appeal of XHTML to servlet return do not answer, do not call servlet

I xhtml in a web app using a servlet, but the answer of the servlet does not appear. The original xhtml displays once you press the submit button. I tried different alternatives for the servlet response, but I get the same result every time. I added logging to the servlet, but it seems that the servlet is not called at all.

Y at - it a special format to send a form to a servlet of xhtml? Any ideas what could be the problem?

Call it a guess, you're not the first to fall into the trap of the nested :) form Its too easy to simply slap a high h:form somewhere near the top of the tree and forget it.

For the future: remember that the browser is actually doing the work when you submit a form. If something goes wrong, it appears in the HTML source as you can see by using the function "view page source" from the browser. It pays to know HTML and especially the limits if you want to understand such things by yourself. When you locate the faulty HTML code, it is usually not so hard more to trace what is bad in the JSF source.

  • Firefox on Android sync returns "could not sign."

    I have Firefox for Android beta v39 and Firefox for Android v38 installed on my phone (Lollipop 5.0.2) and little matter which of these browsers, I try, when I have connection for synchronization, it gives the message "Unable to connect"... I have installed on my linux desktop v38 and it works with the same credentials. I tried to reset the password, and it also does not help, because the problem is always the same... Desktop Sync works and it does not work on Android. Any suggestions?

    I understand that Firefox for Android returns: "could not sign" I am happy to help you. Let's try a new connection by removing the account first.

    1. First unplug the account settings under 'Accounts' Android
    2. After listening to remove, open a new window in Firefox
    3. Go to https://accounts.firefox.com
    4. Connect once more and make sure that in your account settings, that data usage is set to auto sync.

    For troubleshooting, you have any content blockers or filters/proxies on your device?

  • Web service JSON data do not return does not

    I created an application with a test sample local (active forlder) json file called "contacts.json" as below, just to test if I have any return data. The data returned in a listview without problem.

    [{ "id":1, "firstname": "Mike", "lastname": "Chepesky", "title": "Sr. Editor",
      "image": "images/data/mike_chepesky.png", "active": true, "gender": "m" },
    { "id":2, "firstname": "Westlee", "lastname": "Barichak", "title": "Talent Scout",
      "image": "images/data/westlee_barichak.png", "active": true, "gender": "m" }]
    

    I then changed the source for 'http://... '. "a link is valid and I checked, and it returns the data in a classic web browser (firefox). But he won't be in my application.

    What I noticed, is that the difference between the local json file and the return of web service, the web service does not return the square brackets "[...]" the json... I suspect that maybe that's the problem? If so, how do I manipulate the data source in my application to incorporate media? Is the returned data (without brackets) real...

    {"status":"successful","current_version":"1.1.1","latest_version":"1.2.0.0","details":"1. Item A 2. Item B 3. Item C","type":"Force update"}
    

    Thank you.

    If I'm not wrong, your local file json contains an array of objects, and that you load from your server contains a single object.
    If so, you can not call insertList (data), use insert (data)

  • AppModuleImpl methods of the class returns the custom class types, not called.

    Methods of the class AppModuleImpl custom types of class, not called when you access through back links.

    Any help will be appreciated.

    How to retrieve variable 'bindings '?

    Where is the OI_testBean.goInstanceName_methodCallNew () method called?

    If this method is called from the method call activity, you create pageDef in his name and add getInstanceNameO

  • Extended method of field paint will not called

    I would go to a field and would like to paint something there.

    By extending the field I must apply setLayout (int x, int y) wcich get is called successfully.

    Thing strange number one: x is 360 (that's fine because I have it returned by getPreferredWitdh), there is

    1073741803 which is more hell? In getPreferredHeight I returned 480...

    Second, my method of painting is not called at all! See code below.

    You forgot to call your layout() setExtent() while defining the scope of the field is the main object of the layout () - to tell the parent Manager how much space you wish to occupy. Without putting your width and height are (0, 0), which explains why your parent Manager never calls object of your field.

    The fact that you get almost unlimited height in your layout() is also easy to explain: you probably use screen that has default VERTICAL_SCROLL.  And managers who have VERTICAL_SCROLL allocates Integer.MAX_VALUE > 1 pixel at the start for their children.  Your LabelField consumed 14 of this value (using setExtent (textWidth, 14), of course) and then screen offered the rest of your domain.

    Also note that getPreferredHeight() and getPreferredWidth() are ignored by the vast majority of managers and fields.

    I was checking to see if the deconstructor was called, but it doesn't seem to be. So I think it might be the QTimer not cleaned but I don't know how I get it to call on family members since I thought that once I signed with qml my QObject class would be deconstructed with other resources in a certain order.

    Thanks in advance for any help

    Do not call bps_get_event from an application of stunts that you might fly the main event loop events.  Rather implement AbstractBpsEventHandler to the BPS events delivered on the thread of your event.

    You call system.exit() in the Builder before entering the EventDispatcher. I'm guessing that you add the menu item, but leave the application, and when the menu item is called it is more a reference to the context of the application and decides not to continue. The menu item will not remove itself when the application closes.

  • Bean method &lt; a4j:commandButton &gt; backend is not called on the click event.

    I use code below. It seems back end bean method is not called when I click on the CommandButton. I think it has something to with the rendering.

    Everything works perfectly. But when I click on the command button "#{testPropertyRefreshHelper.updatePropertyFileContentInRemoteServer}" backing bean method is not called. Other components are working properly.

    try what it says the article linked: do your session bean scope.

    NOTE: when working with Ajax I tend to do the session bean to support extended to have fewer problems with partial and such updates. If you are using JSF 2.0, you could do it view extended to get the same result.

  • Windows call you if you have not called?

    I got a strange call today. The guy calling said it was Windows support and that I had something encrypted in my computer that sent many emails and it would destroy my hard drive if I don't go to my computer and let it guide me through the connection and it allow to correct the problem. What's up with that? I have NOT called Windows with any problem and have had my PC scanned with 3 anti virus and anti malware programs and does not appear in case of problems. I went in my history of scanning and it shows that someone tried to get into my computer but have been blocked several times. Would it be legitimate? The number he called from is 201-338-6150 located in Dumont, NJ (fixed) listed in teleport communications group. Someone advised me that it is. Thank you
