BlazeDS and ActiveMQ ?

Hi all,
     I read some things about ActiveMQ (version 5). I have been using Flex (version 3) and BlazeDS server and Java work together.
     Java client (publish) send messages to ActiveMQ server and after that this messages send to BlazeDS (from ActiveMQ) and flex client (subscribe) show them
     Also, I search at google to found the connection style beetween ActiveMQ, BlazeDS, Flex and Java. Especially, how configure ActiveMQ contact with BlazeDS ?
     Can show me some link and examples about this problem ?
Thanks.

I would configure your application server to have a short HTTP session timeout. The issue is that when the client application is shutdown without unsubscribing the Consumer the server still thinks the Consumer is alive and queues up messages to be delivered to it. This can be a problem if messages are being pushed at too fast a rate or if you have a long HTTP session timeout because lots of undelivered messages will be hanging around in memory. When the client application is connected to the server it will keep the HTTP session alive so I don't think there is much point in using a long session timeout. Most app servers have a default of about 30 minutes for the session timeout I believe. I would try changing this to be just 1 or 2 minutes and see if it helps your memory problems.
Setting message-time-to-live on the destination may not work if the messages have already been put in the queue of outbound messages to be sent to the Consumer. I would need to take a look at that more closely but I think in this case changing the HTTP session timeout is a better approach.
Hope that helps.

BlazeDS (Turnkey) + ActiveMQ

So, after a lot of reading and experimenting, I was able to get my flex client subscribed to some ActiveMQ topics. The problem I first noticed, however, was the all of the message bodies on the flex side were null and the tomcat console for BlazeDS had the following error:
> JMSAdapter encountered an error while retrieving JMS message body during JMS to Flex conversion: Failed to build body from bytes. Reason: java.io.IOException: ebal.jms.messaging.coa.CourseofAction
That kind of made sense to me, since I never copied any of the classes used by our java applications for BlazeDS, so I stuck the jar in the "tomcat/webapps/blazeds/WEB-INF/lib" folder (I even tried putting them in the "tomcat/webapps/blazeds/WEB-INF/classes" and "tomcat/lib" folders). The complete opposite of what I expected then happened - nothing worked at all. There was absolutely no recognition from the BlazeDS console that any messages were making it from the ActiveMQ topic. I'm completely failing to see how *not* having the JMS object classes works better than *having* them.
Since there is absolutely no documentation on using BlazeDS with ActiveMQ beyond just the configurations, I was curious if anyone has run in to this and found a fix?
Here are the logging settings:
>
                [BlazeDS]
                false
                false
                true
                true
                Endpoint.*
                Service.*
                Configuration
              Service.Message.JMS
               Service.*
Any ideas would be greatly appreciated.

anybody help ??

Getting started with Flex Builder, BlazeDS and Eclipse

Hi,
I'm a java developer looking at RIA for the first time. I'm really excited about BlazeDS and object remoting, but I can't get a working dev environment together. I'm assuming I should use Flex Builder for the client code, Eclipse Europa for the java webapp code, and deploy from both IDEs into the BlazeDS-equipped turnkey-Tomcat. I haven't found a tutorial explaining how to deploy a new webapp with this setup.
The turnkey-Tomcat sample app works fine. Trouble starts when I try to create a new project in Flex Builder. I don't understand the 'debug' deployment that Flex Builder does. Why are there 2 versions of my app, the regular and the debug versions? What is exactly the project structure that I'm supposed to have in Tomcat?
The specific error I encounter when trying to deploy a new Flex project is this:
[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']
I do have a default channel configured for my environment in services-config:
And I do have a valid destination configured in remoting-config (I'm mostly interested in object remoting):
test.ProductService
Here's the client code:
What am I doing wrong? Where can I get help on these specific topics? Also, does anyone have an Ant build file that would automate this sort of deployment?
Thanks!

