  • Bean validation VS JSF validation

    - by henloke
    When facing the problem of validating a property in a JSF2 application there are two main approaches. Defining the validation on the ManagedBean using an Annotation @ManagedBean public class MyBean { @Size(max=8) private String s; // Getters setters and other stuff. } or declaring it on the jsf page: <h:inputText value="#{myBean.s}"> <f:validateLength maximum="8"/> </h:inputText> It happens that I can't decide for none of them. The first one is nice because it removes some code from the jsf pages (which is always good since those pages are not eye friendly by definition) but makes harder to see 'at a glance' what's going on with the page when checking the jsf file. Which one do you think is clearer? Nicer? Better?

  • XP Mode (Windows Virtual PC for Windows 7) no longer requires hardware virtualisation - hurrah !

    - by Liam Westley
    Windows Virtual PC (aka XP Mode) When XP Mode was released, it insisted on hardware virtualisation being present on your CPU and enabled in the BIOS.  Given that Windows Virtual PC was based on an improved Virtual PC 2007, which provided hardware virtualisation as a user selectable option, I did wonder why on earth Microsoft thought this was a good idea.  Not only do many people not have a CPU with hardware virtualisation support, some manufacturers don't provide a BIOS option to enable this setting, especially on laptops - yes Sony, Toshiba and Acer, I'm looking at you. Dumb and dumber This issue became a double whammy; not only was Microsoft a bit dumb on not supporting Windows Virtual PC without hardware virtualisation, your hardware manufacturer was also dumb in not supporting the option in the BIOS. Microsoft update to Windows Virtual PC Belatedly, Microsoft has seen the problem with this hardware virtualisation requirement and has now released a new version of Windows Virtual PC that works without hardware virtualisation.  This is really good news for those with older (or limited) CPUs and rubbish BIOS firmware. You can details of how to download the new versions of XP Mode here, http://blogs.msdn.com/virtual_pc_guy/archive/2010/03/18/windows-virtual-pc-no-hardware-virtualization-update-now-available-for-download.aspx And there is also an explanation of why the hardware virtualisation requirement was in place for previous releases, http://blogs.msdn.com/virtual_pc_guy/archive/2010/03/18/windows-virtual-pc-now-without-the-need-for-hardware-virtualization.aspx

  • Thanks to NxtGenUG Manchester - Hyper-V for Developers presentation now available for download

    - by Liam Westley
    Thanks to Steve and Andy at NxtGenUG Manchester for making me very welcome and for the guys who didn't head down the pub for a Guinness for St Patrick's Day and came to NxtGen instead.  I hope you all got something from the presentation, if not technical insights, at least a can of Guinness of Tunnocks caramel wafer as swag. As promised here is the presentation in both PowerPoint and Adobe PDF format (with speaker notes), http://www.tigernews.co.uk/blog-twickers/nxtgenugmanc/hyperv4devs-ppt.zip http://www.tigernews.co.uk/blog-twickers/nxtgenugmanc/hyperv4devs-pdf.zip Since I gave the presentation Microsoft has released XP Mode (Windows Virtual PC for use under Windows 7) without the requirement for hardware virtualisation. Read more about that here, http://blogs.msdn.com/Virtual_PC_Guy/ For anyone who has seen this presentation at other user groups, there is a new section at the end of the presentation dealing with the various networking configurations under Hyper-V; not connected, private network, internal network and external network.  This includes details of what these mean, and a Venn diagram to aid understanding of the implications.

  • It is possible to use the Exchange 2010 web client with an Exchange 2007 mail server?

    - by michielvoo
    We are evaluating our options to upgrade our Windows SBS 2003 server. We are considering Windows SBS 2008, which comes with Exchange 2007 and an extra Windows Server 2008 Standard license. If we also bought Exchange 2010, could we install it on the Windows Server 2008 Standard machine and use the web client in combination with the Exchange 2007 server (that would be hosting the mailboxes)? Is that a supported server role for Exchange 2010? I remember reading about so called front-end server configurations, but I have no experience with that. Thanks!

  • Why jquery have problem with onbeforeprint event?

    - by Cesar Lopez
    Hi all, I have the following function. $(function() { $(".sectionHeader:gt(0)").click(function() { $(this).next(".fieldset").slideToggle("fast"); }); $("img[alt='minimize']").click(function(e) { $(this).closest("table").next(".fieldset").slideUp("fast"); e.stopPropagation(); return false; }); $("img[alt='maximize']").click(function(e) { $(this).closest("table").next(".fieldset").slideDown("fast"); e.stopPropagation(); return false; }); }); <script type="text/javascript"> window.onbeforeprint = expandAll; function expandAll(){ $(".fieldset:gt(0)").slideDown("fast"); } </script> For this html <table class="sectionHeader" ><tr ><td>Heading 1</td></tr></table> <div style="display:none;" class="fieldset">Content 1</div> <table class="sectionHeader" ><tr ><td>Heading 2</td></tr></table> <div style="display:none;" class="fieldset">Content 2</div> I have several div class="fieldset" over the page, but when I do print preview or print, I can see all divs sliding down before opening the print preview or printing but on the actual print preview or print out they are all collapse. I would appreciate if anyone comes with a solution for this. Anyone have any idea why is this or how to fix it? Thanks. PS:Using a does not work either ( I assume because jquery using toggle) and its not the kind of question I am looking for.

