Quick Start: Decoding barcoded form data using the Java API

The following Java code decodes form data that is located in a PDF form that is saved as Loan.pdf. The decoded data is saved as an XML file named extractedData.xml. This code example converts a org.w3c.dom.Document object into a com.adobe.idp.Document object. (See Decoding Barcoded Form Data.)

/*

 * This Java Quick Start uses the following JAR files

 * 1. adobe-barcodedforms-client.jar

 * 2. adobe-livecycle-client.jar

 * 3. adobe-usermanager-client.jar

 * 4. adobe-utilities.jar

 * 5. jbossall-client.jar (use a different JAR file if LiveCycle ES is not deployed

 * on JBoss)

 * 6. xercesImpl.jar (located in <install directory>/Adobe/LiveCycle8/LiveCycle_ES_SDK/client-libs\thirdparty)

 * 

 * These JAR files are located in the following path:

 * <install directory>/Adobe/LiveCycle8/LiveCycle_ES_SDK/client-libs

 * 

 * For complete details about the location of these JAR files,

When using both an org.w3c.dom.Document object and a com.adobe.idp.Document object in the same application logic, it is good practice to fully qualify both objects.
