Camel Example "camel-example-spring-jms" ( http://activemq.apache.org/camel/tutorial-jmsremoting.htmlでも) を実行しようとしています。ただし、「org.apache.camel.spring.Main」クラスを使用して Camel を起動しようとすると、次のエラーが表示されます。
「構成の問題: XML スキーマ名前空間の Spring NamespaceHandler が見つかりません [ http://activemq.apache.org/schema/core]」
[注: Maven コマンド "mvn exec:java -PCamelServer" を使用すると、例を問題なく実行できます]
誰かがこれを引き起こしている可能性のあるものを理解するのを手伝ってもらえますか. 潜在的な解決のヒントも害にはなりません:)
