我正在开发一个基于J2EE EJB JSF的项目，数据库是MYsql，该项目上周运行良好。但是今天，当我运行它时它无法部署。这里有一些例外：
Initial deploying ECOM to C:\Users\John624\Documents\NetBeansProjects\PromoCoupon\ECOM\dist\gfdeploy\ECOM
Completed initial distribution of ECOM
Initializing...
invalid header field name: Exception Description
C:\Users\John624\Documents\NetBeansProjects\PromoCoupon\ECOM\nbproject\build-impl.xml:307: The module has not been deployed.
See the server log for details.
BUILD FAILED (total time: 5 seconds)

答案 0 :(得分：11)
如以下异常堆栈跟踪所示
Exception Description: Error encountered when building the @NamedQuery [Adresse.maxId] from entity class [class org.eclipse.persistence.internal.jpa.metadata.queries.NamedQueryMetadata].
问题在于：
@NamedQuery(name = "Adresse.maxId", query = "SELECT max(idAdresse) FROM Adresse"),
要解决此问题，请尝试以下方法：
@NamedQuery(name = "Adresse.maxId", query = "SELECT max(a.idAdresse) FROM Adresse a"),
答案 1 :(得分：0)
尝试以下步骤：
答案 2 :(得分：0)
尝试删除adresseManager = new AdresseManager（）;来自你的AdresseMBean课程。
@EJB注入并创建了对象。
然后尝试重新部署项目并在getAdresses方法中放置一个调试断点，以查看adresseManager对象是否为null或是否执行了错误的Sysout。
如果要在启动托管bean时初始化服务，则需要在托管bean内部的自定义公共方法上使用@PostConstruct注释，并在那里编写初始化代码（例如，从db加载实体列表）。
希望它会对你有所帮助。
PS：请原谅我的英语错误，我是法国人。PS2：我之前没有看到它正在运行，所以这可能是部署问题！
