Ant EJB会话bean未绑定在JBoss 5的EAR封装中
我有一个动态web项目，我以EAR格式部署在JBoss5上。我使用ant在应用服务器上编译和部署ear文件。若我独立地部署EJB和war客户机，那个么一切都可以工作，但当我尝试在ear中打包时，会话bean并没有绑定。我的EJB代码和clientWeb在同一个项目中，我的项目中并没有独立的EJB模块。我尝试将jar添加到WEB-INF库中的业务接口之外，甚至ear文件的lib目录中，但没有任何效果。我想知道EJBJAR是否不在类路径中，以及如何设置ear文件中模块的顺序 application.xmlAnt EJB会话bean未绑定在JBoss 5的EAR封装中,ant,jboss,ejb,ear,Ant,Jboss,Ejb,Ear,我有一个动态web项目，我以EAR格式部署在JBoss5上。我使用ant在应用服务器上编译和部署ear文件。若我独立地部署EJB和war客户机，那个么一切都可以工作，但当我尝试在ear中打包时，会话bean并没有绑定。我的EJB代码和clientWeb在同一个项目中，我的项目中并没有独立的EJB模块。我尝试将jar添加到WEB-INF库中的业务接口之外，甚至ear文件的lib目录中，但没有任何效果。我想知道EJBJAR是否不在类路径中，以及如何设置ear文件中模块的顺序 application.

当我们从EJB模块中打包一个EAR文件时，客户机的查找方法会略有变化。我们总是可以在控制台中检查注入应该参考的路径
@EJB(mappedName="YOUR_EAR_NAME/ManageStudentSessionBean/local")
您是否尝试过将@Statelessname=manageStudentSessionBean添加到EJB模块，而不仅仅是@Stateless，并且在servlet中，在条目private ManageStudentSessionBeanLocal ManageStudentSessionBeanLocal=null上方使用注释@EJBname=ManageStudentSessionBeanLocal；谢谢你的帮助，但遗憾的是它没有起作用。ejb模块是否进入类路径？你知道，当我试图通过在war的类路径中添加ejb模块来独立部署war和ejb模块时，它就可以工作了。我不相信它需要进入类路径。您是否在WAR的web-INF文件夹中有一个web.xml文件，正如在web模块中进行注入的链接文章所述，您的web.xml应该使用2.5版本的web应用程序xsd-您可以尝试使用重要部分中显示的xml创建该文件吗？@JGlass我在问题中添加了web.xml结构，是的，它使用2.5版本。我认为客户端应该在类路径中有ejb模块，以便在web.xml上部署和编译。我相信有了JBoss类加载器，EJB模块已经在类路径中了——您是指将其作为类补丁条目添加到web应用META-INF/MANIFEST.MF文件中吗？我的所有项目都没有这个清单，但其中有许多项目正在升级到JBoss7。部署应用程序时，server.log文件中会显示哪些输出？