  • Output asp.net masterpage webform to html email

    - by Steve McCall
    Hi I'm having a bit of a nightmare here! I'mv trying output a webform to html using page.rendercontrol and htmltextwriter but it is resulting in a blank email. Code: StringBuilder sb = new StringBuilder(); StringWriter sw = new StringWriter(sb); HtmlTextWriter htmlTW = new HtmlTextWriter(sw); page.RenderControl(htmlTW); String content = sb.ToString(); MailMessage mail = new MailMessage(); mail.From = new MailAddress("[email protected]"); mail.To.Add("[email protected]"); mail.IsBodyHtml = true; mail.Subject = "Test"; mail.Body = content; SmtpClient smtp = new SmtpClient("1111"); smtp.Send(mail); Response.Write("Message Sent"); I also tried it by rendering a single textbox and got and error saying It needed to be within form tags (which are on the masterpage). I tried this fix: http://forums.asp.net/p/1016960/1368933.aspx#1368933 and added: public override void VerifyRenderingInServerForm(Control control) { return; } But now the errror I get is: VerifyRenderingInServerForm(Control)': no suitable method found to override Does anyone have a fix for this? I'm tearing my hair out!! Thanks, Steve

  • SSIS to copy data from one table to another, where not in destination table

    - by alex
    I'm in the process of creating an SSIS package on a server (server1) that looks at the data in a sql db on another site (server2) and copies relevant rows across. The SQL statement required is: SELECT * FROM server2.ordersTable WHERE OrderID Not In (SELECT OrderID FROM server1.ordersTable This selects data from server1 which isn't in the table on server2 (based on order id) I then need to insert the result into a table on server1 How would I approach this? What components do I need etc...?

  • Using Option all over the place feels a bit awkward. Am I doing something wrong?

    - by Geo
    As a result of articles I read about the Option class which helps you avoid NullPointerException's, I started to use it all over the place. Imagine something like this: var file:Option[File] = None and later when I use it: val actualFile = file.getOrElse(new File("nonexisting")) if(actualFile.getName.equals("nonexisting")) { // instead of null checking } else { // value of file was good } Doing stuff like this doesn't feel all that "right" to me. I also noticed that .get has become deprecated. . Is this sort of stuff what you guys are doing with Option's too, or am I going the wrong way?

  • Is Zabbix the right tool for me?

    - by hortitude
    I just want to monitor a small handful of servers (less than 10). From reading various places it sounds like the top leading contenders (for open source at least) are: nagios munin zabbix From what I have read a lot of people tend to use munin and nagios together -- munin for history and graphs, and nagios for alerting. On the other hand it sounds like Zabbix is a more complete solution and easier to configure than either of the other two. So I was thinking of going that route. My thoughts right now are: What are the general disadvantages of Zabbix? Does Zabbix have a small footprint on boxes it is monitoring? Do I really need to setup an entire other server for it? I currently have a server that is under very light load -- can I dual purpose it?

  • Is there a feature in Nagios that allows Memory between checks?

    - by Kyle Brandt
    There are various instances where there are values I want to monitor with Nagios, and I don't care as much about the value itself, but rather how it compares to the previous value. For instance, I wrote one to check the fail counters in OpenVZ. In this case, I didn't care about the value that much, but rather I cared if the value increased. Another example might be switch ports, I would be most interested to get alerted about the change of state of a port (Although perhaps a trap would be better for this one). For my OpenVZ script, I used a temp file, but I am wondering if there is a better way? Maybe Nagios has some variables that plugins (check scripts) can access that are persistent across checks?

  • A problem about in_array

    - by SpawnCxy
    Hi all, I have got a strange problem about in_array recently which I cannot understand. e.g. $a = array('a','b','c'); $b = array(1,2,3); if (in_array(0,$a)) { echo "a bingo!\n"; } else { echo "a miss!\n"; } if (in_array(0,$b)) { echo "b bingo!\n"; } else { echo "b miss!\n"; } I ran it on my lamp,and got a bingo! b miss! I read the manual and set the third parament $strict as true,then it worked as expected.But does that mean I always need to set the strict parament as true when using in_array?Suggestions would be appreciated. Regards

  • Project based on J2EE

    - by zakovyrya
    Would you start J2EE project nowadays if you have other alternatives? UPDATE: I think little clarification is needed: Is it worth investing in J2EE if practically everything it claims to offer can be achieved by using other technologies? To be honest, J2EE scares me by its monstrosity and I foresee substantial maintenance and/or evolution costs.

  • Can't send key to window with SendMessage

    - by user297313
    I'm writing a C program under Windows that should send an ENTER key to a dialog box to close it automatically. I retrieve the handle to the top level window I'm interested in (by means of EnumDesktopWindows()) and then try to send an ENTER key using SendMessage (note also that closing the window by sending WM_CLOSE works fine). None of the following works: SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 0 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); and so on... As a possibly simpler scenario, I also tried to send an ascii key to, say, notepad. How is this supposed to work? Thanks in advance
