Quick Start: 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 ES.
