Direct Known Subclasses:

public class AttachmentViewCmdImpl
extends ControllerCommandImpl
implements AttachmentViewCmd

This class will retrieve the attachment content from the database and return the stream to the browser as a DirectView object if attachmentURL is same as attachment_id. If attachmentURL is not the same as attachment_id, it will be assumed that the attachment is not stored as BLOB in the attachment table in the database. We will open up the file as specified in attachmenturl and return the stream as a DirectView object to the browser. AttachmentViewCmdImpl is only intended to be extended and not used directly. AttachmentViewCmdImpl is not registered in the URL configuration or the command configuration.
