I am having a problem with consuming messages using WebLogic 10.2's JMS to
send messages to my Flex client.
The error I am getting is the following:
*ArgumentError: Error #2173: Unable to read object in stream. The class
weblogic.jndi.internal.WLEventContextImpl does not implement
flash.utils.IExternalizable but is aliased to an externalizable class.*
I am essentially customizing the trader desktop application to work in a
weblogic cluster ( as a POC / load testing tool ).
In my messaging-config.xml I have the following destination configured:
<destination id="LCDSLoadTest">
<properties>
<network>
<session-timeout>0</session-timeout>
</network>
<server>
<max-cache-size>1000</max-cache-size>
<message-time-to-live>0</message-time-to-live>
<durable>false</durable>
<allow-subtopics>true</allow-subtopics>
<subtopic-separator>.</subtopic-separator>
</server>
<jms>
<destination-type>topic</destination-type>
<message-type>javax.jms.TextMessage</message-type>
<connection-factory>weblogic.jms.ConnectionFactory</connection-factory>
<destination-jndi-name>LCDSLoadTestTopic</destination-jndi-name>
<delivery-mode>NON_PERSISTENT</delivery-mode>
<message-priority>DEFAULT_PRIORITY</message-priority>
<acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
<transacted-sessions>false</transacted-sessions>
</jms>
</properties>
<channels>
<channel ref="my-rtmp"/>
<channel ref="my-nio-amf-poll"/>
<channel ref="my-nio-amf-longpoll"/>
<channel ref="my-nio-amf-stream"/>
<channel ref="my-nio-http-poll"/>
<channel ref="my-nio-http-longpoll"/>
<channel ref="my-nio-http-stream"/>
<channel ref="my-polling-amf"/>
<channel ref="my-streaming-amf"/>
</channels>
<adapter ref="jms" />
</destination>
My JMS topic is configured in Weblogic 10.2 as follows:
<?xml version='1.0' encoding='UTF-8'?>
<weblogic-jms xmlns="http://www.bea.com/ns/weblogic/90"; xmlns:sec="
http://www.bea.com/ns/weblogic/90/security"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"; xmlns:wls="
http://www.bea.com/ns/weblogic/90/security/wls"; xsi:schemaLocation="
http://www.bea.com/ns/weblogic/920 http://www.bea.com/ns/weblogic/920.xsd";>
<topic name="LCDSLoadTestTopic">
<jndi-name>LCDSLoadTestTopic</jndi-name>
</topic>
</weblogic-jms>
Does anybody have any idea what I might be missing, and why the object is
not able to be deserialized by Flex? It works fine using the messaging built
into LCDS, but that doesn't work well in a clustered environment, so I need
to use the appserver's JMS capabilities.
Thanks in advance!
Nick
