DTD reference not avaiable

Hi,
Since yesterday we observe that http://java.sun.com/dtd/ URL is responding very badly.
Most of the time connection times out or reset. I tried from different different network and same issue observed.
Because of this application build fails.
Is there any forum where sun[oracle] acknowledges the downtime maintenance or issue and by when it will get resolved.
We are using some product and cant remove reference from the web.xml of product file.
Any guidance on this will be appreciated.
Thanks & Regards,
Kevin Chheda

You ought to cache that file locally rather than relying on it being available 24-7 on the web.

  • Adding DTD reference in xml

    hi,
          This way i am creating xml,
            var cAcrobat += "<Root>";
            cAcrobat += "<Sample>" + "Something" + "</Sample>";
            cAcrobat += "</Root>";
            this.createDataObject("Acrobat.xml", cAcrobat);
            var Acrobat = this.getDataObjectContents("Acrobat.xml");
            cAcrobat = util.stringFromStream(Acrobat,  "utf-8");
            var myXML = XMLData.parse(cAcrobat, false);
            var cAcrobat = myXML.saveXML('pretty');
            var Acrobat = util.streamFromString(cAcrobat, "utf-8");
            this.setDataObjectContents("Acrobat.xml", Acrobat);
    and as a result it is creating an xml file as an attachment to pdf,  as follows,
      <?xml version="1.0" encoding="UTF-8" ?>
    - <xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
    - <Root>
      <Sample>Something</Sample>
      </Root>
      </xfa:data>
    but i want to add DTD reference to xml file before the Root node  and after adding it should create xml like this,
    <?xml version="1.0" encoding="UTF-8" ?>
    "<!DOCTYPE  Some-application SYSTEM 'file:C:/SomeFolder/Test.dtd'>";
    - <xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
    - <Root>
      <Sample>Something</Sample>
      </Root>
      </xfa:data>
    please tell me how to add this dtd reference in xml file, and whater i am doing above is correct or not?

  • Ignore DTD reference in message monitoring (SXMB_MONI)

    Hi All,
    My Inbound Message (to be delivered to the target system) needs to have DTD reference as the target system mandates it.
    In the mapping I have added the DTD Reference (<!DOCTYPE .../>).
    Although the target system is happy ,massage monitoring is complaining that the DTD is missing when I want to display the XML message.This is a support issue as the inbound XML message is not diaplayed  in SXMB_MONI.
    Is there any way to work around it - Configuration or putting the DTDs somewhere in XI server.
    Thanks in Advance,
    Bikram

    Rather than add the DTD reference in a message mapping, you could try add it in a Java module attached to the receiver/outbound module-chain of your target communication channel.  This way the DTD line would not get added until after the message has left the integration server.
    Check out the following guide:
    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/02706f11-0d01-0010-e5ae-ac25e74c4c81
    Let me know how you get on.
    (+ please assign me some forum points if you found this useful).

  • Ignoring a DTD reference

    I'm trying to load an existing XML document that specifies the DTD as a relative reference:
    <!DOCTYPE Overlay SYSTEM "overlay.dtd" >
    When I have the DTD in the same directory as the XML file things work, when it's not there it fails with a file not found exception as expected:
    java.io.FileNotFoundException: C:\...\overlay.dtd (The system cannot find the file specified)
    However it still fails with that even when validation is disabled.
    Is there any way to have the parser completely ignore the DTD reference?

    I'd suggest you shouldn't be putting those DTD references in your XML if they aren't going to be used. However perhaps you could write your own EntityResolver that catches references to that DTD and replaces them with a reference to some other DTD... maybe a trivial one that does no validation.

  • XSDBuilder fails to resolve DTD references

    I am evaluating XDK 9.2.0.5.0 for Java and have encountered a problem
    with XML Schema support.
    I am using XSDBuilder to build an XMLSchema object from several .xsd
    files. The main .xsd file is secext.xsd, and this file imports other
    .xsd files. I assign an EntityResolver to the XSDBuilder so that all
    imported schema files will be read from my local file system, rather
    than being retrieved from the Internet.
    XSDBuilder does call my EntityResolver to resolve the import
    statements in the XML Schema files; however, it fails to call my
    EntityResolver to resolve XMLSchema.dtd reference in the DOCTYPE
    declaration of xml.xsd.
    I am using Oracle XDK version 9.2.0.5.0 on Solaris 8 with Java 1.4. I
    have also tried version 10.1.0.0.0 beta and received the same results.

