publishweborb

Error while publishing message from .NET (WebORB)

I am trying to publish message (C# console app):

var client = new WeborbClient("http://localhost:57433/weborb.aspx", "MyDestination");
client.Publish("test message");

...and getting NullReferenceException:

at Weborb.Writer.ObjectWriter.write(Object obj, IProtocolFormatter writer) at Weborb.Writer.ObjectReferenceWriter.write(Object obj, IProtocolFormatter formatter) at Weborb.Writer.ArrayWriter.write(Object obj, IProtocolFormatter writer) at Weborb.Writer.ArrayReferenceWriter.write(Object obj, IProtocolFormatter formatter) at Weborb.Writer.MessageWriter.writeObject(Object obj, IProtocolFormatter formatter) at Weborb.Writer.AMFBodyWriter.write(Object obj, IProtocolFormatter writer) at Weborb.Writer.MessageWriter.writeObject(Object obj, IProtocolFormatter formatter) at Weborb.Util.Cache.Cache.WriteAndSave(Object obj, IProtocolFormatter formatter) at Weborb.Writer.AMFMessageWriter.write(Object obj, IProtocolFormatter writer) at Weborb.Writer.MessageWriter.writeObject(Object obj, IProtocolFormatter formatter) at Weborb.Util.AMFSerializer.SerializeToBytes(Object obj, Int32 serializationType) at Weborb.Util.AMFSerializer.SerializeToBytes(Object obj) at Weborb.Client.HttpEngine.CreateRequest(V3Message v3Msg, Dictionary2 headers) at Weborb.Client.HttpEngine.CreateRequest(V3Message v3Msg) at Weborb.Client.HttpEngine.SendRequest[T](V3Message v3Msg, Responder1 responder, Boolean isSubscription) at Weborb.Client.Engine.SendRequest[T](V3Message v3Msg, Responder1 responder) at Weborb.Client.WeborbClient.Publish(Object message, Dictionary2 headers, String subtopic, PublishingResponder responder) at Weborb.Client.WeborbClient.Publish(Object message, Dictionary`2 headers)

Publishing to the same destination works successfully from Flex app:

<mx:ChannelSet id="channelSet">
    <mx:AMFChannel url="http://localhost:57433/weborb.aspx"/>     
</mx:ChannelSet>

<mx:Producer id="producer"
         channelSet="{channelSet}"
     destination="MyDestination" />

// ...
var message:AsyncMessage = new AsyncMessage( "weborb messaging is cool" );
producer.send( message );
Solution

  • The solution is to deploy weborb.config into the same folder where your executable runs from.
