help to Configure a Data Management Service destination

[flex_freddyboy]

Hi, I have a problem with the sample here :
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&f...



with flex builder I have the following error : Destination
'notes' must specify at least one channel.



somebody can tell me what I need to do to resolve my problem
?



thanks

you have your channels setup in
WEB-INF\flex\services-config.xml file - search for

<channels>

....

<channel-definition id="my-rtmp"
class="mx.messaging.channels.RTMPChannel">

<endpoint uri="rtmp://{server.name}:2037"
class="flex.messaging.endpoints.RTMPEndpoint"/>

<properties>

<idle-timeout-minutes>20</idle-timeout-minutes>

<!-- for deployment on WebSphere, must be mapped to a
WorkManager available in the web application's jndi context.


<websphere-workmanager-jndi-name>java:comp/env/wm/MessagingWorkManager</websphere-workmanager-jndi-name>

-->

</properties>

</channel-definition>



.....

</channels>



then in your WEB-INF\flex\data-management-config.xml

you have channel entry



<default-channels>

<channel ref="my-rtmp"/>

</default-channels>



and your destination

<destination id="notes">

<adapter ref="actionscript"/>

<properties>

<metadata>

<identity property="noteId"/>

</metadata>

</properties>

</destination>



check that your channel entry in data-management-config.xml
corresponds to your channel setup in services-config.xml

thanks for your answer, now my application compiles fine.

however I have an error when I execute it.

do you have an idea why I have this message with IE7 (jrun is
started) ?



thanks

if you use default configs - your
WEB-INF\flex\services-config.xml should contain



<channel-definition id="my-rtmp"
class="mx.messaging.channels.RTMPChannel">

<endpoint uri="rtmp://{server.name}:2037"
class="flex.messaging.endpoints.RTMPEndpoint"/>

<properties>

<idle-timeout-minutes>20</idle-timeout-minutes>

<!-- for deployment on WebSphere, must be mapped to a
WorkManager available in the web application's jndi context.


<websphere-workmanager-jndi-name>java:comp/env/wm/MessagingWorkManager</websphere-workmanager-jndi-name>

-->

</properties>

</channel-definition>



try to change <endpoint uri="rtmp://{server.name}:2037" to
<endpoint uri="rtmp://{server.name}:2038" there

[flex_freddyboy]

Thanks for your answer, in fact in my configuration file, it
was already indicated 2038. it's strange, my code seems to be ok
and configuration files too.



I don't know why code don't work. the applications works fine
on your computer ?



thanks.

[yggdraa]

the message server cant connect to localhost:2038 for some
reason...

so try to change port number or change localhost to your
server ip address to see if it works



all works fine on my computer

[flex_freddyboy]

ok thank you, I'm going to take a look. I keep you
posted.

[flex_freddyboy]

I have found the problem. I have changed the port number to
2037 and now application works. I don't know why.



thanks for your help

[yggdraa]

may be some other application listens to 2038 port

you can find out this by `netstat -an` - and see if there
2038 port is listed



here is a list of ports and registered applications that use
them -

look.
