deployment - JBOss 无法找到类 : Not installing optional component "X" due to exception: java. lang.ClassNotFoundException

Question

我正在尝试使用 Ant 将 EAR 文件部署到我的 JBoss。我正在使用 JBoss 7.1。
我已经在那里进行了一些 war (使用相同的部署过程)，但是这个 EAR 包含有关我需要工作的框架的数据。这个框架特别使用了一个 JAR (index-app)，我已经将它包含在它的 lib 文件夹中。

我的 EAR build.xml 中的这段剪辑显示了它如何从其 lib 文件夹中读取 JAR(所有子文件夹都存在):

   <copy todir="${build.home}" flatten="true" includeemptydirs="false">
        <fileset dir="${lib.home}">             
            <include name="index/**/*.jar" />
            <include name="crawler/**/*.jar" />
            <include name="poi/**/*.jar" />
            <include name="*.jar" />
            <exclude name="local/**" />
        </fileset>
    </copy>

当我部署 EAR 时，编译没有问题，只有实际部署在我的日志中生成:

我仔细检查了包含类 SPCCentralServlet 的 JAR 文件存在，它就在生成的 EAR 文件内的 JAR 中，但不知何故 JBoss 找不到它。

有没有人有任何解释或想法？

Answer 1

您需要指定包含类 com.t1c.modules.index.servlets.SPCCentralServlet 的 jar在其中之一:
1. MANIFEST.MF为 war
2.作为jboss模块
3. 作为 jboss-deployment-structure.xml 中的依赖项
