The following Flex code example invokes a short-lived process
named MyApplication/EncryptDocument. (See Invoking LiveCycle using Remoting.)
注意: This quick start invokes a LiveCycle process
and uploads an unsecure document. To execute this quick start, LiveCycle
has to be configured to upload unsecure documents. For information
about how to configure LiveCycle to accept unsecure documents, see Configuring LiveCycle to accept secure and unsecure documents.
