Building database-driven Flex applications without writing (Client- or server-side) code

One question that developers often ask when they see Flex for the first time is: “how do I write a database application?”

The answer to this question is typically: You use an HTTPService, WebService, or RemoteObject to connect to a server-side component that provides an API to manipulate your data. This approach provides infinite possibilities, but it makes the assumption that you already have that entire backend infrastructure in place. If you don’t, and all you want to do is build a rapid prototype or a simple application, this might look like a lot of work.

In addition to the RPC services mentioned above, the Flex Data Management Services (FDMS) provide a virtually code-free approach to synchronize data between the client application and the middle-tier. That takes care of 50% of our challenge: no data synchronization code to write at the client-side.

FDMS also provides a pluggable adapter and assembler architecture to handle changes at the server-side. As an example of writing a generic assembler, I built a simple JDBC assembler that allows you to develop rapid prototypes and basic database-driven applications without writing a single line of server-side code. All you need to do is specify the database connection information and the table you want to work with in data-management-config.xml.

This assembler is by no means a full featured solution, but it shows the power and flexibility of the FDMS architecture: you could easily extend its capabilities, or build other generic assemblers for existing persistence solutions (a Hibernate assembler is already shipping with the product).

The point is that if FDMS provides a solid architecture to handle the most complex persistence scenarios (with virtually no data synchronization code at the client side), with the addition of specialized assemblers, it can also provide simple solutions to simple use cases, significantly improve your productivity, and deliver end-to-end code-free persistence.

Installing the SimpleJDBCAssembler:

  1. To use the SimpleJDBCAssembler, you need to install the Flex Data Services. If you haven’t already done so, you can download the Flex Data Services here, and follow the installation instructions.
  2. Download jdbcassembler.zip here and expand it in your root directory (the files will be unzipped in a directory called jdbcassembler)
  3. Copy SimpleJDBCAssembler.class in {context-root}\WEB-INF\classes\flex\samples\assemblers. For example, if you installed the integrated server, copy SimpleJDBCAssembler.class in \fds\jrun4\servers\default\samples\WEB-INF\classes\flex\samples\assemblers.

Running the sample application:

  1. Copy the \jdbcdemo directory in the context root of your web application. For example, if you installed the integrated server, copy the \jdbcdemo directory in \fds\jrun4\servers\default\samples.
  2. Open {context-root}\WEB-INF\flex\data-management-config.xml and add the following destination:
  3. 
    
    
        
    
        
            flex.samples.assemblers.SimpleJDBCAssembler
            application
    
            
                
            
    
            
                org.hsqldb.jdbcDriver
                jdbc:hsqldb:/jdbcassembler/db/flexdemo
                product
    true
  4. This example uses an embedded HSQLDB database. Make sure hsqldb.jar is available in the classpath of your web application. For example in {context-root}\WEB-INF\lib. If you are using another database, make sure the JDBC driver for that database is in the classpath of your web application.
  5. Start the server
  6. Access http://localhost:8700/samples/jdbcdemo/simpleclient.mxml. (Change the port number and the context root as appropriate). This is a basic client built with just a few lines of code. You can edit the data inside the datagrid.
  7. Access http://localhost:8700/samples/jdbcdemo/app.mxml. (Change the port number and the context root as appropriate). This is a slightly more sophisticated client. You edit data in a separate form.

Also notice that changes are pushed in real time to all the clients connected to a destination. For example, open the application in two browser sessions, change some data in one session, and notice that the changes are automatically pushed to the second session.

  • Beck

    Yeah, right! But how can I “run” the flexdemo.script to create the needed tables?

    Thanks!

  • christophe

    You don’t have to run that script. flexdemo.script “is” the flexdemo database. That’s how HSQLDB stores a database.

  • Beck

    Thanks, Christophe!

    But I’m getting a SQL table not found exception. Here goes the stack trace:

    java.sql.SQLException: Table not found in statement [SELECT * FROM product]
    at org.hsqldb.jdbc.Util.sqlException(Unknown Source)

    at org.hsqldb.jdbc.jdbcStatement.executeQuery(Unknown Source)

    I would appreciate if you can help me. Thanks again!

  • christophe

    Beck,
    In data-management-config.xml can you specify
    jdbc:hsqldb:/jdbcassembler/db/flexdemo for the database URL? Let me know how that works.
    Thanks,
    Christophe

  • Beck

    The same error, Christophe!

    Here is my data-management-config.xml.

    flex.samples.assemblers.SimpleJDBCAssembler
    application

    org.hsqldb.jdbcDriver
    jdbc:hsqldb:/jdbcassembler/db/flexdemo
    product
    true

  • christophe

    Did you unzip jdbcassembler in your root directory? Basically the jdbc URL is a path to your database (flexdemo.script). So jdbc:hsqldb:/jdbcassembler/db/flexdemo assumes that you have the fully populated flexdemo.script in :\jdbcassembler\db\flexdemo.

