Quick Start: Invoking a service using DIME in a Java project

The following Java code example invokes a process named MyApplication/EncryptDocument using DIME. (See Invoking LiveCycle using DIME.)

An unsecured PDF document based on a PDF file named Loan.pdf is passed to the AEM Forms process using DIME. The process returns a password-encrypted PDF document that is saved as a PDF file named EncryptLoan.pdf .

/** 
    * Ensure that you create Java Axis files that  
    * are required to send a LiveCycle process  
    * an attachment using DIME. 
    *  
    * For information, see "Invoking LiveCycle using DIME" in Programming with AEM forms.
