  • Execute method on startup in spring

    - by Javi
    Hello, Is there any Spring 3 feature to execute some methods when the application starts for the first time? I know that I can do the trick of setting a method with @Scheduled annotation and it executes just after the startup, but then it will execute periodically. Thanks.

  • How can I cancel Drag and Drop operation in Java/Swing programmatically?

    - by AlexV
    I am just wondering if it's possible to I cancel "Drag and Drop" operation in Java/Swing programmatically? So the effect would be similar to if the user pressed the "ESC" key? I was expecting DragSourceDragEvent or DragSourceContext to have a cancelDrag() method, similar to DropTargetDragEvent which has acceptDrag() and rejectDrag() methods (both of which does not do what I want). I am missing something?

  • Can't ping self

    - by Paddy
    I have a wireless internet connection setup on my Mac. (v10.5.6) Am connected to the internet and everything is running smoothly. I recently discovered a quirky behaviour while setting up apache web server. When i typed in my dynamic ip (http://117.254.149.11/) in the webbrowser to visit my site pages it just timed out. In terminal i tried pinging localhost and it worked. $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.044 ms But if i pinged my ip it would just time out. $ ping 117.254.149.11 PING 117.254.149.11 (117.254.149.11): 56 data bytes ^C --- 117.254.149.11 ping statistics --- 10 packets transmitted, 0 packets received, 100% packet loss Pinging any other site works though. I am completely stumped. Any help would be greatly appreciated.

  • JavaScript method to write to Microsoft Visual Web Developer Debugger?

    - by Josh
    I generally test my web apps with Firefox and use Firebug. I love Firebug. But when I'm testing JavaScript code in IE I use the debugger in Microsoft's Visual Web Developer 2008 Express Edition. I would love to have an equivalent to Firebug's console.log methods which would allow me to log messages to Visual Web Developer. Any way to log messages to the error list/messages list/output pane using JavaScript?

  • How to catch an exception and email information about it in liferay portlet

    - by heikkim
    I have a custom portlet made for liferay and sometimes it throws an exception. Why it throws exceptions is irrelevant. How to catch exceptions thrown by portlet handler methods in order to email information about them? I know I could do try catching on every handler method but it would be a much more elegant and cleaner solution to catch the exception on a higher level and just email some information about the error. I'm using Spring Portlet MVC, so i got all spring-related niceties at hand.

  • Does Hibernate always need a setter when there is a getter?

    - by Marcus
    We have some Hibernate getter methods annotated with both @Column and @Basic. We get an exception if we don't have the corresponding setter. Why is this? In our case we are deriving the value returned from the getter (to get stored in the DB) and the setter has no functional purpose. So we just have an empty method to get around the error condition..

  • Using Javascript, How do I bring an already existing open window to the front on top of other window

    - by user268249
    The question was fairly descriptive but I'll describe it further. Basically, I have Window1, clicking a button link opens window2. Clicking a button in window2 opens window3, clicking a button in window3 should bring window2 back to the front of the screen on top of window2. I'm not sure how this is exactly done, however I have used and played around with focus(), opener and other various methods and I cannot seem to get it to work properly. Thanks for any help in advance!

  • dhclient and dhcpcd the real difference

    - by rubixibuc
    I can't figure out the difference from just the man pages. I can see what is a daemon and one is a client, but what does that mean practically when using the commands? Also what is the difference between the client and daemon in this case, not just the terms (client and daemon) but functionally wise? EDIT: How are the tasks divided, if the client updates the information on the client, what is the purpose of the daemon. I'm talking about the client daemon in this case dhcpcd not dhcpd. Both come installed by default with some versions of Linux and seem to share the duties of the dhcp client. NAME dhcpcd - DHCP client daemon Name dhclient - Dynamic Host Configuration Protocol Client
