I've been trying for the last few days to get RemoteObject to work,
but with little luck. I've searched this site, and have tried to
implement the examples found in "developing rich clients with
macromedia FLEX". To make matters more confusing, I've also tried to
implement the command/control/delegate patterns that the above book
advocates.
Basically, I think the problem is that I'm not "seeing" the Java
classes I've created. Below are code snippets of (what I think) are
the relevant files.
### My Java classes ###
{TOMCAT-HOME}\webapps\flex\WEB-
INF\classes\com\foo\test\business\SiteMaintenanceDelegate.class
package com.foo.test.business;
import com.foo.test.vo.SiteKeywordVO;
public class SiteMaintenanceDelegate {
public SiteMaintenanceDelegate() {
}
public SiteKeywordVO reviewKeywords() {
SiteKeywordVO keywords = new SiteKeywordVO();
return keywords;
}
}
{TOMCAT-HOME}\webapps\flex\WEB-
INF\classes\com\foo\test\vo\SiteKeywordVO.class
package com.foo.test.vo;
import java.io.Serializable;
public class SiteKeywordVO implements Serializable {
public String[] keywords;
public void SiteKeywordVO() {
String[] keywords = {"first agr", "second agr", "third agr"};
}
}
### My RO definition ###
{TOMCAT-HOME}\webapps\flex\services\Services.mxml
<mx:RemoteObject id="siteDataServices"
source="com.foo.test.business.SiteMaintenanceDelegate"
result="event.call.resultHandler(event)"
fault="event.call.faultHandler(event)"
showBusyCursor="true">
<mx:method name="reviewKeywords"/>
</mx:RemoteObject>
### My ActionScript VO ###
{TOMCAT-HOME}\webapps\flex\sdm\com\foo\test\vo\SiteKeywordVO.as
class com.foo.test.vo.SiteKeywordVO {
public var keywords:Array;
public var _remoteClass;
public function SiteKeywordVO() {
_remoteClass="com.foo.test.vo.SiteKeywordVO";
}
}
### My testing mxml file ###
{TOMCAT-HOME}\webapps\flex\sdm\sdmUnitTest.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";
xmlns:sdm="sdm.*"
xmlns:services="services.*"
<sdm:SiteDataMaint/>
<services:Services id="myServices"/>
</mx:Application>
### My SiteDataMaint component ###
{TOMCAT-HOME}\webapps\flex\sdm\SiteDataMaint.mxml
... //just the script part
<mx:Script>
<![CDATA[
import sdm.business.*;
import sdm.commands.*;
import sdm.control.*;
import com.foo.test.vo.*;
import mx.controls.Alert;
public function initApp() {
var controller = new SDMController;
}
]]>
</mx:Script>
...
The SDMController class seems to be working correctly.
### My Delegate class ###
{TOMCAT-HOME}\webapps\flex\sdm\business\SDMDelegate.as
... //just the constructor
public function SDMDelegate(responder:Responder) {
this.service =
mx.core.Application.application.myServices.siteDataServices;
Dumper.dump(service);
this.responder = responder;
}
I think this is where the problem is. When I dump 'service' (via
Flex Trace Panel), I get 'undefined'.
I really have no idea where to go from here. I've tried turning on
all debug stuff, used NetConnectionDebugger, use Flex Trace Panel...
nothing on all accounts.
Thanks for any suggestions you may have!
