time is greater 
than the session max. inactive interval.

Hi, does it mean that this issue can be closed because it was a configuration 
problem?

Yes, you can close it - I do not consider the problem encountered a bug.

Hi,

Same here: on version 1.2 max. inactive interval is 15 min and  max. waiting is 
20 sec. Still getting the same exception. But it's intermittent. It's on Apache 
+ Tomcat workers configuration.

no session available! Maybe no session was generated explicitly by the

Hi 
From time to time, I have the same problem 
de.novanic.eventservice.service.exception.NoSessionAvailableException: There is 
no session available! Maybe no session was generated explicitly by the 
connection id generator
I am using glassfish and ListeEventListener V1.2
Changing rhe session-timeout in web-xml has no effect on this problem.
Thanks for your help

This is not invalid.
