Quick Start (Base64): Rendering an interactive PDF form using the web service API

The following code example renders an interactive PDF form named Loan.xdp to a client web browser using the Forms web service API. A JPG file is attached to the form. The form design is stored in the C:\Adobe folder. (See Rendering Interactive PDF Forms.)

    * Ensure that you create the Java proxy classes to use  
    * base64 encoding. This is required to populate a BLOB  
    * object with data or retrieve data from a BLOB object. 
    *  
    * For information, see "Creating Java proxy classes using Apache Axis"  
    * in Programming with LiveCycle.
