RPC Fault

[this_sonix]

Hi everyone,

i developed a small application which worked fine in the
middle of June.

When I startet my app in July, it didn't work anymore and the
following Error occurs:



[FaultEvent fault=[RPC Fault faultString="An unknown
exception occurred while creating an instance of type
'adg.frontend.Messefrontend'."
faultCode="Server.ResourceUnavailable" faultDetail="null"]
messageId="224E43C5-591E-B78D-4558-04D90D1AD5D3" type="fault"
bubbles=false cancelable=true eventPhase=2]



I'm using Flex Beta 3 with Tomcat 5.5 and J2SE 5 SDK 7

After days of searching, I don't know where the fault is.

I tried the, for my config tweaked, configuration of the
example files (samples.war, examples are working).

Without any effect.



My Configuration:



flex-remoting-service.xml:

...

<destination id="Messefrontend">

<properties>

<source>adg.frontend.Messefrontend</source>

</properties>

<adapter ref="java-object" />

</destination>



Messe.MXML:

<mx:RemoteObject id="MesseFrontend"
destination="Messefrontend" result="resultHandler(event.result)"

fault="faultHandler(event)" >

<mx:method name="gewinnCodeEingabe"
concurrency="multiple" />

<mx:method name="getConfirmData"
concurrency="single"/>

</mx:RemoteObject>



File System:

Tomcat
5.5\webapps\flex\WEB-INF\classes\adg\frontend\Messefrontend.class

Tomcat
5.5\webapps\flex\WEB-INF\src\adg\frontend\Messefrontend.java

Tomcat 5.5\webapps\flex\Messe\Messe.mxml



Java Files are working if I start them with a main Method in
Eclipse.



Hope someone can help me.

Thanks a lot.

Couple of things.



1) it would be helpful if you had a debug trace going and
provide that as well.

2) you may need to specify and endpoint for you remote object
something like /flex/messagebroker/amf. If you are compiling your
objects and then pushing them to the server, for some reason, flex
does not get your channels defined in your configuration
files.

Did you restart the server each time you changed the
configuration files or touched java code and recompiled it?



Do you have a public, no args constructor on the classes
serving as RemoteObject destination sources?



Are you using any JDK 1.5 specific code in your classes such
as enums? If so, can you try removing anything 1.5 specific and
recompiling to try and work out what the offending code is?



Can you try to instantiate the class using a JSP page?
