FDS can't find my destination.... how to trouble shoot?

[kedward]

Hello,



I am using the adobe DaoFlex to generate a flex application.
Seemed to go well, but when I try to run the application it throws
this error as soon as it trys to "fill" the grid:



"No destination 'Employee' exists in service
flex.data.DataService"



HOW DO I TROUBLE SHOOT? What Can I check?



1) I looked in the application WEB-INF/flex directory



C:\bea\user_projects\applications\theriabook\WEB-INF\flex\data-management-config.xml



and the destination employee is there!

[kedward]

I have tried the "contacts" tutorial also, but get the same
problem. I have the WEB-INF/flex/data-management-config.xml file
with the contact destination....but still the problem!:



MessagingError message='Unknown destination 'contact' for
service with id 'data-service'.']

Hi,



Try importing mx.messaging.config.ServerConfig in your app
and then trace(ServerConfig.xml.toXMLString()).



This is the FDS configuration data that gets injected into a
swf then you compile using the -services option. If this proprety
is empty or does not contain the 'Employee' destination you'll need
to recompile and make sure that you reference your
services.config.xml file using the -services option.



Best,

Seth

Hi Kedward,



Did you fix your problem? I have tried this sample as well
and got the exact error as you.



I did try the way that Seth suggested. It has something and
seems to miss
<source>com.theriabook.datasource.EmployeeAssembler</source>

<scope>application</scope> properties. But when
I check the data-mamangement-config.xml in WEB-INF, it does include
those. I am not sure which services.config.xml and
data-mamangement-config.xml that JRun really reload.

[seth_hodgson]

Hi Michael,



The config info that is injected into the swf and accessible
via ServerConfig.xml is a subset of the total configuration on the
server. The client doesn't need to know the assembler source class
or scope for the destination so those elements are not injected
into the swf.



services.config.xml in my previous post was a typo; it should
be services-config.xml. This config file references the other
service specific config files you're using (e.g.
data-mamangement-config.xml).



Assuming that the destination you're trying to contact is
defined on the client in ServerConfig.xml and the server is running
and also has this destination defined things should work. What is
the specific error you are seeing?



Best,

Seth

[michael6-G7BreH]

Hi Seth,



Thank you for your reply. After I launch the main.xmal and
then click the Fill button, the Message column shows that "No
destination 'Employee' exists in service flex.data.DataService". I
also notice that there are some errors when I start the JRun with
Integrated Flex Server. The bellow is the message copy from the
JRun.

When you try Seth's troubleshooting technique, do you see any
Employee destination listed among the destinations?



As for the server startup, it looks like JRun didn't close
down successfully. Open up the Windows Task Manager. Find the
jrun.exe process (processes) and terminate them. After that, start
up your server again. I don't believe the errors you see are
related to the server startup errors but it's nice to eliminate
this possibility.

[michael6-G7BreH]

Thanks for the reply. I tried the Seth's troubleshooting
technique, and the Employee destination was there. The following is
the output in the Console of Eclipse with
trace(ServerConfig.xml.toXMLString()).

I also terminate the jrun.exe process (processes) and even
restart the machine. But I still see the same errors when I start
JRun or when I click Fill button.

Thanks.

[seth_hodgson]

Hi Michael,



This is the important piece of info in your server startup
stack trace:



Exception in thread "RTMP-Server"
flex.messaging.endpoints.rtmp.RTMPException: T

he RTMP server has encountered a fatal exception starting up:
Address already in

use: bind



RTMP Endpoints start up an internal socket server that binds
to the port specified in the channel-definition endpoint URI.
Unlike HTTP traffic which is all managed by the servlet container
and handed off to your web app(s), RTMP traffic must be handled
directly by FDS. Only a single process can bind to and service
network traffic on any given port so you need to take a look at the
RTMP channel definitions for all FDS apps you've deployed to your
server and make sure they're using unique port values in their
endpoint URIs. Once you've resolved this port collision the server
should start up and run without issue.



HTH,

Seth

[michael6-G7BreH]

Hi Seth,



Thank you for your reply. I found that the
services-config.xml files in flex\WEB-INF\flex and
theriabook\WEB-INF\flex used the same port number 2038
(<endpoint uri="rtmp://{server.name}:2038"
class="flex.messaging.endpoints.RTMPEndpoint"/> ), therefore, I
changed the endpoint uri port number to 2039 for the file
services-config.xml in the theriabook\WEB-INF\flex.

When I start JRun again, the exception



Exception in thread "RTMP-Server"
flex.messaging.endpoints.rtmp.RTMPException: T

he RTMP server has encountered a fatal exception starting up:

use: bind



is not there anymore. But the error

remains there. Strange enough, when I look at the endpoint
uri for my-rtmp in the Console panel output by the trace, it
remains as 2038 (output is: <channel id="my-rtmp"
type="mx.messaging.channels.RTMPChannel">

<endpoint uri="rtmp://{server.name}:2038"/>

<properties/>

</channel> ),

though I have already changed it to 2039. Any ideas?



Thanks.

Michael

[seth_hodgson]

Hi Michael,



For your last question, I think you probably need to
recompile your swf to pick up the changes you made to the config.



For the ClassCastException, could you provide more of that
stack trace?

Seth

The following is the stack trace got after I click Fill
button. Also the error message in the Message column becomes
"Unable to invoke a fill operation on destination 'Employee' due to
the following error: class
com.theriabook.daoflex.DAOException:javax.naming.NameNotFoundException:
No such binding: jdbc."



Best regards,

Michael

Hi Michael,



That first exception looks like a JRun issue and perhaps the
JSPServlet definition in the "Employee Flex Data Services" web
app's web.xml file is incorrect.



I don't know anything about FlexDAO but that second stack
trace looks like their DAO is expecting certain datasources to be
defined in your app server.



Best,

Seth

Hi,



I have met the same problem, following the tuto on this page
:


http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/js/html/wwhelp.htm?href=00000138.html
> Getting Started with Flex 2 > Lessons > Use the Data
Management Service



We followed exactly the lesson and we got the error "No
destination 'Anything' exists in service flex.data.DataService"

Actually our problem came from the project creation, to
succed the lesson, the location for the flex data service serveur
must be defined like that :

Root folders : C:\fds2\jrun4\servers\default\samples

Root URL :
http://localhost:8700/samples/



If you use the default folders all is not at the same level
and that trigger the 'No destination' error.





PS : if you want to do the tuto, don't forget to read the
additionnal information provided by a flex develloper here :
Getting Started with Flex 2 > Lessons > Use the Data
Management Service > Build a distributed application with the
Java adapter > View the samples.contact.Contact class

[Anatole_Tartako]

Flex requires destination defined and referenced via chain
starting at compilation flex-config.xml before you compile
application. Simpliest way to verify that flex compiled your
destination into the client application is to use
-keep-generated_actionscript compiler switch and check destinations
within generated/...FlexInit...as

Thank you,

Anatole
