Forms empty when Redirected

I'm having trouble with a login page i've created. When a user logins in, they enter their login and password in the forms, then they submit it. It then goes to another page which accesses the database to verify that the user exists and the password is correct. If it's incorrect the page calls the login page back with:
RequestDispatcher rd = request.getRequestDispatcher("login");
rd.forward(request,response); // i've included that to return a value back to the login page letting them know that the login wasn't valid
But I want the username to stay filled out in the form when it goes back to the login page, but the username and password fields are both empty.

when u submit the form from the login.jsp, u pass the login name as a hidden variable in the form of :
<input type=hidden name=LoginName value=""> etc etc.
In this case the variable "LoginName" gets attached to the request.
in case u find the it invalid in the database page and you do a rd.forward(), the same request gets sent to the login page and hence u can access the name in this fashion
String login = request.getAttribute("LoginName");
and put an html statement of this kind
<input type=hidden name=LoginName value="<%=login%>">
I hope you get it.

  • Saved pdf forms empty in Reader, filled in Preview

    Today I was informed that pdf forms I've filled and saved/emailed with Preview are empty when viewed with Reader 9 (Win or Mac). If the recipient sends the form back to me, Preview shows the form just as I've filled it. Reader 9 on my MBP also shows the form empty, emailed or not.
    Seems to me, that Snow Leopards Preview has some bugs. I hope these are redemied in 10.6.2.

    HI,
    Try deleting this file.
    com.apple.Preview.plist
    ~/Library/Preferences.
    Move that file to the Trash and restart your Mac.
    If that did't help, try deleting this file as well.

  • Click close button in infopath form shuld be redirect to site page not a list by default

    Hi
    I am custmizing a list in infopath
    i created a view created by user and
    i created a site page and assigned a created by user view to a webpart on this page
    here i need when this list opens in edit mode , when i click close button this form shuld be redirect to site page
    now its rediricting to list>all items
    all items is default view for this list
    adil

    Hi adil,
    According to your description, my understanding is that you wanted the redirect to another page once InfoPath form had been closed.
    You can add a Content Edit web part above the InfoPath form web part with the following code:
    $(document).ready(function(){
    if($('#DialogFinalMessage').children().length>0)
    window.location.href = "<Desired destination page URL>";
    For more information:

  • TOA_DARA fields empty when Archiving SD invoices

    Hi gurus,
    We have a problem when archiving SD invoices. In some cases, when archiving, are ocurring errors that shows on SM58.
    The error is always:
    <<
    ARCHIV_CREATE_TABLE            SAP_AL_OUT                       21.06.2011 18:22:23 SAP ArchiveLink: tipo objeto no asign.a ningún arc hivo (Customizing)
    >>
    And it's generated when saving the invoice from transaction VF01
    We thought the problem could be that the object type was not maintained on the system but that's not the case, the problem is that the type is coming empty.
    Watching inside the error, these fields are empty:
    AR_OBJECT (should be SDINVOICE)
    SAP_OBJECT (should be VBRK)
    OBJECT_ID (should have the invoice number)
    We were thinking about this TOA_DARA structure determination, but we could not see where it's been generating.
    Do you know how is it possible that "sometimes" these fields go empty when processing sd invoices messages?
    Thanks in advance

    Hi Sudheer,
    In my case, I saved the TOA_DARA params into an aux var just before calling the OPEN_FORM. Then, I checked the params before calling the function which archives.
    clear toa_dara_aux.
    toa_dara_aux = toa_dara.
    CALL FUNCTION 'OPEN FORM'...
    if toa_dara is initial.
         toa_dara = toa_dara_aux.
    endif.
    CALL FUNCTION 'CONVERT_OTF_AND_ARCHIVE'
         EXPORTING
              arc_p = arc_params
              arc_i = toa_dara
              format = 'PDF'
         TABLES
              otf = otf.

