以前に jboss アプリケーション サーバーにデプロイしたことがありません。に Java Web アプリケーションをデプロイしようとしたときに、次のエラーが発生しましたopenshift。と を使用SpringしてJPA 2.0います。

じぶんのapplicationContext.xml

<jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/MysqlDS" resource-ref="true" />

じぶんの standalone.xml 

<datasource jndi-name="java:jboss/datasources/MysqlDS" enabled="${mysql.enabled}" use-java-context="true" pool-name="MysqlDS">
                    <connection-url>jdbc:mysql://${env.OPENSHIFT_DB_HOST}:${env.OPENSHIFT_DB_PORT}/${env.OPENSHIFT_APP_NAME}</connection-url>

JBoss が接続なしで永続コンテキストをロードできるように、hibernate.dialect プロパティを設定する必要があります (接続を使用して方言を検出できます)。アプリケーション（あなたの場合はSpring）からの接続を待ちます。

persistence.xml で設定するか、クラスパスのルート ディレクトリに配置された hibernate.properties で設定できます。

プロジェクトの設定はどうですか? プロジェクトは jboss 7.1.0 Final でローカルに実行されますか? JPA 2.0 構成の EntityManagerFactory と hibernate.dialect を定義する persistence.xml ファイルを使用します。META-INF ディレクトリにあります。それが私のプロジェクトでセットアップする方法です。
