jboss-deployment-structure.xmlの話です。
よく忘れて見落としちゃうんですよね(´･ω･`)

こんな感じでNoClassDefFoundErrorが出るといつもMavenのpom.xmlを見直して
<scope>provided</scope>
だよねぁ、アレ！？って手が止まることがあるんですが、
そもそも外部ディレクトリに配置するものは
MyApplicationWeb/src/main/webapp/WEB-INF/jboss-deployment-structure.xml
への設定も必要なんですよね。

今回はMySQL JDBC Connectorだったので
<module name="com.mysql" />
を追加します。
Windowsだと外部ディレクトリは
C:\wildfly-10.0.0.Final\modules\system\layers\base\com\mysql\main
ですね。
ちょっとした自戒と備忘録でした。
