java - Problem logging out user on chat applet -

-

i wish users of java chat applet automatically logged out when closing browser window.

i use following:

public void destroy() {     sendlogoutmessage(); }

however works 3/4 of time (probably due network delays).

the chat applet pings server , logs them out after 90 seconds (this allows them reconnect due internet problems) - removed eventually, way better catch close event.

i think code not work in 100% cases because called in destroy method not wait , closes including network connections being opened. so, if network slow applet output streams killed before sends logout message server.

if theory correct can check it.

  • try see whether logout command in server logs (in case of failure). believe find command did not arrive.
  • open java console on client side. ioexception or socketexception. hope examining of exception may give idea how improve solution.

additionally i'd suggest following.

  1. add servlet session listener on server side , logout automatically when session expired.
  2. decrease time-to-live of http session reasonable number. default value jboss 20 minutes, make 1 minute.
  3. implement keep-alive mechanims applet. may simple. perform http every 30 seconds special url nothing. keep session alive.

this solution should addition existing solution works 3/4 of times.

i hope helps. luck.

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
