The LCDS Dev Guide (Chapter 17) and LCDS LiveDocs mention
some Java Helper classes but do not specify where they are located.
The following Flex Java packages:
flex.acrobat.pdf.XFAHelper;
flex.messaging.FlexContext;
flex.messaging.FlexSession;
flex.messaging.util.UUIDUtils;
...are contained in the JAR files located under WEB-INF/lib
in flex.war (the exploded LCDS install folder deployed on your Java
server).
Reference them in Eclipse: Project properties > Java Build
Path > Libraries > Add External JARs. Then clean and rebuild
your project.
