Error occurred when trying to access DC in web dynpro

Hi,
Have everyone ever encountered an error saying <b>"Unhandled exception caught in event loop"</b> when trying to access DCs in web dynpro?  I tried to add a new action to my main compnent after a used web dynpro component (DC) was added but the web dynpro would shut down automatically.  The web dynpro would shut down accidentally and automatically even when I clicked the interface controller.  Some times, the error log would repport "<b>org.eclipse.swt.SWTError: No more handles</b>"...it has driven me crazy.  I could not go further.  Can someone tell me what I have done wrong to get these errors?!!
thanks,
Zita

Dear Zita,
I error is related tot he message which you get "No more handles".
This definitelly means that there is a bug and old files are not closed , thus the number of handles on OS level is exceeded.
The exact way to debug the "handles" leak is with applying SAP JVM Profiler, using the I/O Analysis feature.

I am on a Mac Book Pro with Yosemite (don't upgrade it slows your Mac badly) and whenever I try to convert a pdf to a doc I get 'an error occurred when trying to access the service', can anybody help me please?

    Are you getting this error: "an error occurred when trying to access the service" while trying to access the service via Reader.

  • When I click Convert to Word docx, I receive the error message -- "An error occured when trying to access the service." This has been happening for about a week.

    Export PDF will not convert a pdf to MS Word. This failure has been going on for about a week. The error message is "An error occurred when trying to access the service." What can I do to get this working again?

    Hi,
    It seems it was working fine earlier.
    Is this happening with all files?
    You can try using different browser.

    I am using Adobe Reader with paid up service through May 2015.  When I attempt to convert a file either to PDF or from PDF, I get the error message, "An error occurred while trying to access the service".  What do I need to do to get access to the service I have paid for?

    Hi DeaconTomColorado,
    Please see "Error occurred when trying to access this service" when logging on to Acrobat.com.
    Adobe has just released an update to Adobe Reader, so if you're accessing the service via Reader, please let us know whether the update helps resolve the issue.

  • Receive error message "An error occurred while trying to access the service" when I try to convert a file?

    When I attempt to convert a file, either to PDF or from PDF I receive the error message "An error occurred while trying to access the service" what can I do to resolve?  I already applied updates and attempted to fix?

    You could always sign into Acrobat.com directly and use the service through the web site if it's a critical need.

  • Error occurred while trying to access framework

    Did some changes to master rule collection u2013 switched from default desktop to light desktop u2013 and when trying to go back, something went wrong!!!
    Error occurred while trying to access framework page: "pcd:portal_content/com.sap.pct/every_user/general/defaultAjaxframeworkContent/com.sap.portal.afpDesktop/frameworkPages/com.sap.portal.AFPpage",The object does not exist or you are not authorized to access it.If this problem persists, contact your system administrator.
    Activated SAP* user and logged in, but still the same issue!
    Tried also the following url
    http://myhost:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fevery_user!2fgeneral!2fcom.sap.portal.frameworkpage
    with the response:
    Error component failed , reason : Access is denied: pcd:portal_content/com.sap.pct/every_user/general/com.sap.portal.frameworkpage - user: Guest, Original Exception : Access is denied: pcd:portal_content/com.sap.pct/every_user/general/com.sap.portal.frameworkpage - user: Guest,
    What next to do?

    Dear Customer,
    Try to access the Default Framework using the following paterns:
    Default framework page: /irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fevery_user!2fgeneral!2fcom.sap.portal.frameworkpage
    Desktop & Display rules: /irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fadministrator!2fsystem_admin!2fsystem_admin_role!2fcom.sap.portal.system_admin_ws!2fcom.sap.portal.themes!2fcom.sap.portal.portalDisplayRules
    This can be used whenever the desktop assignment to the user which you are logging on with has been removed somehow. If this occurs, the user won't be able to see any content after logging on to the portal and the following error will be shown: "Error occurred while trying to access desktop: "portal_content/themes/sap_chrome". The object does not exist or you are not authorized to access it. If this problem persists, contact your system administrator."
               If this occurs, you can use the address above to restore the desktop rules at least for your user so that you can log on to the portal again with no problems.

    This solved my questionRe: iTunes Error (-1202)
    Dec 28, 2012 6:35 PM (in response to crossi85)
    I am having the same issue on my iMac.  It occurred after the last iTunes update.  Apple support offered no real solution.  They tried "clearing" my Wish List, but that didn't work, and advised me to re-install iTunes.  However, I tried clicking the "My Wish List" link on the right side of the iTunes Home page, instead of the one I usually use under the "Manage" column near the bottom of the screen - and it worked!  Furthermore, my Wish List was still intact even though they had supposedly cleared it.  So, in my case, the problem appears to be the iTunes site, and not my computer.  My solution: Try accessing the Wish List from a different link within iTunes.
