java.lang.NoClassDefFoundError Erlang在Jboss 7中对EJB项目有maven依赖关系

Question

我有一个EAR项目链接到War和Ejb项目。

我想补充西河依赖通过POM做EJB项目：

<dependency> 
     <groupId>com.thoughtworks.xstream</groupId> 
     <artifactId>xstream</artifactId> 
     <version>1.4.7</version> 
    </dependency> 

项目编译罚款和EJB的罐子被部署到EAR部署DIR：

但在运行时调用无状态EJB方法时出现此错误： 18：14：49,977 ERROR [stderr]（http - 0.0.0.0-8084-2）引起：java.lang.ClassNotFoundException：com.thoughtworks.xstream.XStream从[Module“deployment.PortalScopeWebEAR.ear.PortalScopeWebEJB-2.27.46.7.jar：main”f ROM服务模块加载程序]

如果我将xstream依赖项添加到WAR项目，我可以调用Xstream类而不会出错。

Ty提前。

我认为问题在于你没有把你的ejb jar依赖放在你的耳朵里的lib文件夹中。如果您正在使用Maven插件的耳朵，请尝试以下

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-ear-plugin</artifactId> 
    <version>2.6</version> 
    <configuration> 
     <!-- Tell Maven we are using Java EE 6 --> 
     <version>6</version> 
     <!-- Use Java EE ear libraries as needed. Java EE ear libraries are 
      in easy way to package any libraries needed in the ear, and automatically 
      have any modules (EJB-JARs and WARs) use them --> 
     <defaultLibBundleDir>lib</defaultLibBundleDir> 
     <modules> 
      <ejbModule> 
       <groupId>xx</groupId> 
       <artifactId>xx</artifactId> 
       <bundleFileName>xx</bundleFileName> 
      </ejbModule> 
      <webModule> 
       <groupId>xx</groupId> 
       <artifactId>xx</artifactId> 
       <contextRoot>xx</contextRoot> 
      </webModule> 
     </modules> 
    </configuration> 
</plugin> 

此外，检查你的劲歌，您要复制由jboss提供的罐子。例如休眠瓶..请确保您使用的<scope>provided</scope>那些样的依赖关系
