Quick Start: Rendering an HTML form that uses a CSS file using the web service API

The following code example renders an HTML form using the Forms web service API. The name of the custom CSS file that is referenced is custom.css. (See Rendering HTML Forms Using Custom CSS Files.)

/*

 * 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.
