无法解析 Jboss 中的数据源依赖关系

Question

我正在尝试通过 Eclipse 在 JBoss 服务器上部署 JEE Web 应用程序，但我无法解决与数据源相关的依赖性错误。奇怪的是当我开始部署控制台时显示此消息

JBAS014776:    Newly corrected services:
      service jboss.naming.context.java.jboss.datasources.AssetTrackerDS (no longer required)

但是部署失败并出现此错误。

ERROR [org.jboss.as.server] (DeploymentScanner-threads - 2) JBAS015870: Deploy of deployment "AssetTracker.war" was rolled back with the following failure message: {"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.persistenceunit.\"AssetTracker.war#AssetTracker\" is missing [jboss.naming.context.java.jboss.datasources.AssetTrackerDS]"]}

JBoss 服务器已正确配置数据库，连接测试显示正确结果。

我正在使用 JBoss EAP 6.2 和 Eclipse Neon。

您有一个拼写错误：

 <datasource jta="true" jndi-name="java:jboss/datasource/AssetTrackerDS"

对比

<jta-data-source>java:jboss/datasources/AssetTrackerDS</jta-data-source>
