The following code example prepopulates a form with a dynamic
data source. That is, the data source is created at run-time and
is not contained within an XML file or created during design time.
The form is rendered as HTML.
This code example contains three user-defined methods:
createDataSource: Creates an org.w3c.dom.Document object
that represents the data source that is used to prepopulate the
form. This user-defined method returns an org.w3c.dom.Document object.
convertDataSource: Converts an org.w3c.dom.Document object
to a BLOB object. This method accepts an org.w3c.dom.Document object
as an input parameter and returns a BLOB object.
renderPOForm: Uses the Forms service web
service API to render a dynamic purchase order form. The BLOB object
that was returned by the convertDataSource method
is used to prepopulate the form.
All of these methods are
invoked from within the Java servlet’s doPost method.
(See Prepopulating Forms with Flowable Layouts.)
/*
* Ensure that you create the Java proxy classes to use
* base64 encoding. This is required to populate a BLOB
* object with data or retrieve data from a BLOB object.
*
* For information, see "Creating Java proxy classes using Apache Axis"
* in Programming with LiveCycle.
