Hello Robert,
This is the case, my destination is linked to the custom assembler. In
fact, the way to do that is to create a value object (ie RoomVO) and set
2 variables : id and xmlDoc (as org.w3c.dom.Document).
In my custom assembler, I use an arrayCollection and add into a RoomVO
instance, with an arbitrary id and my xml document.
In the flex side, I have allready a RoomVO value object with id and
xmlDoc (as XML), and all is ok.
regards.

Hi Thierry,
try just configure your destination to use the custom java assembler,
not the hibernate.

Hello group !
I would like to create my own custom assembler to retrieve some data
from database in xml format. I don't know if it's the better way to do
that, but I have some hibernate assemblers called in my application,
and don't want to complexify with other http or rpc services... Tell
me if I'm on the wrong way :)p
So I create an assembler like this, just for tests :
/**
*
*/
package com.neolinkup.app.vo;
import flex.data.assemblers.AbstractAssembler;
import flex.messaging.io.ArrayCollection;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.ParserConfigurationException;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
/**
* @author titouille

*/
public class RoomAssembler extends AbstractAssembler
{
public ArrayCollection fill()
{
String s = "<rooms>" +
"<cinema id='1'
label='cinema 1'>" +
"<room
roomid='1' label='room 1' />" +
"<room
roomid='2' label='room 2' />" +
"</cinema>" +
"</rooms>";
try
{
DocumentBuilderFactory docBuilderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder =
docBuilderFactory.newDocumentBuilder();
ArrayCollection a = new ArrayCollection();
a.add( docBuilder.parse( new InputSource(
new ByteArrayInputStream(
s.getBytes() ) ) ) );
return a;
}
catch( ParserConfigurationException pce )
{
System.out.println( "ERROR -
ParserConfigurationException:
getXmlDocument - " + pce.getMessage() );
return null;
}
catch( SAXException saxe )
{
System.out.println( "ERROR - SAXException:
getXmlDocument - " +
saxe.getMessage() );
return null;
}
catch( IOException ioe )
{
System.out.println( "ERROR - IOException:
getXmlDocument - " +
ioe.getMessage() );
return null;
}
}
}
and my destination :
<destination id="roomvo.hibernate">
<adapter ref="java-dao" />
<properties>
<source>com.neolinkup.app.vo.RoomAssembler</source>
<scope>application</scope>
<metadata>
<identity property="roomid"/>
</metadata>
<network>
<session-timeout>20</session-timeout>
<paging enabled="false"
pageSize="10" />
<throttle-inbound policy="ERROR"
max-frequency="500"/>
<throttle-outbound policy="REPLACE"
max-frequency="500"/>
</network>
<server>
<fill-method>
<name>fill</name>
</fill-method>
</server>
</properties>
</destination>
And I try with a simple mxml application with :
ds = new DataService( "roomvo.hibernate" );
list = new ArrayCollection();
s.addEventListener( DataServiceFaultEvent.FAULT, this._handleFault );
s.addEventListener( DataConflictEvent.CONFLICT,
this._handleConflict );
s.addEventListener(ResultEvent.RESULT, this._handleResult );
s.fill( list );
But Flex return to me an error like this :
ArgumentError: Items must support IManaged. See [Managed] for more
information: object: <rooms>
<cinema id="1" label="cinema 1">
<room roomid="1" label="room 1"/>
<room roomid="2" label="room 2"/>
</cinema>
</rooms> with referencedIds []

If I try to return a dom document instead of an arrayCollection, lcds
return to me a casting error...
Any suggestion about how to get some "read-only" XML data to fill a
tree with complex hierarchical data... I need java to get data from DB
and format it as XML, but don't know the better way to do it... If
anyone has a way or some informations, tutorials, etc... I'm very
interested.
Thanks in advance.
