How is it possible to map a Dbobject to more than one table. In this class, there is a method to add a new field but there is no argumet require for the table name.

In DBObject, you can't do it directly, there's a one-to-one mapping between a table and a DBObject. A good example of a workaround is the RegisterUser servlet. You'll see the class write data to two different tables with two different DB objects.

I haven't tried it, but maybe the MultiDB* stuff may be of help to you.

The below View is for: "MyView" Portal implementation and would be one component of several on a page. It would display current messages for that user (per the # in preferences):  The below message link would call display in the same format as the forum above.

Comments:

  1. it might be a good idea to include the message number in the message header?
  2. Username is a hyperlink to user profile which they can define what information they want to be available to other subscribers.
  3. Edit button is same as Preferences link
  4. The blue buttons are for use as a "porlet" component in portal.
  5. Preferences will include such things as:
  6. Curious whether Projects should instead be Categories. Somehow I can't help but think these fields can be merged?
  7. Add Admin Preferences table for defining the above colors i.e. for table header, alternating table record colors, table lines, hyperlinks etc.
  8. User "Preferences" can over ride colors for personal preferences.
  9. Continue to simplify and avoid cutter on forms.
