Dispatch Action Questions

["Faus, Lee" <Le...@compuware.com>]

I have an application that I am trying to architect using Struts.  One of
the questions we have is the advantage/disadvantage to each of the following
approaches.

 

1. For each table in the database, we plan on having one form bean, and 4
action classes that will extend an ActionBase class.  The four actions that
will be used are CreateSomething, ReadSomething, UpdateSomething,
DeleteSomething.  This will give a good infrastructure for our application
as it grows and it will allow us to build out a "pattern" for the entire
application to let people know how they should build out their actions.  On
the downside, this is going to create a huge struts-config file as there are
about 40 tables in the application.  Imagine what would happen on an
application that has 1,000 tables.

 

2. Look at the overall application and make decisions to have one form bean
per use case, and one action per use case that will allow us to use the
Dispatch Action to pass in a parameter for create, read, update, delete and
have methods in the Action class to perform the above action.  This is not
as straight forward because a developer can interpret the use case
differently and allow for some ambiguity as to the building of the form
beans and actions and can make maintenance a nightmare.  This would shrink
our overall struts-config file to a point that it would be more manageable
but at the sake of readability and manageability.   

 

I understand I could create multiple "struts-config" files for each use case
and this is another solution we are investigating.  What I need is best
practice so we can standardize on a common architecture for all applications
moving forward as well.  I have seen examples of each on this forum and in
the different struts books, so I am confused as the best approach moving
forward.  Any help would be greatly appreciated.