  • Losing AM State when redirect="true" on struts forward

    Works fine on embedded server.
    Deploy to 10.1.2 OC4J stand-alone. Viola AM and session lost when redirect="true" on a forward....any ideas?

    Thanks, silk.
    That may be a possibility. I'm not sure I want the
    client to have to make a second request,Isn't that what you mentioned in the OP ? ... if the
    clients hit
    your page, but you really want them to go somewhere
    else,
    you have to do it client-side ..
    I thought that was the difference between forward and
    redirect: forwarding is handled server side, and
    redirecting is a response back to the client telling
    him to go somewhere else. Ggainey said he thought you
    could only forward locally. Are you confirming that
    that's the case?what i was talking about was that even forwarding locally is done client
    side; http-headers, no? i was suggesting that the idea of using a HttpConnection,
    obviously, would not make that client go there, the server would ...
    and I'd
    rather have just the XML by itself, without itbeing
    something's value.Not sure what you mean here, if you are 'posting'it,
    it
    has to be a value...I don't think so. Yes, you're right, i don't know what i was thinking when i wrote that.
    If the only way to avoid a huge nasty roll-my-own is
    to send the XML as a value, then I guess I can do it.Perhaps you could look into the way files are uploaded via html;
    and hook your xml up to that instead of as a plain-old form value...?
    depending on how large your xml-file is this is probably the most
    appropriate way to go ...
    This raises the next question: What do I have to do to
    the XML to make it behave nicely as the RHS of value=?htmlEncode it; basically the double quotes just need to be " or whatever the
    appropriate html code is. (note it will need to be reversed on the other side).
    (of course, if you are going the file route; it will be in base64 form.)

  • How to define target window when redirecting within frames using servlet?

    Your servlet (or JSP) can't decide where it is going to be displayed. The browser has already decided that when it makes the request to your servlet.

  • Can 3 vertical Radio Buttons span 3 rows in a table? AND how to make form highlight when radio butto

    I am trying to add 3 grouped vertical radio buttons where one is on each line of a 3 row table. When I group the 3 buttons it squeezes them into one row, is there a way I can have them grouped and one in each.
    Also, I would like to know how to make part of the form highlight when one of the 3 buttons is selected

    Hi,
    If I am not wrong, a table cell can hold only one component or none. In order to place the radio group to different positions vertically, you can use subforms instead of table.

  • Data node mapped to  Adobe Form empty - Web Dynpro ABAP

    Hi,
    I've created a web dynpro component in ABAP. One of the view contains an interactive Adobe form.
    Form properties : Data source and pdf source are mapped
    Enabled checked
    Submit action mapped to a method. This method reads the node mapped to the form.
    Form Layout: Used ZCI Layout and Inserted web dynpro script (XML interface)
    Dragged attributes from data view to create text fields.
    Submit button used from Web dynpro native group
    I could not read data from the form.
    When I submit the form, data is not captured in the context.
    I have used the same context for view and could save the data from the view. But from the adobe form, I cannot read the data.
    Is there anything I missed. I have been on this since 2 days with no solution. I dont see any mistake but the form doesnt work.

    A word document was emailed to me.  I can open the document without a problem on my iPad 2.   Is there a way for me to type on the document.... to fill out the form?  When I click the fields, the virtual keyboard does not appear.

    If you want to edit a word document then you will need an app on your iPad that supports word so that you can copy them to it via 'open in' e.g. Apple's Pages app or a third-party app such as Documents To Go or QuickOffice HD

    I have my photos in  iPhoto but my iPhoto library is empty.When clicked message reads could not be opened image capture cannot open files in the photo library format. How do I get my photos back into my library?

    When what is clicked?
    There are 9 different versions of iPhoto and they run on 9 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
    - What version of iPhoto.
    - What version of the Operating System.
    - Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
    - History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
    - What steps have you tried already to solve the issue.
    - Anything unusual about your set up? Or how you use iPhoto?
    Anything else you can think of that might help someone understand the problem you have.

