The following code example handles a form that is submitted
as XML. The content type value passed to the processFormSubmission method
is CONTENT_TYPE=text/xml. The values that correspond
to the fields named mortgageAmount, lastName,
and firstName are displayed. A user-defined method
named getNodeText is used in this quick start.
It accepts an org.w3c.dom.Document instance and
a string value that specifies the node name. This method returns
a string value that represents the value of the node. (See Handling Submitted Forms.)
/*
* 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
*
* For complete details about the location of these JAR files,
* see "Including LiveCycle library files" in Programming with LiveCycle
