Quick Start (Base64): Rendering a form based on fragments using the web service API

The following code example renders a form that is based on fragments using the Forms web service API. The name of the form design is POFragment.xdp. (See Rendering Forms Based on Fragments.)
/* 
    * 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.
