Hi Sudip
              I am using general webservice model only  not adaptive.
             please reply me asap
regards
jalandhar
What kind of model you used to import the web service? If you used adaptive
Webservice model then you require to configure the end point destination in Visual Admin.

  • Stack dump while trying to view the JNDI Tree on a managed server.

    Hi,
    We are running WLI 9.2.3.
    I have a problem when trying to view the managed servers JNDI Tree via the Admin console. The admin servers JNDI tree appears to be fine, but trying to view the 1st managed servers JNDI Tree via the admin console keeps producing a stack dump.
    Does anyone know why this would be? Is it a security issue, judging by the classes below:

    Hi,
    if it works in Chrome then this Problem is related to IE.
    Maybe the URL is to long? IE can "only" handle 2048 Characters.

  • An error occurred while trying to start the Windows Deployment Services server

    After rebooting the server, I cannot start the Windows Deployment Services anymore.
    It worked perfectly before the reboot. When starting it manually these errors appear in the event log:
    The Windows Deployment Services Server service terminated with service-specific error 1460 (0x5B4).
    An error occurred while trying to initialize multicast manager. Windows Deployment Services server will be shutdown.

    This is on server standard beta 3.

    I have removed the server from the WDS, then I have uninstalled the role, rebooted, reinstalled the role.
    When I started the WDS the server was back in there, but when I wanted to start the service I got the message "the windows deployment services configuration is corrupt". I have triggered these commands to reset this:

  • Geeting exception while executing BPM webservice from webdynpro.

    I have created a webservice to start BPM process.
    If I am testing from webservice navigator it works fine and BPM task gets created in my UWL. But when I execute this webservice from webdynpro I get the below error
    Exception on execution of web service with WSDL URL 'http://pepu56:50000/bpm/demosapcom/lngtranslationprocess/StartService?wsdl' with operation 'NewOperation' in interface 'TranslateBPMWSDLFile'

    Edited by: pramod bagauly on Jan 17, 2012 10:18 PM

    I was doing a silly mistake. I was not running my webdynpro application from portal. I was running my application through "Deploy new archive and run" option.
    I got this clue to run this app after login into portal from the fact that when I was running webservice from WSNavigator I was prompted to pass user credential to execute this service.  I had not given any authentication option while creating web service, so just guessed if I run it from portal my user credentials might be taken. And it worked for me.
    I really don't know why I was asked for user credentials in WSNavigator and how my user credentils would have taken when I ran this app from portal. But this is how I am not getting this error.

  • Error while executing the webservice

    hi
    i have exposed  RFC as webservice ,  when i am trying to
    import the webservice (i have used import webservuce model
    deprecated ) , 
    when i am trying to call the webservice its throwing error
    Service call exception; nested exception is: java.net.ConnectException: Connection refused:
    can any one help me out ?

    Hi,
    There are lots of possibilities for this error.
    1) First check if you are able to ping the server in which webservice is present.
    2) You can test the webservice from http://host:port/wsnavigator
    3) If it is working here also, then go to Webdynpro and check if any specific authentication is required for webservice
    4) If nothing works, restart both the servers where webservice is and where you are using webdynpro. Then check the application. It will work.

  • JCO.Server Error while trying to execute a RFC program from SAP

    Hi,
    We are connecting to an external registered server program from SAP via Web Methods.
    The external server program is registered with the SAP Gateway. We have created a TCP/IP RFC destination and are able to connect to the destination successfully via SM59.
    An RFC function is created in SAP and is called using the syntax CALL FUNCTION "/NGN/BAPI_STRE_SEARCH_PROCESS" DESTINATION 'PRDB2B'. We have also handled the COMM_FALIURE and SYSTEM_FALIURE exceptions in the function call.
    We are monitoring the gateway via SMGW and see a connection log to the RFC destination as below
    Number - 10
    LUname - dev01
    TPName - sapgw00
    User - KRAORANE
    Status - CONNECTED
    Symbolic - PRDB2B
    Conversation - 86520353
    Prot - REG
    SAP return code - 0
    CPIC rtn code - 0
    The external program returns results as expected.
    However sometimes the RFC fails and returns the message “JCO.Server could not create server function /NGN/BAPI_STRE_SEARCH_PROCESS”.
    We are not able to figure what exactly is causing this error. Any help will be highly appreciated.

  • Approval task SP09: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'

    Hi everyone,
    I just installed SP09 and i was testing the solution. And I found a problem with the approvals tasks.
    I configured a simple ROLE approval task for validate add event. And when the runtime executes the task, the dispatcher log shows a error:
    ERROR: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'
    And the notifications configured on approval task does not start either.
    The approval goes to the ToDO tab of the approver, but when approved, also the ROLE stays in "Pending" State.
    I downgraded the Runtime components to SP08 to test, and the approvals tasks works correctly.
    Has anyone passed trough this situation in SP09?
    I think there is an issue with the runtime components delivered with this initial package of SP09.
    Suggestions?

    Hi Kelvin,2016081
    The issue is caused by a program error in the Dispatcher component. A fix will be provided in Identity Management SP9 Patch 2 for the Runtime component. I expect the patch will be delivered within a week or two.
    For more info about the issue and the patch please refer to SAPNote 2016081.
    @Michael Penn - I might be able to assist if you provide the ticket number

  • Concurrency Visualizer Extension (VS2013): "An unknown error occurred while trying to start the collection process."

