This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
hi, I have an application, which deals with the client Server implementation. I use to send request to UDP server and in udp server class ,JOptionPane.showmessageDialog(null,"" ) is implemented in catch block, when ever there is delay in retrieval of response from server side. Since udp client socket waits for particular amount of time. I there is delay in response,or connection is not establish, jOptionPane gets pop.
But problem is that many times,when this jOptionPane pop come gui hangs.
Please do the favour by giving any suggestion. regards, Sachindra
Are you doing any computationally intensive task on the event-dispatcher thread?
In Swing, lengthy initialization tasks (e.g. I/O bound and computationally expensive tasks), should not occur in the event-dispatching thread because this will hold up the dispatcher thread. If you need to create a new thread for example, to handle a job that�s computationally expensive or I/O bound then you can use the thread utility classes such as SwingWorker or Timer without locking up the event-dispatching thread.
�SwingWorker � creates a background thread to execute time consuming operations. �Timer � creates a thread that executes at certain intervals.
