java - 部署 Java 企业应用程序失败

Question

使用 Netbeans，我创建了带有 ejb 模块和 war 模块的 Java 企业应用程序。我对 war 模块做了一些更改，一切正常。但现在我试图调用 ejb 模块中定义的远程 ejb。我已经遵循了本教程 https://netbeans.org/kb/docs/javaee/entappclient.html 。现在，当我尝试在我的应用程序服务器(JBoss AS7)中部署ear文件时，我收到以下错误:

{"JBAS014653: Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"JBAS014671: Failed services" => {"jboss.deployment.subunit.\"events.ear\".\"events-ejb.jar\".POST_MODULE" => "org.jboss.msc.service.StartException in service jboss.deployment.subunit.\"events.ear\".\"events-ejb.jar\".POST_MODULE: Failed to process phase POST_MODULE of subdeployment \"events-ejb.jar\" of deployment \"events.ear\""}}}} /Users/Luis/NetBeansProjects/events/nbproject/build-impl.xml:307: The module has not been deployed.

为什么会发生这种情况？

我对netbeans了解不多。我建议使用 GlassFish，就像上面链接的教程一样。如果您确实想使用 JBoss AS 7，那么您需要开始阅读文档。默认情况下，由于适当的隔离类加载器，JBoss 中的模块无法看到彼此。我的猜测是你只需要关闭它或正确打包你的代码。文档在这里:
