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上尝试它时，它给了我以下错误。

从研究来看，似乎是依赖的问题，它只有接口。

<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>

但没有运气。我也在寻找像j2ee.jar这样的罐子。我可以在JBoss运行时找到一个jboss-ejb-api_3.2_spec-1.0.0.Final-redhat-1.jar。但它并没有在javax.jms上包含任何内容。*。

我还看了课程加载。使用jboss-deployment-structure.xml修补ear文件，内容可以消除双类加载。

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

仍然无法运作。有什么建议吗？

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都被剥离，导致java.lang.ClassFormatError。

您看到这个的原因是因为即使您的dependency说<scope>provided</scope>，此jar的副本也已泄漏到您的应用程序部署中。你需要摆脱它。

完成此操作后，您可以将依赖关系升级到<version>7.0</version>，但没有此问题（这通常只是依赖于它的单元测试的问题）。
