The following code example optimizes performance by setting
the caching, standalone, and linearized options. A linearized file
is optimized for delivery on the web. (See Optimizing the Performance of the Forms Service.)
/*
* 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.
