[Idrs-dev] Some New Features

[Marc B. <mbo...@ya...>]

Hello everyone.  I have added a couple of features that conform to the
path towords 2.0!

The two new main features are:
1.  Transaction handling support
2.  Automatic Error Handling

Transaction Support is designed allow for a page developer to not worry
about transactions that span multiple connections.  Inorder to use a
transaction in a <db> tag, there must be a transaction tag.  This tag
can have 1 of 2 values:
    BEGIN -- Begin a transaction
    COMPLETE -- If not yet begin, begin a transaction; commit all
    transactions
   =20
Any errors that are generated (part of Automatic Error Handling) or
exceptions force a rollback of all transactions.  There is no longer any
need for programmers to manualy track transactions.

Automatic error handkling allows the IDRS to have a 2-RML Page Form
Entry Process.  When a form is created using the <formInput> an elemnet
called "doc_GoBack" should contain the name of the RML page contaning
the form.  If an error occurrs, the entire request is forwarded back to
the doc_GoBack page and combined with the "paramfirst" option in
<formInput>.  There is also an <error> tag which allows for the display
of an error if one occurrs. =20

Errors are generated using the IdrsScript.createError(description)
causes all business logic to stop and to have the request forwarded to
the doc_GoBAck input parameter if it exists, or an exception will be
thrown with the passed in description going to the error page.

These 2 new features will be featured in a new tutorial.

The next major feature I am working on is EJB support.  I will be
publishing a project paper int he next few days.
