flex.messaging.io.ArrayCollection not found

[Former Community Member]

I have written a Java class that takes an argument of a java
Collection, that consists of my custom Java VOs.

When I call this from Flex 2.0 beta 3 when the class is in my
JRun classpath, everything is fine.

Flex converts the argument to a Collection that Java can
understand.



When I call the same class remotely, I receive an error from
Java.

It seems Flex wraps the ArrayCollection in a
flex.messaging.io.ArrayCollection for remote calls.

Anyone know how to prevent and/or get around this.



My remote object is defined as:

<mx:RemoteObject id="GenSQL_StatusReason"
destination="SecurityManagerRO" showBusyCursor="true">

<mx:method name="genSQL_StatusReason"

result="event.call.resultHandler(event)"

fault="event.call.faultHandler( event )"/>

</mx:RemoteObject>



The Java interface looks like this:

import java.util.Collection;



public String genSQL_StatusReason(LifeCycleStatusVO
statusVO,

ReasonVO reasonVO, Collection Teams, Collection Queues){



etc . . .

You can stop a channel endpoint from converting
java.util.Collection implementations to
mx.collections.ArrayCollection (the ActionScript class
representation that the client sees) by setting the
<serialization> property <legacy-collection> to true:



<channel-definition ...>

...

<properties>

<serialization>

<legacy-collection>true</legacy-collection>

...



However, I'd suggest trying to work with
mx.collection.ArrayCollection and try to solve the issues you're
having. If a class is not found on the server, check that
flex-messaging.jar and flex-messaging-common.are in /WEB-INF/lib.
If you're using RMI, then the remote endpoint would also need these
classes.



If a class is not found on the client then you typically
ensure you have a dependency to that class in your ActionScript so
that it gets compiled into your SWF. For the final release we added
a dependency to ArrayCollection in the channels so that all
applications would have this class available on the client.