  • I too could not get the hsqldb going (I could if I used a absolute path eg: c:\…etc. So i ported it to MySQL. Anyone else doing this or planning to use this great assembler with MySQL a word of advice, I found a little got ya. When you specify the connection string in data-managent.config be sure to use & instead of & when specifying you url eg:
    jdbc:mysql://localhost/flexdemo?user=flexdemo&password=flexdemo
    instead of
    jdbc:mysql://localhost/flexdemo?user=flexdemo&password=flexdemo

    otherwise you will get a unfriendly message like:
    Configuration error encountered on line 230, column 72: ‘The reference to entity “password” must end with the ‘;’ delimiter.’

    if you don´t do this.

    Cheers

    could you suggest a similar working site of flex 2 examples

    regards

    Arthur,

    You’re right – these were working the last time I looked at them a few weeks ago…

    Anyway, there is a different group of chart samples at http://www.quietlyscheming.com/blog/charts/chart-sampler/. Click the “Charting Sampler” link for the demos. You can check out the code for all of them as well.

    Hi Christophe,
    I stumbled upon this blog when I was trying to find a solution to an error i’m encountering while using FDS.
    Basically i’m modifying the Contact Manager FDS sample to use a ready SQL database but just replacing the MSAccess database with SQL DB throws a wierd error.
    I can get my ArrayCollection populated with data from the SQL server but each object is empty.
    My Java wrapper lists all the objects correctly before passing to Flex but somewhere they just break and come in Flex as empty objects.
    This only happens when using an SQL DB and not with an MS Access DB…everything else stays the same.
    The exact error it throws is
    The fill method with parameters ‘[Ljava.lang.Object;’ and destination ‘contacts’ returned null.

    I would appreciate if you can help me. Thanks!

  • TomR

    Arunkumar…
    I had the same problem. I solved it by creating the directory path exactly as specified: for example, mine is:
    \fds2\jrun4\servers\default\samples\WEB-INF\classes\flex\samples\assemblers

    (note that I needed to add a “flex” directory with “samples” and “assemblers” subdirectories)

    After restarting the Integrated Flex Server, it worked.

    Good luck!

    Channel.Connect.Failed
    I was getting this error, that was because I didn’t extract the .zip on c:\, then the database was on the wrong place.

    If you see the data-management-config.xml in the database section we had the following line:
    jdbc:hsqldb:/jdbcassembler/db/flexdemo
    /jdbcassembler/db/flexdemo -> it’s the path to the database, and the base path is c:\ in windows (note that this path is NOT relative to the CONTEXT ROOT!!), you can adjust this to another directory if you wish.

    I have also tested with the fds-tomcat instead of jrun4 sucessfully.

  • Is there any “simple” way to get notified (and the clients updated) when the data changes in the datasource? Example: I have FLEX client app opened in 3 different machines. When data is changed in the (editable) datagrid, Livecycle DS takes care of updating the clients. Datasource is MS SQL server table. Now, if I change the data directly on that SQL table, nothing happens in the FLEX apps. This is important in environments where different technologies (not only Flex apps) interact with a data source. In my case we have a few different financial applications dealing with different sets of data. Any clue on how to deal with that? Updating the clients when changes in the SQL table occur? (without using fill commands polled every few seconds?).

  • Sanjib

    Hi Fernando,

    If the data is manipulated directly in the database without the DS then there is no way this change can be pushed to the clients. Only option would be for the clients to poll the data on a regular interval. Other option that I can think of is to have an insert/update trigger on the table and as part of trigger management somehow notify DS service.

    Thanks,
    Sanjib

  • I’d highly recommend taking a look at the X2O Framework (www.x2oframework.com).

    It’s a web-based data modeling platform that generates the server-side infrastructure (database, server-side, web services) as well as generated AS3 value objects. You don’t have to do any rpc or remoting integration. Instead, it lets you focus on Flex programming and have all your data management there.

  • Why do you have to be like MAcGyver to get flex to do anything. You know Adobe better get this data connection thing user friendly or Silverlight will surpass them for these type of projects. I should be able to go to the “Choose Data Source” feature in Flex, choose my server and database then flex needs to create the needed classes to make this work. I shouldnt need to got to useless blog after another to onlt hit more dead ends.

    • Thank you for the Comer link, Sam. I’ve been familiar with the litmis of java.util.Random but I find it fascinating how the visualization illustrates patterns in the data. The site may be a useful pedagogical tool to drive home the point to students that they shouldn’t trust software-based random numbers.I’ve read some thing about hardware assisted random generators which use environmental factors, such as humidity and temperature, to seed a software generator. Its not foolproof, but I bet it is close enough for this fool.

    Howdy man!
    Great thing i found here, but still i have a question to shoot up, that is , Is that RPC and FDMS is applicable for only the falsh based web apps alone or for Flex AIR applications too…..Though the SQLite provides a convenient way of handling data in offline mode. But i want to make a centralized data provider for all the clients who’d have the AIR app in their system, And there should be an absence of the Server Scripts . .
    Hope to get a quick response…Thanks in advance
