package flex.messaging does not exist


Not applicable
When I try to compile a new .java file based on in the examples application I keep getting this error.

"package flex.messaging does not exist"

Where can I get the flex.messaging package - or am I just doing something wrong?

Jordan, imports three Flex messaging classes:

1) flex.messaging.MessageBroker

2) flex.messaging.messages.AsyncMessage

3) flex.messaging.util.UUIDUtils

These classes must be included in the build path. If you have a license for LiveCycle Data Services ES, these classes are available in ../WEB-INF/lib. If you do not have a license for LiveCycle Data Services ES, you can get these classes in the open source version of Data Services ES called BlazeDS.
