Re: persistance cache

2015-06-24 Thread Kaouthar Ghorbel
hello, I think it is a cache problem , because when I restart tomcat
the resulting list is correct, the problem lies only  for this method.
i use tomcat 8.0.2

 But is this related to Tomcat somehow ?
 If yes, could you explain how, and provide some versions of the software
 used ?

 1.) Add %D or %T to your access log format.  That will log info about
 how long the request took to process.

 %D - Time taken to process the request, in millis
 %T - Time taken to process the request, in seconds

 http://tomcat.apache.org/tomcat-8.0-doc/config/valve.html#Access_Log_Valve

 2.) This valve can also help.  It'll dump a stack trace when a request
 takes longer than the configure threshold.