Hi Peter, I don't have problems passing JavaBeans to Flex. For collections, I used DataGrid, it displayed my collection seamlessly, except I don't get column headers, just a column index number. For receiving a single JavaBean, I had a little more trouble, until I tried to display it with a DataGrid: it displayed a single row that represented my data, with each java property name used as a column header, and object attributes were displayed as 'object'. These 2 experiences led me to these conclusions: - for the collection, Flex converted each element into an ordered list of attributes - for the single bean, Flex converted it into a hierarchy of Maps of attributes I didn't create a Flex value object. Flex is doing it automatically,very much like in JavaScript/JSON: dynamic objects. Here's the remote object markup:  <mx:RemoteObject id="myRemoteObject" destination="productService" fault="Alert.show(event.fault.faultString, 'Error');"> <mx:method name="getProductsCount" result="setProductsCount(event)"> <mx:arguments> <arg1>{productSC}</arg1> </mx:arguments> </mx:method> <mx:method name="getProducts">  <mx:arguments> <arg1>{productSC}</arg1>  <arg2>{pager.pageSize}</arg2> <arg3>{pager.currentPage}</arg3> </mx:arguments> </mx:method> <mx:method name="getProduct" result="goToView()">  <mx:arguments> <arg1>{selectedRecordId}</arg1> </mx:arguments> </mx:method> </mx:RemoteObject> And here's the dataGrid that displays the bean collection: <mx:DataGrid id="myDataGrid" dataProvider="{myRemoteObject.getProducts.lastResult}" change="selectRecord();" width="100%" height="100%" > </mx:DataGrid> Let me know how it goes, I'd be glad to assist if I can.

Some advice please, BlazeDS and some ideas

HEllo all,
I am planning on building an app out, that has two versions, viewer and admin. The admin will be allowed to upload images, and then display an image of choice on the viewers page, and be able to change these images at will, with the viewers page automatically updating.
Kind of like a daynamic image sharing thing.
Now i have been doing some research in how to do this, and stumbled along BlazeDS, and am wondering if something like this is possible with Blaze, i know it can support sending and recieving text based messages really well, but dose it suppose images in the same way ?
Any advice would be great !

hi,
You would still use the messageing system of blaze to tell a user an image has been modified then tehy would download it again, much the same way we did with the video app you would have a key word in the message that triggers a dowload event.
For instance a user uploads an image when the event complete is fired it feeds a message to the server "imageUL:image001.jpg" the serevr then posts a message to all clients "imageED:USR:image001.jpg"
when you get the message it fires the download event because ther first 7 characters ="imageED, the character between the colons is the user id so if you where the one that updated the image you would not proceed to download the image.

BlazeDS and JBoss

Hi All,
I have this BlazeDS problem I need help with....
I need to get Flex application to "talk to" java on the back-end.
For that to work, as you know, I need BlazeDS and, among many, JBoss application server.
I was wondering if someone knows how to integrate BlazeDS with JBoss?
I got stuck with this part....
I've seen some tutorials on the Internet suggesting to just put blazeds.war file into JBoss' deploy directory.
(server/default/deploy/) I think was the path....
I tried that and in fact this worked. I was able to run sample application too.... Strange.
The problem is that I need to control and map my java class to the flex class, which involves editing some config file.
If I'm not mistaken this file is in the blazeds.war file so I can't really edit it. And what if I have to make a change to it?
I can't just figure this whole thing out and run Flex project in Eclipse that "talks to" a java class.
Please note that I have to use JBoss and NOT Tomcat. If I can just correctly integrate BlazeDS with JBoss I'll be half way there already....
Thanks for any suggestions.
Gregg

Hi,
You have 2 options. Probably the preferred method during development is to use an expanded war. Create a subdirectory in the deploy directory named blazeds.war and expand the blazeds war file into it.
If you are ready to deploy the webapp, you can jar the directory back up and deploy it as a war. But as you have seen you cannot make updates to config files or classes on the war file itself.

