Quick Start (EJB mode): Removing password-based encryption using the Java API

The following Java code example removes password-based encryption from a PDF document named EncryptLoan.pdf. The master password value used to remove password-based encryption is PermissionPassword. The unsecured PDF document is saved as a PDF file named noEncryptionLoan.pdf. (See Removing Password Encryption.)

/* 
    * This Java Quick Start uses the EJB mode and contains the following JAR files 
    * in the class path: 
    * 1. adobe-encryption-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 the LiveCycle Server is not deployed on JBoss) 
    * 6. jacorb.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss) 
    * 7. 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
