Quick Start: Rendering an HTML form using the web service API

The following code example renders an HTML form using the Forms web service API. The name of the form design is Loan.xdp. A toolbar is added to the HTML form as well a file attachment. (See Rendering Forms as HTML.)

/*

 * 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.