BlazeDS and JSF

I have an existing JSF (really Oracle ADF) application that I'd like to connect to a Flex front-end rather than rewrite totally in Flex + JSPs for the back-end. BlazeDS will properly instantiate the managed beans through remote object requests, but the FacesContext references in my managed beans are null, as BlazeDS seems to have nothing to do with this context. Does anyone have experience connecting a Flex application to a JSF application properly, maybe through creating his/her own FacesContext factory?

<div class=Section1> color:#1F497D'>Hi,<o:p></o:p> color:#1F497D'><o:p> </o:p> color:#1F497D'>It’s pretty easy to integrate blazeds into an existing application. The war is just an example of how to configure and package blazeds. BlazeDS itself is just a servlet, with a collection of jars and some configuration files. You put the required jars into your WEB-INF/lib, the configuration files into WEB-INF/flex (If I remember correctly), and then map the blazeds message broker servlet in your web.xml file. You can open up the war file and see how it’s configured there and base your configuration on that. Depending on your needs and your servlet container you may have to add a jar file to your container’s lib or classpath.<o:p></o:p> color:#1F497D'><o:p> </o:p> color:#1F497D'>One of the benefits of blazeds is that if you’ve structured your application so that you’ve abstracted the view then you can just plop bds right in there and expose all your services through bds views.

There may be other ways to do this but here's what I would do:
1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
 if(event is
ArrayCollection)
 myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}.

BlazeDS and Flash

Has anyone successfully made any movies / apps with BlazeDS
and Flash?
I have heard it is doable, but when I look around the net
they are all Flex examples.
Any help would be appreciated.
Thanks,
Huntër

Responded to this in the Configuration and Getting Started forum so am just reposting what I wrote there. . .
Hi. I'm not sure anyone has done messaging between a Flash app and BlazeDS. I found some postings where people had gotten Flash apps to do web service calls using the rpc.swc from the Flex sdk. Not sure if these calls were going through BlazeDS as a proxy or directly to the target web service but I imagine that if they got the non-proxy case to work, the BlazeDS proxy case would work as well.
The rpc.swc also contains the client side BlazeDS messaging code so based on what I have read it seems like a Flash app should be able to use rpc.swc to talk to BlazeDS to do messaging remote object calls etc. but not sure how hard it would be to get this working.
This blog posting might help you.

Glassfish v3, BlazeDS, and authentication.

Hi,
I'm looking for documentation about how to configure BlazeDS security with Glassfish v3. I've found this:
http://anachronymous.com/2009/01/flex-blazeds-and-glassfish-part-1.html
...but it's for Glassfish v2. Most of it should be the same, but some of the TomcatValve stuff has changed for Glassfish v3:
http://blogs.sun.com/jluehe/entry/glassfish_v3_adds_support_for
Should I be able to ignore the valve configuration and simply use TomcatLoginCommand since Glassfish v3 is supposed to support Tomcat style valves? I tried adding the following to services-config.xml:
<security>
 <login-command class="flex.messaging.security.TomcatLoginCommand" server="all"/>
</security>
...but upon deployment I get the following error:
javax.servlet.UnavailableException: Cannot create class of type 'flex.messaging.security.TomcatLoginCommand'.
Can anyone point me in the right direction?
Ryan

I'll assume you've got Glassfish using the default 'file' realm for authentication. If not you'll have to adapt my instructions to the realm you're using.
1) Load the glassfish admin console.
2) Navigate to 'Configuration -- Security -- Realms -- file'.
3) Select 'Manage Users' near the top left.
4) Select 'New'
5) Add the user 'tech'. In the 'Group List' put 'tech'. Use any password you like.
6) Select 'OK' to save your user.
7) Navigate to 'Configuration -- Security'.
8) Enable 'Default Principal To Role Mapping'. I can't remember why I have this enabled, so feel free to research it a bit.
9) Select 'Save' to save the changes.
Here is a complete copy of a simple web.xml that I've used:

