Must have a valid X Window Session!?!?

Hi!
I recently discovered that if you're about to use the BufferedImage-functionality in the standard Java SDK (1.4.1) then you must have a running X-Window session which the SUN-classes connects to when your create your BufferedImage.
Why is that?
I'm running Java on our Linux-server and does not want to have an unecessary X-Window session running just to be able to create BufferedImages in memory.
Have anyone else discovered this?
/Charlie

There are pseudo-X-servers to provide the minimal facilties to a java awt client.

  • To download shared content, your family must have a valid payment method

    I'm trying to share movies bought on my account with my son and keep receiving the message "to download shared content, your family must have a valid payment method". I already have a credit card linked to my account. Help?

    Hi Mel3b,
    I'm sorry to hear you are having these issues with Family Sharing. If you are getting the "valid payment" alert message when you alreadyt have a credit card on file, you may want to try re-entering the card details on the account, even if you know they are currently correct.

  • To download shared content, your family must have a valid payment plan

    Get this error message when someone tries download content after being added to the shared family plan.

    My daughter had the same error. We got this working by going to the book on her phone, proceeding to download/purchase the book. It then informed us that someone else in the family had purchased this previously. We went ahead and said download and it worked. 

  • I must have made some change to my Pages preferences.

    I am working on a book using Pages (iWork 09).  I have had no problem with opening two Pages documents I have created and have then both display on the desktop.  I readjust their sizes and they sit there side by side.  I don't remember making any changes to any preferences.  Just recently, whenever I open the first document and it pops onto the desktop.  Great.  Now, when I go to open the second document that I want to sit right beside the first document, the second document opens okay but the first document that I opened "zips" off the desktop.  What have I done wrong?  I know I must have made some inadvertent change because I have been doing this (putting both documents side by side ) for months.

  • Session State Protection - Arguments must have Checksum - Help Required

    Hi everyone,
    I am using apex 4.0 and have set:
    Session State Protection = True
    Page Access Protection = Arguments must have checksum
    Application Item Protection = Cecksum required - Session Level
    Page Data Entry Item Protection = Cecksum required - Session Level
    Page Display-Only Item Protection = Cecksum required - Session Level
    On pages which contain a Interactive report the calls to other pages to update and or delete a record passing the PK of the record work OK.
    I have set these as follows:
    In the Interactive report LInk Colomn --> Link Attribute = onclick="new top.Ext.apex.PopupWindow( { url: this.href, title: 'Edit Classification Details', width: 530, height: 500, listeners: {'success': gReport.search} } ).show(); return false;"
    Target = Page in this Application
    Page = 302Item = P302_IDCLASS
    Value = #IDCLASS#
    Page Checksum = - User Default -
    The problem is on the "Create new record" button which is located on the Interactive report page. I have defined the button as:
    Button Attributes = onclick="new top.Ext.apex.PopupWindow({ url:'f?p=&APP_ID.:302:&APP_SESSION.::NO:302::::', title: 'Create New Classification', width: 530, height: 500, listeners: {'success': gReport.search} }).show(); return false;"
    Action when button click = Redirect to Page in this Application
    Page = 302
    Clear Cache = 302
    When I click the button I get the following message:
    Session state protection violation: This may be caused by manual alteration of a URL containing a checksum or by using a link with an incorrect or missing checksum. If you are unsure what caused this error, please contact the application administrator for assistance.
    If I change the Button attributes to be:
    onclick="new top.Ext.apex.PopupWindow({ url:'f?p=&APP_ID.:302:&APP_SESSION.::NO:::::', title: 'Create New Classification', width: 530, height: 500, listeners: {'success': gReport.search} }).show(); return false;"
    It works OK, bu the page items are not clear.
    Could someone please explaing to me what am I doing wrong so I understand my mistake ?
    Thank you
    Daniel

    Here's an interesting situation. I have been having great results with the prepare_url function, until I needed to pass a column value from a report into a popup.
    Originally, in the Column Link --> URL in the Report Attributes I had this. This worked great when there was no session state protection enabled.
    javascript:popUp('f?p=&APP_ID.:17:&SESSION.::&DEBUG.:17:P17_EVENT_LOG_ID:#EVENT_LOG_ID#','450','375');When I enabled session state protection and changed the URL link to this
    javascript:popUp('&VW_EVENT_LOG.','450','375');and then created an application item and computation in order to pass a checksum along
    APEX_UTIL.PREPARE_URL (
      p_url => 'f?p=&APP_ID.:17:&SESSION.::&DEBUG.:17:P17_EVENT_LOG_ID:#EVENT_LOG_ID#',
      p_checksum_type => 3
    );the checksum seems to get passed fine, but the column value for the EVENT_LOG_ID is being concatenated to the end of the checksum instead of being passed as the value for P17_EVENT_LOG_ID. I also noticed that the clear cache page (17) looks like it is also being attached to the beginning of P17_.., but I'm not sure if that's to be expected or not.
    It took me a while to figure it out, but when I started looking at the error message closely, I could see that the checksum is identical except for the last two digits, which coincidentally are the same as the ID for this record.
    The checksum computed on the request, clear cache, argument names,
    and argument values (17P17_EVENT_LOG_ID [C6161B29B4C078F68DCF430133407754] ) did not match the checksum
    passed into the show procedure (C6161B29B4C078F68DCF43013340775490). Any thoughts on how to pass a column value with a checksum to a popup window?
    Thanks,

    Welcome to Apple Support Communities
    Windows 8 also works, but only with compatible Macs > http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US Note that you can also install Windows 8 in non-supported Macs by Apple, but you will not be able to install the Windows support software.
    As you have got Mac OS X Snow Leopard and after checking that your Mac supports Windows 8, you need to download the Windows support software from this website > http://support.apple.com/kb/dl1638

  • On my Mac desktop I must have changed a setting so that now when I move the mouse the open windows fly off to the sides and I can't see them. They come back when I move the mouse, but it is so annoying. How can I make the windows not disappear like that?

    On my Mac desktop I must have changed a setting so that now when I move the mouse the open windows fly off to the sides and I can't see them. They come back when I move the mouse, but it is so annoying. How can I make the windows not disappear like that?

    Click on the Hot Corners..  button and look at the four definitions.  In the picture below, if you moved the cursor to the right top of the screen, it would slide all the applications off the screen as you describe and show the desktop.  Set it to "-" to deactivate.

  • Family must have valid payment error

    Family must have valid payment method error pops up when my daughter tries to download form iCloud. It shows my payment method under her user name in family sharing. Why isn't it recognizing it?

    Try going to Settings>iTunes & App Store, tap the ID, choose View Apple ID, then tap Payment Information and confirm that everything looks correct.  Sometimes just checking the payment information will resolve this.  In other cases you may be prompted that your current password isn't secure and needs to be changed.
    Then test Family sharing purchasing again.

  • Request for Safari UI: Safari 3 in Windows Vista must have......

    Safari 3 in Windows Vista must have a full alpha-blending on its UI (anti-aliasing on the edges of the windows) in all editions of Windows Vista that includes Windows Aero UI, the Vista-Style Titlebar controls (just like in iTunes 7.2 in Windows Vista), and shadows under safari's windows.

    Agreed. Though, the Aero-like iTunes caption buttons in Vista still look out of place. Apple should design their Windows apps to fit in better within the Windows ecosystem.
