Hi All,
I wanted to solicit some ideas and suggestions for this session. My
current thought is to have a selection of practices which I will
present and then get comments (debate) from the other members of the
panel. The idea being that we don't all see them with the same eyes
and some of them are likely to provoke some spirited discussion (not
to mention the obligatory "If you are using Wonder..." comments). I'd
like to think of them as "Quite Good" rather than "Best" practices.
I'll leave some time at the end for audience questions.
Some ideas for inclusion are:
- using EOPrototypes
- use of peer and nested editing contexts and the then needed locking
of editing contexts
- generate your EOs and use the Generation gap pattern (though with
Entity modeler, you have to fight to not do this)
- use generation to create common worker methods
- generate String constants to avoid hard coding attribute and
relationship names
- use qualifiers objects rather than qualifierWithFormat
- check for null in awakeFromInsertion (mostly a JavaClient issue)
- avoid EOAccess classes in your EO methods
- use stateless components and store state in the page
- handling checked exceptions with NSForwardException
- keep WOComponent Java files focused on the UI
- watch the generated SQL (for batch fetching and optimization index
needs)
- using formatters for reusability
- don't repeat yourself, use common build files
- block direct page requests
- use class name to create component
- plan to handle errors from saveChanges()
- use custom EOGenericRecord subclass
- use embedded frameworks
Things that are best practices, but can't be covered properly:
- use Wonder
- use source control
- use log4j
- unit testing (TestNG or JUnit)
- functional testing (Selenium)