 </auth-constraint>
 </security-constraint>
</web-app>
Note the MessageBrokerServlet configuration, specifically the <servlet-name>. You probably have something similar. The <servlet-mapping> means all requests to urls like 'http://my.domain.com/contextroot/messagebroker/amf' will be processed by the MessageBrokerServlet. The <security-constraint> configuration restricts all requests to '/messagebroker/*'. Basically all requests to the MessageBrokerServlet will require authentication.
All of the roles in your application need to get listed in the <security-role> section. Each role needs to be mapped to a 'Principal' on the Glassfish server. I'm not positive, but I think the 'Default Principal To Role Mapping' will automatically map users defined as being of the role 'tech' to the 'tech' user (principal) or possibly the 'tech' group. I'm a little unclear on how it works with the group list.
The final parts are the <login-config> and <auth-constraint> sections. The login config defines the realm to use (file in this example). The auth-constraint section says that access to the listed resources should be restricted to users in the 'tech' role.
The whole process is something like this:
1) Only users in the role 'tech' can access urls that match /messagebroker/*.
2) The role of tech is defined and mapped to a principal (or group of principals) within the file realm on the server.
3) The 'Default Principal To Role Mapping' option in glassfish automatically maps the tech role to the tech principal (user) or group (I'm not actually sure which one). I think you'd normall need to configure this somewhere and map the roles in your flex application to groups in your security realm.
Try creating a configuration like the above. Ignore the BlazeDS portion of the configuration to start with and see if you can get it working with just web.xml. After you get that working and know you can actually authenticate to the container (Glassfish), then you can go back to trying to get the BlazeDS side of things configured / mapped.
I hope that helps,
Ryan

How to use Flex builder with blazeds and JBoss

Following the instructions it is pretty easy to set up a project to work with the turnkey tomcat. However, I am having problems with JBoss because the app has to be deployed as a .war file. I can create a war file manually and depoly it no problem. How do I get flex builder to deploy to a war file? I want to be able to debug in flex builder and run at the click of a button.

Hi, I am trying to configure BlazeDS with JBOSS Application Server. I have downloaded BlazeDS binary version - blazeds_bin_3-0-0-544.zip from Adobe. But in the installation steps, it says that copy blazeds.war, samples.war and console.war into <JBOSS_HOME>/server/default/deploy folder. But in this zip, it contains only blazeds.war file only. I have copied it to <JBOSS_HOME>/server/default/deploy folder. I have restarted JBoss. I didn't get any error. But when i give http://localhost:8080/blazeds ... i am always getting "Page not found 404" error. Please help me, if you have detailed steps to configure BlazeDS on JBoss. Thanks for your time.

Weblogic JMS Bridge betwwen WL 11g (10.3.3.0) and ActiveMQ 5.4.2

Hi,
I'm getting following warning when I try to connect two JMS Bridge Destinations (source WebLogic and destination ActiveMQ) through a Bridge.
<Warning> <Connector> <BEA-190032> << eis/jms/WLSConnectionFactoryJNDINoTX > ResourceAllocationException thrown by resource adapter on call to ManagedConnectionFactory.createManagedConnection(): "javax.resource.ResourceException: Failed to start the connection ">
But when I test it by sending message WL does not forward that message to destination queue (ActiveMQ).
When I try to send message individually in WL Queue and MQ Queue from POJO class to test it it works fine.
Please find the setting details

