Quick Start (EJB mode): Digitally signing a XFA-based Form using the Java API

The following Java code example signs an interactive form that is rendered by the Forms service. The com.adobe.idp.Document instance that is returned by the Forms service is passed to the Signature service. The signed interactive form is saved as a PDF file named LoanXFASigned.pdf.

/* 
    * This Java Quick Start uses the following JAR files 
    * 1. adobe-signatures-client.jar 
    * 2. adobe-livecycle-client.jar 
    * 3. adobe-usermanager-client.jar 
    * 4. adobe-utilities.jar 
    * 5. adobe-forms-client.jar 
    * 6. jbossall-client.jar (use a different JAR file if the LiveCycle server is not deployed 
    * on JBoss) 
    * 7. jacorb.jar (use a different JAR file if the LiveCycle server is not deployed on JBoss) 
    * 8. jnp-client.jar (use a different JAR file if the LiveCycle server is not deployed on JBoss) 
    *  
    *  The JBoss files must be kept in the jboss\client folder. You can copy the client folder to  
    *  your local development environment and then include the 3 JBoss JAR files in your class path 
    *   
    *  These JAR files are located in the following path: 
    * <install directory>/sdk/client-libs/common 
    *  
    * The adobe-utilities.jar file is located in the following path: 
    * <install directory>/sdk/client-libs/jboss 
    *  
    * The jbossall-client.jar file is located in the following path: 
    * <install directory>/jboss/client 
    *  
    * If you want to invoke a remote LiveCycle server instance and there is a 
    * firewall between the client application and the server, then it is  
    * recommended that you use the SOAP mode. When using the SOAP mode,  
    * you have to include additional JAR files located in the following  
    * path 
    * <install directory>/sdk/client-libs/thirdparty 
    *  
    * For information about the SOAP  
    * mode and the additional JAR files that need to be included,  
    * see "Setting connection properties" in Programming  
    * with LiveCycle 
    *  
    * For complete details about the location of the LiveCycle JAR files,  
    * see "Including LiveCycle Java library files" in Programming  
    * with LiveCycle
