New Spring/BlazeDS Integration Test Drive

By Christophe Coenraets | Published: January 27, 2009

UPDATE: I posted a new version of the Test Drive for the M2 build of the Spring / BlazeDS integration project here. Please use that version.

SpringSource recently announced the Spring / BlazeDS Integration project. You can read more about the project and download the bits at http://www.springsource.org/spring-flex.

To help developers get started with the integration, I put together a new “Spring / BlazeDS Test Drive”. This Test Drive consists of a minimal version of Tomcat with BlazeDS and the “Spring / BlazeDS integration” preconfigured and ready to use. It also includes a series of samples running “out-of-the-box” that should allow you to get up and running integrating Flex (and Adobe AIR) with Spring in minutes.

Installation Instructions:

  1. Download the Spring / Flex TestDrive here: http://coenraets.org/downloads/spring-flex-testdrive.zip
  2. Unzip it in your root directory
  3. Navigate to /spring-flex-testdrive/tomcat/bin and start Tomcat (for instance: catalina run)
  4. Open a browser and access http://localhost:8080
  5. Follow the instructions

As always, I’d would love to hear your feedback and your ideas to improve this Test Drive.

    What version of Java are you using? It appears that the “test-drive” package was compiled with a later version.

    Hi,
    Yes the test drive package was compiled with 1.6. I will post a version built with 1.5 shortly.

    I rebuilt it using 1.5. You can download it and try again… It should work with a JRE 1.5 now.

    Hi Christophe,

    Thanks for the Article, this is very useful. But I have couple of questions,
    - Can you provide instructions to deploy this in JBOSS (ver-4.2.2.GA)( that will help a lot)
    - Another big issue I have is, in my company we use the shared web server, so I cannot install BLAZEDS in the Server library. Is there any way around to use BLAZEDS local to my project.

    I really appreciate all your help.

    Thanks,
    Karunya

    Building the examples from source using Maven would be a really nice touch!

    A lot of people using Spring/BlazeDS will have their code built with a CI server and typically maven. Documentation on doing this and not messing up the WTP tools in Eclipse is non existent.

    Chris

    Thanks for creating the test drive kit. It gives a stable starting point.

    Please can you suggest how we go about using AMF for the following set up: We have outsourced Flex develpment and are managing J2ee development internally. I am not sure how can flex team access remote objects ..Should we pursue AMF3 / blaze DS route . Earlier we were using Web service based approach and hence it was relatively easy for the flex developers to communicate with the server side components.

    Appreciate your help / suggestions of the same

    Thank you very much Christophe. I adapted your tutorial for DM Server, for those who are interested here it is the link to integrate
    Christophe’s samples in DM Server.

    I can run the sample using Tomcat, but the same won’t run on any other server, like WASCE v2 or weblogic 10.I created a WAR file and deploy it. The page loads and when clicked on get data nothing happens. so can anyone help on what are the things to check, I am sure all the required jars are in place, because I don’t get any error, when running in tomcat. I did not modify much on the xml. (I just removed the JDBC part and i am returning the output but manually adding data to list, But i guess the request does not even reach the bean)… So please guide me.

    Chris,

    Can you please post the project files for fb3/eclipse.

    Instruction to import the source and build deployable components will work too.

    Thanks alot for the good work.

    Christophe,

    Very helpful. I especially appreciated the design progression on the contact manager.

    Worked fine on my Mac after I ran “chmod +x *.sh” in the tomcat/bin directory.

    What’s the best way to build? I didn’t see any e.g. ant files.

    Thanks,

    Hello Christophe,

    Ref:: Spring BlazeDS Integration–> Integration with Spring Security

    I am trying to integrate Spring Security with BlazeDS. I have two configuration files :applicationContext.xml, and applicationContext-securitycheck.xml.

    However, when I run the app on server I get the following error::
    Error creating bean with name ‘org.springframework.web.servlet.handler.SimpleUrlHandlerMapping#0′ defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘mySpringManagedMessageBroker’ defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: FlexConfigurationManager requires a non-null ServletConfig – Is it being used outside a WebApplicationContext?

    Can you let me know if this is doable? Also, when is the next release for this slated?

    Could you make an example project of BlazeDS multi module application with Maven?

    Nice example.
    I’d like to test my code.
    I’ve some questions:
    - How to configure it if context is not ROOT ?
    - I try to do a project in fb3 from a copy of spring-blazeds-101.
    I get this error : [RPC Fault faultString="[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']” faultCode=”InvokeFailed” faultDetail=”Couldn’t establish a connection to ‘productService’”]
    Can you help me or do you have a fb3 project or better a maven project ?
    Thanks a lot

    Great Christopher… Nice explanation. Many thanks…

    I too tried implementating your approach in my project and getting the same problem as posted

    [RPC Fault faultString="[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']” faultCode=”InvokeFailed” faultDetail=”Couldn’t establish a connection to ‘productService’”].

    Do let me know your thoughts.

    It’s the first time I commented here and I must say you share us genuine, and quality information for bloggers! Good job.
    p.s. You have a very good template for your blog. Where did you find it?

    miracle you got this running with the erroneous documentation. I’ve followed the docs to the letter 10 times, and it never forwards on to the amf gateway.. I don’t know how you did it either, because using your config file gives me this:

    Your example would be infinitely more useful if you actually posted the .project files too! It’s nice to see it works, but tbh, it feels more like ner ner ner ner ner, than actually any help right now.

    This is what I get if I turn your server into an eclipse project and run on tomcat:

    I’ve a small problem with a very simple POJO using RemoteObject and the Spring-BlazeDS integration framework you have provided.

    I added my simple POJO class (Repeater) and its config to web-application-config.xml:

    ————-

    ————-

    The MXML of the Flex app, and declaration of RemoteObject:

    ————-

    PROBLEM: Flex error: “Couldn’t establish a connection to ‘repeater’”.

    I know my Repeater POJO is loaded by Spring, because its constructor prints a message to screen when I start the BlazeDS server. But the Flex app can’t access it.

    THANKS!

    DOUBLE POST because first post filtered out the XML.

    I’ve a small problem with a very simple POJO using RemoteObject and the Spring-BlazeDS integration framework you have provided.

    I added my simple POJO class (Repeater) and its config to web-application-config.xml:

    ————-

    Implementation of Repeater
    bean id=”repeaterSvc” class=”flex.spring.samples.repeater.Repeater”>

    /bean


    bean id=”repeater” class=”org.springframework.flex.messaging.remoting.FlexRemotingServiceExporter”>

    /bean

    ————-

    The MXML of the Flex app, and declaration of RemoteObject:
    mx:RemoteObject id=”ro” destination=”repeater” fault=”faultHandler(event)”>

    /mx:RemoteObject

    ————-

    PROBLEM: Flex error: “Couldn’t establish a connection to ‘repeater’”.

    I know my Repeater POJO is loaded by Spring, because its constructor prints a message to screen when I start the BlazeDS server. But the Flex app can’t access it.

    THANKS!

    Awesome post Chris. What is the best way to integrate Spring with Livecycle Data Services? Is it similar to the way you integrate it with BlazeDS?

    DeGroot points out that, while customers and suppliers may have their own ways of calculating dielectric constant, having a standardized IPC methodology will allow for better benchmarking of such attributes as frequency, classes of material types, and standardized test structures that are similar to practical signal traces.
