问题解决了。

public void fileUploadListner(UploadEvent event) throws Exception {
    UploadItem item = event.getUploadItem();
    File imageFilePath = item.getFile();        
    uploadDocDataBean.setDocname(item.getFileName());
    uploadDocDataBean.setDocsize(String.valueOf(item.getFileSize()));
    InputStream fileInputStream = new FileInputStream(imageFilePath);
    byte[] data = new byte[(int)imageFilePath.length()];
    fileInputStream.read(data, 0, (int)imageFilePath.length());
    fileInputStream.close();
    uploadDocDataBean.setDoc(data);
}