BlazeDS and Flex Client Deployed on Different Servers

Hi, I setup a BlazeDS AMF endpoint on a different server from the server where my Flex app is deployed. I get the following error from my Flex app when trying to use this endpoint:
 faultCode: Client.Error.MessageSend
 faultDetail: Channel.Security.Error error Error #2048 url: 'http://cafrfd1y5css50.itsdo.abc.com:7000/sfaflexservice/amf'
 faultString: Send failed
 rootCause:
 [ChannelFaultEvent
 faultCode="Channel.Security.Error"
 faultString="error"
 faultDetail="Error #2048 url: 'http://cafrfd1y5css50.itsdo.abc.com:7000/sfaflexservice/amf'"
 channelId="my-amf"
 type="channelFault"
 bubbles=false
 cancelable=false
 eventPhase=2]
Btw, this setup works fine when my Flex app runs on AIR or as a Flex app (in a browser) from Flex Builder.
This looks like a crossdomain policy issue, so I setup a crossdomain.xml file on the BlazeDS server. When I point my browser to http://cafrfd1y5css50.itsdo.abc.com:7000/crossdomain.xml, I see the following:
 <?xml version="1.0" encoding="UTF-8" ?>
 <cross-domain-policy>
 <allow-access-from domain="*.abc.com" />
 </cross-domain-policy>
Looks good, but I get the same error...
So I monitored the interaction with Fiddler to see if the crossdomain.xml file is loaded. It is. When the service is activated, I see the following GET command in Fiddler:
 GET /crossdomain.xml HTTP/1.1
 Host: cafrfd1y5css50.itsdo.abc.com:7000
And the response contains the contents of the crossdomain.xml file, so I don't know what's going on.
My configuration is:
-- Browser: IE7 or FireFox v3.5 with Flash Player v10.
-- Flex app uses the 3.4 SDK and is deployed on a Tomcat v6 server.
-- BlazeDS server is WebLogic v9.
-- Endpoint definition from services-config.xml on the BlazeDS server is:
 <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">
 <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/>
 </channel-definition>
-- Endpoint in the Flex app is defined as follows:
 <channel alias="FlexBean">
 <channel_def>my-amf</channel_def>
 <endpoint>http://cafrfd1y5css50.itsdo.abc.com:7000/sfaflexservice/amf</endpoint>
 <destination>FlexService</destination>
 </channel>
Any ideas would be much appreciated...
thanks,
matt

Thanks for the reply, Alex.
I tried setting the domain in the crossdomain policy file to "*", but I got the same error, so I turned on client side logging. The error in the log was:
Error: [strict] Ignoring policy file at http://cafrfd1y5css50.itsdo.abc.com:7000/crossdomain.xml due to missing Content-Type.
See http://www.adobe.com/go/strict_policy_files to fix this problem.
Using Fiddler, I checked the content-type that WebLogic was using for crossdomain.xml. Much to my surprise, there wasn't a content-type in the response, only content-length. So in the web.xml file for this application, I added the following:
<mime-mapping>
 <extension>xml</extension>
 <mime-type>text/xml</mime-type>
</mime-mapping>
Now, the crossdomain.xml file is served with a content-type of "text/xml", and the call to the BlazeDS endpoint works.
Thanks for steering me in the right direction, Alex.
cheers!

Blazeds and Flex Mobile

Hey guy! I need help on a project i'm working on. I just got into Blazeds Remoting for a Flex application because i wanted to use the publish/subscribe model. Coming from a java background this is no problem for me. I've got a Producer component which happens to be in a mobile application and a consumer component which resides on the webser. The Mobile app is meant to publish a mobile phone's GPS details as an object to a server using blazeds messaging capabilities in which a consumer application reads this data and uses it to display the device's location on google maps. The Consumer side seems to be working fine but anytime the producer sends a message i get fault error like so:
Channel.Connect.Failed error Net Connection.Failed :HTTP Status 503:URL: http://cmeunit.swf.<webappname>/messagebroker/amfpolling
Notice the incomplete hostname which is supposed to be acmeunit.swf. I dont know what i'm doing wrong, is there anyway around this.
Any form of help will be appreciated! thanks!

Hi l33tian, I'm running into the same problem. Did you find the solution to this? Any help would be appreciated.
Thank you!
