java - jboss 无法定义类 javax.jms.JMSException

Question

我是 JBoss 的新手。我有一个 Ear 文件在 WAS 上工作正常。但是当我在 JBoss EAP 7.1 上尝试时，它给出了以下错误。

14:15:18,640 WARN  [org.jboss.modules] (MSC service thread 1-6) Failed to define class javax.jms.JMSException in Module "deployment.xxx.ear.yyy.war:mai

从研究来看，似乎是依赖问题，只有接口(interface)。

<dependency>
  <groupId>javax</groupId>
   <artifactId>javaee-api</artifactId>
   <version>6.0</version>
   <scope>provided</scope>
</dependency>

所以我改为

  <dependency>
    <groupId>org.apache.openejb</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0-5</version>
  </dependency>

但运气不佳。我也在寻找像j2ee.jar这样的jar。我可以在 JBoss 运行时下找到一个 jboss-ejb-api_3.2_spec-1.0.0.Final-redhat-1.jar 。但它不包含 javax.jms.* 上的任何内容。

我还查看了类加载。使用 jboss-deployment-struction.xml 修补了ear文件，其中包含消除双重类加载的内容。

<jboss-deployment-structure> 
    <ear-subdeployments-isolated>true</ear-subdeployments-isolated>    
</jboss-deployment-structure>

还是不行。有什么建议吗？

那个javax.javaee-api.6.0 Maven 依赖项有一个 well documented问题 - 它所需的任何实现类的字节代码已被剥离，导致 java.lang.ClassFormatError .

您看到此情况的原因是因为即使您的 dependency说<scope>provided</scope> ，此 jar 的副本已泄漏到您的应用程序部署中的某处。你需要摆脱它。

完成此操作后，您可以将依赖项升级到 <version>7.0</version>它没有这个问题(这通常只是依赖它的单元测试的问题)。