    Not sure if this is the right place to ask about this but since my question concerns an extension I'll give it a shot.
    I'm trying to use the Visual Studio 2013 Concurrency Visualizer extension to debug a simple test console application. I've set executive paging to disabled in the registry as it directed and hit "add SDK to project" in the concurrency
    visualizer menu options. And of course, restarted my computer to apply the settings. When I try to "start [the concurrency visualizer] with current project" I get an error popup:
    "An unknown error occurred while trying to start the collection process."
    I really need the concurrency profiling to start debugging contention in my multithreaded application. Prompt assistance would be much appreciated.

    Hi,
    This forum is to discuss and ask questions about extending and integrating with Visual Studio (using the Extension Manager, building VSX containers for deployment, Visual Studio SDK, and more), Visual Studio Online (REST APIs, service hooks, and OAuth),

  • An error occured while trying to copy the needed DB driver jar files

    When I try to run my web app, I see this error in the Output window.
    Creator will also put up a window essentially saying that I don't have a particular
    data source. But I do have that very data source there.
    The error seems to be pointing to this line in my build-impl.xml file
    <nbdeploy debugmode="false" clientUrlPart="${client.urlPart}" forceRedeploy="${forceRedeploy}"/>

    I'm using postgresql-8.1-404.jdbc3.jar

  • Getting HTTP transport error: when trying to access the webservices

    Hi,
    I have created proxy in JDeveloper 10g. When trying to access the webservices, getting the following error:

    Can anyone help me what might be the reason. If you need more information, I can post it in the next.

    Hi,
    Can you just check your end point URL, and try with appending user name and password at the end of it as parrameters like http://<end point URL>&UserName=admin&Password=admin.
    Other wise check the SOAP request which is going to server using any tool as SOAP UI.

  • I just got v10.6, while trying to run the update, it's telling me that the file is corrupt and cannot be saved. What do I do?!

    I'm running Snow Leopard v 10.6 on a Macbook 4,1. I've got a 500 GB HD and 4GB of Ram. While trying to run the software update (to get me to 10.6.8, I think?) I keep getting an error message around 600 MB that says it's unable to be saved because the file might be corrupt and that it will try again when the software update is ran next time. Why am I getting this message? Is there a way to get the update (so I can eventually get to Lion), without going through the software update screen?
    I'm going crazy with this. I've tried 4 times now and still keep getting the same message.

    Try downloading the stand alone installer here:
    http://support.apple.com/kb/DL1399
    In Safari Preferences, General tab, set "Save downloaded files to: select destop, if it is not in thed rop down select other, then selcet Desktop from the left sidebar. After the download completes click on the installer package on your desktop and follow the prompts.
    Also if possible use an ethernet conection as it is less prone to interference, thus less prone to corruption, and usually faster.
    Hope this helps

  • I finally got my iphone out of recovery mode, after 7.1.1 but now it won't accept my Icloud info and states "An error occrured while trying to save the Icloud account?" What do I do????

    I tried updating my iphone 4 to 7.1.1 and it went straight into recovery mode.... I finally got my iphone out of recovery mode, but now it won't accept my Icloud info and states "An error occrured while trying to save the Icloud account?" What do I do????

    Same situation. I installed iOS 8 beta 4 on my iPhone 5 and a few days later my iCloud account disappeared. My contacts and calendar entries are gone.
    My Mac Mini and MacBook do sync as they should with iCloud.
    When I try to log in to iCloud on the iPhone (the username shows "[email protected]" and password shows "required"), I put in my username and password and tap "Sign In", It says "Verifying" at the top and after a while checkmarks appear next to my username and password. Then I get an error message saying "An error occurred while trying to save the iCloud account". If I tap OK the message goes away, leaving my username and password intact (checkmarks are now gone). If I tap "Sign In" again I get a message saying " '[email protected]' is Already Added. This iCloud account has already been added to your iPhone". If I go back to Settings and then go into iCloud again it's not set up and appears as I stated at the beginning of this paragraph.
    Nothing works and the sync does not occur. Contacts are empty and Calendar has no entries.

  • An error occurred while trying to access the service?

    I'm trying to convert a PDF into Excel but I get the message 'an error occurred while trying to access the service'.
    I have tried logging into my Adobe account online and doing it within there, but once I have exported the file and pressed 'convert' it simply says 'conversion failure' with no explanation.
    My subscription is still valid, so I don't see why the problems?  Has anyone else had this issue and managed to fix it?  I get the error message regardless of whether I'm trying to convert to Word or Excel.
    Any ideas greatly appreciated!!
    Thanks
    Sophie

    Hi SHurcs,
    I'm sorry that you're having such trouble with your ExportPDF subscription. Does this error occur for one particular file, or with any file that you try to convert? What operating system and browser are you using?
    To get us started, here are a few things that you can try:
    In Reader, sign out, and then sign back in.
    Use a supported web browser:  http://www.adobe.com/acom/systemreqs/
    Clear the browser cache.
    If you're using a networked computer, make sure that there are no firewall/proxy settings that prevent you from uploading files to the Internet.
    Make sure that the files you're trying to convert are within the file-size limits for ExportPDF (100 MB).
    If the problem persists, please let us know, and tell us a bit more about the files that you're converting.
    Best,
    Sara
