AttachmentViewCmd
The AttachmentViewCmdImpl
will retrieve the attachment content
from database and return the stream as DirectView to browser if the
attachmentURL is same as attachment_id If the attachmentURL is not the same as
attachment_id, we will assume that the attachment is not stored as BLOB in
attachment table in database. We will open up the file as specified in
AttachmentURL and return the stream as DirectView to browser
AttachmentViewCmdImpl is only intended to be extended and not used directly .
The AttachmentViewCmdImpl is not registered in the URLREG or CMDREG
