Tomcat、Atomikos、ActiveMQ、および MySql を使用してトランザクションを機能させようとしています。次の例に従ってください: Tomcat 7 の Atomikos 3.5.2との統合 およびTomcat 7.0.27 の Atomikos 3.7.1との統合 成功しませんでした...
ERROR: com.atomikos.icatch.jta.UserTransactionManager cannot be cast to javax.transaction.TransactionManager
java.lang.ClassCastException: com.atomikos.icatch.jta.UserTransactionManager cannot be cast to javax.transaction.TransactionManager
使用:
- トムキャット 7.0.29
- アトミコス 3.7.1
- アクティブMQ 5.8.0
- MySQL 5.5.31

私は何を間違っていますか？
編集：
$TOMCAT_HOME/lib から activemq-all-5.8.0.jar を削除した後、元のエラーを回避できましたが、次のようになりました。

Caused by: com.atomikos.jms.AtomikosTransactionRequiredJMSException: The JMS session you are using requires a JTA transaction context for the calling thread and none was found.
Please correct your code to do one of the following:
1. start a JTA transaction if you want your JMS operations to be subject to JTA commit/rollback, or
2. increase the maxPoolSize of the AtomikosConnectionFactoryBean to avoid transaction timeout while waiting for a connection, or
3. create a non-transacted session and do session acknowledgment yourself, or
4. set localTransactionMode to true so connection-level commit/rollback are enabled.