  • External definition, dtd references

    Hi,
    My openTRANS_ORDER_1_0.dtd is refering to "openbase_1_0.dtd
    When I create the external definition both dtd’s is imported
    openTRANS_ORDER_1_0_dtd
    openbase_1_0_dtd
    openTRANS_ORDER_1_0.dtd has a External reference :
    Source: openbase_1_0.dtd
    Name: openbase_1_0_dtd
    and openbase_1_0_dtd has also filled out the
    Source : openbase_1_0_dtd
    So the dtd reference should be OK now !
    But when I try to create the Message Interfaces it is not possible to choose
    Any Elements under the external definition openTRANS_ORDER_1_0_dtd.
    I would expect to could choose the ORDER element
    Here is the openTRANS_ORDER_1_0.dtd.:
    &lt;!ENTITY % OPENBASE SYSTEM "openbase_1_0.dtd"&gt;
    %OPENBASE;
    &lt;!ELEMENT ORDER (ORDER_HEADER, ORDER_ITEM_LIST, ORDER_SUMMARY)&gt;
    &lt;!ATTLIST ORDER....."standard"&gt;
    &lt;!ELEMENT ORDER_HEADER (CONTROL_INFO?, SOURCING_INFO?, ORDER_INFO)&gt;
    &lt;!ELEMENT ORDER_INFO (ORDER_ID, ALT_CUSTOMER_ORDER_ID*, ORDER_DATE,  ...)&gt;
    &lt;!ELEMENT ORDER_ITEM_LIST (ORDER_ITEM)&gt;
    &lt;!ELEMENT ORDER_SUMMARY (TOTAL_ITEM_NUM, TOTAL_AMOUNT?)&gt;
    Can any one explain why I cannot choose any elements when creating my message definition !
    Frank

    u will be able to choose only the message type in the message interface and not the elements of the message type in message interface.

  • "An error has occurred:Object reference not set to an instance of an object."

    This error message comes up with a user in InfoView.  The user schedules a report, updates parameters, and the report kicks off successfully.  But then a few minutes later, this error is received.    This occurs sporadically, regardless of the length of time of report or amount of data being retrieved.  Sometimes the report runs to completion.  Other times this error message occurs.
    Has anyone seen this before and have any thoughts?
    Thank you.
    “An error has occurred:Object reference not set to an instance of an object.”

    Are you able to replicate the issue both in Java and .NET InfoView?
    For .NET InfoView, sometimes the "An error has occurred: Object reference not set to an instance of an object" error shows up after the .NET Framework is upgraded to 2.0

  • "Object reference not set to an instance of an object" when opening designer

    I have a Windows Forms project which was originally developed in Visual Studio 2010. I migrated the project to VS2013, and now every time I open the project's main form, the designer complains of a null reference. If I hit "Ignore and Continue",
    the code compiles just fine. The error in question appears in the "Windows Form Designer generated code" region. Even more curious, the line in question is not the first reference to the object. It's as if the first few times it needs to interact
    with the object, it's fine, then at a certain point it becomes null.
    Here is the call stack for the error:
    at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component,
    Object value)at
    Microsoft.VisualStudio.Shell.Design.VsTargetFrameworkPropertyDescriptor.SetValue(Object
    component, Object value)at
    System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializePropertyAssignStatement(IDesignerSerializationManager
    manager, CodeAssignStatement statement, CodePropertyReferenceExpression
    propertyReferenceEx, Boolean reportError)at
    System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAssignStatement(IDesignerSerializationManager
    manager, CodeAssignStatement statement)at
    System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager
    manager, CodeStatement statement) 
    And here is the code in question:
    this.optionsControl.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); 
    this.optionsControl.IsAsciiMode = false;           
    this.optionsControl.Location = new System.Drawing.Point(3, 3);
    this.optionsControl.LogControl = null;           
    this.optionsControl.Name = "optionsControl";           
    this.optionsControl.PlugInManager = null;           
    this.optionsControl.PortFacade = null;           
    this.optionsControl.Size = new System.Drawing.Size(613, 259);
    this.optionsControl.TabIndex = 0;
    The problem is reported at the third line, "this.optionsControl.Location = new System.Drawing.Point(3, 3);".

    Hi Eric,
    I have made a research about your issue, and I found it might be caused by the usercontrol in the project. Was “this.optionsControl” a UserControl? It seems that this issue was difficult to handle.
    If possible, I would recommend you recreate this control in a new project.

  • "object reference not set to an instance of an object" after update datasource lightswitch

    I'm using Latest Visual Studio 2013 Ultimate (2013.3) and when I attempt to open "update datasource"  it throws an error
    "Object reference not set to instance of an object." 

    It's quite possibly an issue with the data source definition being dependent on a newer version of a lightswitch framework DLL.  When I've hit these kinds of issues I've simply deleted the datasource, run a nuget refresh and added the datasource again.
     If you have any code or queries, save a copy of the code-behind files and jot down the details of the queries before you try this.
