Quick Start: Invoking a service using BLOB data over HTTP in a Java project

The following Java code example invokes a process named MyApplication/EncryptDocument using data over HTTP. (See Invoking LiveCycle using BLOB data over HTTP.)

An unsecured PDF document based on a PDF file named Loan.pdf is passed to the AEM Forms process using SOAP over HTTP. The PDF file is located at the following URL: http://hiro-xp:8080/FormsQS . The process returns a password-encrypted PDF document that is saved as a PDF file named EncryptedDocument.pdf .

/** 
    * Ensure that you create Java proxy files that consume 
    * the the LiveCycle service WSDL. You can use JAX-WS to create 
    * the Java proxy files.   
    *    
    * This Java quick start uses BLOB over HTTP to invoke a short-lived process named 
    * EncryptDocument. For information, see  
    * "Invoking LiveCycle using BLOB over HTTP" in Programming with AEM forms.
