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.
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 the org.w3c.dom.Document object.
convertDataSource: Converts an org.w3c.dom.Document object
to a com.adobe.idp.Document object. This method
accepts an org.w3c.dom.Document object as an input
parameter and returns a com.adobe.idp.Document object.
renderPOForm: Uses the Forms service Java
API to render a dynamic purchase order form. The com.adobe.idp.Document 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.)
/*
* This Java Quick Start uses the following JAR files
* 1. adobe-forms-client.jar
* 2. adobe-livecycle-client.jar
* 3. adobe-usermanager-client.jar
*
* (Because Forms quick starts are implemented as Java servlets, it is
* not necessary to include J2EE specific JAR files - the Java project
* that contains this quick start is exported as a WAR file which
* is deployed to the J2EE application server)
*
* These JAR files are located in the following path:
* <install directory>/sdk/client-libs/common
