Pushing Messages From BlazeDs to Flex (Invoking within Java) -

-

i'm having trouble figuring out how send message via blazeds(on tomcat) flex client. have working send/receive message client, have situation need send message originating in java. thought easier.

methods have tried:

  • messageservice.pushmessagetoclients(msg);

  • serviceadapter.invoke(msg);

    exception: flex.messaging.messageexception: java.lang.nullpointerexception : null

  • messagebroker.routemessagetoservice(msg);

    [blazeds]14:03:35.898 exception when invoking service: (none) message: flex message (flex.messaging.messages.asyncmessage)

services.xml:

<channel-definition id="my-streaming-amf"     class="mx.messaging.channels.streamingamfchannel">     <endpoint url="http://192.168.2.43:8400/testdrive/messagebroker/streamingamf"     class="flex.messaging.endpoints.streamingamfendpoint"/> </channel-definition>

message-config.xml:

<?xml version="1.0" encoding="utf-8"?> 

<adapters>      <adapter-definition id="actionscript" class="flex.messaging.services.messaging.adapters.actionscriptadapter" default="false" />      <adapter-definition id="amfmessageadapter" class="services.amfmessageadapter" default="true" />     <!-- <adapter-definition id="jms" class="flex.messaging.services.messaging.adapters.jmsadapter"/> -->  </adapters>  <default-channels>     <channel ref="my-streaming-amf"/> </default-channels>  <destination id="amfmessageadapterdestination">     <channels>         <channel ref="my-streaming-amf" />     </channels>     <adapter ref="amfmessageadapter" /> </destination>

amfmessageadapter

package services;  import flex.messaging.messages.asyncmessage; import flex.messaging.messages.message; import flex.messaging.services.messageservice; import flex.messaging.services.serviceadapter;  /**  * test service adapter.  great testing when want send object , nothing  * else.  class has stay in main codebase (instead of test) because, when it's used  * needs deployed tomcat.  * @author kevin g  *  */  public class amfmessageadapter extends serviceadapter {      string testmessage = "test_message";      @override     public object invoke(message message) {             asyncmessage newmessage = (asyncmessage) message;         newmessage.setbody(testmessage);         messageservice msgservice = (messageservice)getdestination().getservice();         msgservice.pushmessagetoclients(newmessage, false);         return null;     }  }

any ideas folks?
