Flex Data Management Services Tutorial

As part of the Flex Test Drive Server, I wrote a new Flex Data Management Services tutorial. The tutorial takes you through the full FDMS application development life cycle: Java assembler, destination, and client application. Additional topics include:

  • Controlling when changes are sent to the server
  • Controlling client synchronization (autoSyncEnabled)
  • Single Item vs Batch Updates
  • Conflict resolution
  • Locking strategies
  • Fill queries
  • Single Objects vs Collections

Click here to open the tutorial PDF document.

Your feedback on the tutorial and on the Flex Data Management Services in general is appreciated.

Thanks!
Christophe

Note: Refer to this post to download fds-tomcat.zip

ERRATA: On page 4: “On the Java Settings page, specify fdms-tomcat/classes as the Default output folder, and click Finish”. The name of the folder is incorrect: it should read: Specify “fds-tomcat/classes” as the Default output folder (The screen shot is correct).

    I was able to recreate this in both IE7 and Firefox 2 on XP. Not a big deal, but just thought I’d mention it.

    Thanks for the tutorial. Is is possible to trigger The fill method for all clients from the server side (Java that is) ? I need to populate some managed data on the flex side and when any changes are made to this data from the client, it is propogated back to the backend database and subsequently reflected on all clients.
    But, the backend data can be changed without using flex also. So I need to run a scheduler from Java to retrieve the latest data. Is there a way to triggger a refresh of data on all clients using data management from the Java side? I am currently using the messaging service to do this but want to move to the data management service.

    Works great, perfectly actually. The problem is that this Tomcat server has been modified in such a way that the projects developed here can’t be migrated. Can you provide a list of all the modifications to the “standard” FDS configuration files that you put in this project? I’ve been trying to track them all down but it seems the messaging service is still throwing errors when I deploy on a full version of Tomcat. Thanks!

    I haven’t found a solution for the problem of the error “unknown configuration variable ‘compiler.keep-as3-metadata’” found at flex-config.xml.

    I would appreciate any advice.
