The sample application is easy to install. Simply follow these steps:
- Deploy the LCDS 2.6 Samples WAR to JBOSS and make sure it works. Simply explode the WAR and place it in the “deploy” directory. (You don't have to use JBOSS)
- Open the project zip file, import the project into FlexBuilder 3 and change the build directory to a location in the Samples WAR.
- Compile the Java Classes into the WEB-INF/classes directory of the Samples WAR.
- Point the “-services” compiler directive in the Flex Project at the services-config.xml file in the “config” directory of the project. Also, either integrate the destinations in data-management-config.xml and remoting-config.xml into your WAR config Flex files located in WEB-INF/flex or copy over them. You may have to eliminate a few destinations if you copy over them.
- Compile and run…
The project has good examples for calling two types of Assemblers, a Default Fill and Page Fill Assembler. It also shows how to implement a DataService “Manager” rather than a “Command – Delegate” Pattern for dealing with Data Services in Flex/AIR and also custom sorting and filtering across both Assemblers. There is also an example of using a “DataServiceTransaction” to update a destination through a Remote Object and propagate changes to each client.

Thanks a lot for quick response.
My browser had some issue and was asking for enable java script. I tried in different box and is fine.
Could you please help me with some samples how I can use Producer and Consumer (LCDS) with this frame work
If you want to look at Producer & Consumer Applications you should look at the "Messaging" Functionality in LCDS. There is a simple "Chat" sample that comes with the "samples" WAR. That should get you started....
