Quick Start (Base64): Rendering a rights-enabled form using the web service API

The following code example renders a rights-enabled form to a client web browser using the Forms web service API. The usage rights set in this code example enables a user to add comments in the form and save form data in Adobe Reader (typically this functionality is not available in Adobe Reader). (See Rendering Rights-Enabled 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.
