Quick Start: Rendering a form at the client using the web service API

The following code example renders a form at the client using the Forms web service API. The form design named Loan.xdp is located in the C:\Adobe folder. (See Rendering Forms at the Client.)

/*

 * 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.
