大家应该知道seam里面自带的messages的那个example吧？我运行这个例子的时候是没问题的，在jboss4.2.2GA的default配置下。
然后我用JBossTools-2.0.0.GA＋eclipse 3.3.1.1建立了一个seam web project, 跟着向导建立的；然后参考seam2.0的reference: http://www.redsaga.com/opendoc/Seam2.0/html/tutorial.html#messages 一步一步地做，然后出问题了：

ParametersName Value None Request AttributesName Value ajaxContext org.ajax4jsf.context.AjaxContextImpl@1ad552c message org.perizone.Messages2.entity.Message@b2fd30 Session AttributesName Value None Application AttributesName Value securityRules org.jboss.seam.drools.RuleBase@10c81a6 可以看到，我的entityBean都被正确地放到request scope里面了，但我的stateful sessionBean却没有，我的sessionBean实现的代码： @Stateful @Name("manager") @Scope(ScopeType.SESSION) public class ManagerBean implements Serializable, Manager { private static final long serialVersionUID = 3540863204015110619L; @In FacesMessages facesMessages; @DataModel private List<Message> messageList; @DataModelSelection @Out(required = false) private Message message; @PersistenceContext(type = PersistenceContextType.EXTENDED) private EntityManager em; @Factory("messageList") @SuppressWarnings("all") public void findMessages() { messageList = em.createQuery("from Message msg order by msg.dateTime desc").getResultList(); } public void select() { if (this.message != null) { this.message.setRead(true); } } public void delete() { if (message != null) { messageList.remove(message); em.remove(message); message = null; } } // add additional action methods @Remove @Destroy public void destroy() { } } 可以说跟例子没什么区别。 这是我的sessionBean的local interface: @Local public interface MessageManager { public void findMessages(); public void select(); public void delete(); public void destroy(); } 这是我的components.xml: <?xml version="1.0" encoding="UTF-8"?> <components xmlns="http://jboss.com/products/seam/components"

把我整晕了，我翻了网上好多文章了，还是没有解决，迫不得已发帖请教，各位大虾初学seam的时候应该也遇到过吧？请指点一二！ |

是不是你用工具生成的的components.xml文件中<core:init jndi-pattern=
这一行的内容与原来的不一样啊！ |

whalm2005 写道 是不是你用工具生成的的components.xml文件中<core:init jndi-pattern=
这一行的内容与原来的不一样啊！ 问题了结了，我又重新建立了一个空白工程，部署它，然后跑到deploy目录下看，发现了“奥秘”：原来我的xxxx-ds.xml文件没有copy到deploy下面.......恍然大悟，本来jbossTools默认是会帮我拷这个文件的，但在部署前的界面里面是和xxxx-ear是分开的，我还以为是别的东西，所以随手就给勾掉了......现在手动把它拷过去就好了...大家以后可别像我这样啊...... 还是谢谢你的回答，你说的这个问题刚开始也出了，我把jndi-pattern=＠jndiPattern改成jndi-pattern＝Messages-ear/\#{ejbName}/local就好了(其实不用改的，jbossTools生成的工程里有一个components.properties,里面写好了jndiPattern=Messages2-ear/\#{ejbName}/local，xml里面用默认的@jndiPattern@来引用就好了)。 |
