pixelcone ajax file upload redirection error using struts 2

Question

I am trying to implement this plugin in struts 2 app. I am able to get the file to server, but when i respond from action with proper div, i get an empty page with current year as only content. In IE i get:

Message: Permission denied
Line: 4
Char: 2462
Code: 0
URI: https://blah.blee.blah.ca/js/jquery/js/jquery-1.7.2.min.js 

When ever i refresh the page (the page that shows 2012 i click back first) and then reload the page, i see that the file is on the server.

Here is my JSP fragment

<div id="main_container">
   <form action="uploadFile" method="post" enctype="multipart/form-data">
        <input type="file" name="pdffile" class="fileUpload" multiple />
        <button id="px-submit" type="submit">Save</button>
        <button id="px-clear" type="reset">Clear</button>
   </form>
   <script type="text/javascript">
        jQuery(function($) {
            $('.fileUpload').fileUploader({
                limit : 1,
                autoUpload : false,
                selectFileLabel : 'Select',
                buttonUpload : '#px-submit',
                buttonClear : '#px-clear',
                allowedExtension : 'pdf'
            });
        });
    </script>
</div>

struts 2 action:

public String uploadFile() {

        String result = Action.ERROR;

        String status = null;

        if (log.isDebugEnabled()) {
            log.debug("doUpload()");
        }

        try {
            showAttachmentDiv = true;
            if (log.isDebugEnabled()) {
                log.debug("doUpload() with filename: '" + this.filename
                        + "' and contentType '" + this.contentType + "'");
                if (uploadedFile != null) {
                    log.debug("doUplaod() with file.getAbsolutePath(): "
                            + uploadedFile.getAbsolutePath());
                } else {
                    log.debug("doUplaod() with file: null ");
                }
            }

            if (uploadedFile != null) {

                if (this.getActionErrors().size() == 0) {
                    AttachmentsUIObject attachment = new AttachmentsUIObject();
                    // the file object is eventually deleted by the fileUpload
                    // utility, so we just copy it.
                    File copiedFile = copyFile(uploadedFile);
                    attachment.setFile(copiedFile);
                    attachment.setType(this.uploadAttachmentType);
                    attachment.setOriginalFilename(this.filename);

                    attachmentsList.add(attachment);

                    // save file code here
                    status = getText(DIV_MESSAGE_UPLOAD_SUCCESS); // on
                                                                    // success
                    // inputStream = new StringBufferInputStream(status);

                } else {
                    uploadedFile.delete();

                    status = getText(DIV_MESSAGE_UPLOAD_FAIL,
                            new String[] { getActionErrors().toString() });

                }

                result = Action.SUCCESS;
            } else {
                addActionError(getText("validation.file.missing"));
                result = Action.INPUT;
            }



        } catch (Exception e) {
            log.error("doUpload()", e);
            addActionError(getText("error.uploadfailed"));

            status = getText(DIV_MESSAGE_UPLOAD_FAIL,
                    new String[] { getText("error.uploadfailed") }); // on

            result = BaseAction.ERROR_UPLOAD;
        }

        inputStream = new StringBufferInputStream(status);

        return result;
    }

struts 2 xml config:

<action name="uploadFile" method="uploadFile" class="xxx.SubmitAction">
     <result name="success" type="stream">
           <param name="contentType">text/html</param>
           <param name="inputName">inputStream</param>
     </result>
</action>

One important note. There is oracle web center. This struts 2 application is accessed from portal. Could this be something related to that?
