Java から実行中の ActiveMQ サーブレット (Weblogic 12 上) に接続しようとしていますが、次の例外が発生していますconn.start();:

javax.jms.JMSException: Could not post command: ConnectionInfo {commandId = 1, responseRequired = true, connectionId = ID:lmdesetup-jab-38449-1378221016985-2:1, clientId = ID:lmdesetup-jab-38449-1378221016985-1:1, clientIp = null, userName = null, password = *****, brokerPath = null, brokerMasterConnector = false, manageable = true, clientMaster = true, faultTolerant = false, failoverReconnect = false} due to: java.io.IOException: Failed to post command: ConnectionInfo {commandId = 1, responseRequired = true, connectionId = ID:lmdesetup-jab-38449-1378221016985-2:1, clientId = ID:lmdesetup-jab-38449-1378221016985-1:1, clientIp = null, userName = null, password = *****, brokerPath = null, brokerMasterConnector = false, manageable = true, clientMaster = true, faultTolerant = false, failoverReconnect = false} as response was: HTTP/1.1 500 Internal Server Error [Connection: close, Date: Tue, 03 Sep 2013 15:11:02 GMT, Content-Length: 3092, Content-Type: text/html; charset=UTF-8, X-Powered-By: Servlet/3.0 JSP/2.2]

コードは次のとおりです。

QueueConnectionFactory factory = new ActiveMQConnectionFactory("http://localhost:8888/myApp/amq");
Connection conn = factory.createConnection();
conn.start();

(コードは次の例に基づいています: http://activemq.apache.org/hello-world.html )

js クライアントを使用してメッセージを送受信できるため、ActiveMQ ブローカーと AjaxServlet は問題ないと確信しています。

サーブレットは web.xml で次のように定義されています。

<context-param>
    <param-name>org.apache.activemq.brokerURL</param-name>
    <param-value>vm://localhost</param-value>
</context-param>
<context-param>
    <param-name>org.apache.activemq.embeddedBroker</param-name>
    <param-value>true</param-value>
</context-param>

同じ問題を抱えている人を見つけましたが、解決策はありません: http://blog.gmane.org/gmane.comp.java.activemq.user/month=20090501

Weblogic の例外は次のとおりです。
