    File upload component is not working in Smart Client 8.1

    The application have Struts 2 and Smart Client 8.1 both plug-in(s).
    Please note application deployed on Weblogic 10.3 server.

    Case 1: When the Struts filter has enabled the file file uploader component does not upload the file and return null on DMI Layer.

    Case 2: When we disable Struts 2 filer then file uploader workes but, it not upload complete file. Where as the total file size is just 10-15 KB.
    We got "org.xml.sax.SAXParseException: Premature end of file." Exception.

    {Stake trace}

    {Stake trace}



    below are the code snippets.

    1. In DS file we have declare a field type as binary :- report.DS.xml
    <field>
    <name>reportdata</name>
    <title>JRXML File</title>
    <type>binary</type>
    <showFileInline>true</showFileInline>
    <required>true</required>
    </field>

    2. DMI Class code:- ReportDMIImpl.java
    Map valueMap = dsRequest.getValues();
    Long reportID = (Long) dsRequest.getParameter("reportid");
    ISCFileItem fileItem = dsRequest.getUploadedFile("reportdata");
    if(fileItem== null && reportID!= null && reportID> 0){
    return DM2Utils.getFailureResponse(dsResponse, new ReportDTO());
    }


    Please let me know if more information is required.

    Thanks!

    This error doesn't suggest that the file is truncated during upload, just that it's an invalid file for whatever is parsing it (which is a third-party library).

    If you discover that the file *is* truncated however, then that would be due to one of the remaining filters that are still involved in processing the request (according to the stack you showed).

      This is not only the recent uploaded file but also it is happen to other files.

            The problem with the file truncation is resolved if I remove the struts2 filter.

            If I add back the struts 2 filter, the below API on the DMI layer returns fileItem as null.

            ISCFileItem fileItem = dsRequest.getUploadedFile("attachedReport");

            I have verified that I get the inputstream on my DM2ApplicationFilter but when DMI layer is invoked, this inputstream is null.

            Please advice what can be the resolution for this issue.

              The surest resolution is to stop using Struts2, either entirely or for this particular filter. Struts2 is an older architecture similar to JSF, there's no reason to be using it with SmartClient.

              Beyond that, you will need to file a bug with the Struts team (it's not our bug).