    My CD reader says all my CDs are empty when I know they are not. Is my reader down or is there a setting that is off?

    Yes. you should keep your media in iTunes, and indeed you should also keep a backup of your library as well. if you have the device set up for manual management then the content would remain on it when deleted from the library, but you would have no way to restore the device if there was a problem.

  • I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud

    I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud option in Acrobat. Kindly help me to sortout this problems?

    So I tried generating the same PDFs on two other computers that have Acrobat 9 Pro.  Results were reproduced.  The verdict is:
    - complex PDF files (that is, containing cross-references, tables of contents, and bookmarks) generated by Acrobat 9.x Pro are roughly 2-5x larger than the identical file generated with Acrobat 8.x Pro.
    - different PDF conversion settings make a negligable difference (less than 10% rather than 70-80%).
    - using the "Reduce File Size" or "Optimize PDF" option cuts the file size roughly in half, almost always resulting in a "image downsampling mask" warning message, which requires acknowledgement (that is a problem for batch processing or automation).
    - adding an Acrobat watermark to the file cuts the file size roughly in half.
    - just using Save As to another filename has no effect on file size.
    - generating the PDF in Acrobat 9 with links but no PDF bookmarks still results in the inflated file size.
    - generating the PDF in Acrobat 9 without any links or bookmarks results in approximately the same file size as the Acrobat 8 PDF with full links and bookmarks.
    It appears that Acrobat 9's manner of adding links is what's bloating  the files, and in my case it's probably not related to images or image resolution/print quality.  It's a shame, because Acrobat 9 seems to have made some  improvements to the Review Tracker interface, and a few other bells and  whistles which I haven't really gotten around to exporing yet.  But  unless I find a way to keep my links and the PDF file sizes comparable to what I was  getting with Acrobat 8 Pro, it looks like I'm going to stay with Acrobat 8.

  • Unable to use HTTPS proxy when redirecting HTTP/HTTPS via NAT

    I'm trying to get the WSA to work when redirecting HTTP and HTTPS traffic along the lines of the following:
    object network WSA-HOST
          host 10.0.210.2
    object network obj-10.0.1.0 subnet 10.0.1.0 255.255.255.0
    object service ORIG-HTTP-PORT
          service tcp destination eq www
    object service WSA-HTTP-DEST-PORT
          service tcp destination eq 8080
    object service ORIG-HTTPS-PORT
          service tcp destination eq https
    object service WSA-HTTPS-DEST-PORT
          service tcp destination eq https  << also tried 8080 etc.
    nat (inside,outside) source dynamic obj-10.0.1.0 interface destination static obj_any WSA-HOST service ORIG-HTTP-PORT WSA-HTTP-DEST-PORT
    nat (inside,outside) source dynamic obj-10.0.1.0 interface destination static obj_any WSA-PROXY-HOST service ORIG-HTTPS-PORT WSA-HTTPS-DEST-PORT
    This works just fine for HTTP, but with HTTPS I get the following response from the Ironport WSA:
    Based on your corporate access policies, access to this web site ( https://www.rbsdigital.com/ ) has been blocked.

    If anyone has any idea why the WSA simply denies the connection instead of proxying it then I'd be grateful.
    The WSA and the decryption policies work fine in explisit mode.
    Thanks in advance!

    The policy doesn't require authentication. Now here are two tests I did, seconds apart, from the same client on 10.0.4.140:
    First one is where I use NAT as shown above:
    1329757052.027 118 10.0.4.140 NONE_SSL/200 0 TCP_CONNECT 10.0.210.2:443 - NONE/- - OTHER-NONE-NONE-NONE-NONE-NONE-NONE <-,-,"-","-",-,-,-,"-","-",-,-,-,"-","-",-,"-","-",-,-,-,-,"-","-","-","-","-","-",0.00,0,[Local],"-","-"> -

    Second test case is when I reconfigured the browser to explisitely use the WSA as a proxy on port 8080:
