Maybe some kind of archetype exist for JBoss 5.x.x deployed project? 回答1: Based on maven central I think you need the following: <dependency>

问题 I want to know the differences/similarities between Hibernate and simple persistence in Java EE 5? I'm not clear if Hibernate implements Java EE 5 persistence implementation or if it is a totally different approach to data representation over back-end systems. I'm confused about Hibernate and its relation with the concepts about java persistence given in the Java EE 5 tutorial... could you clarify the role of Hibernate in the context of Entities and EJBs? Also, I want to know other approaches

问题 The project has an EJB module & a web module. Changing the server is easy, but I'd like to switch to EJB 3.1 also but I believe I need to change all kind of configuration files since I can't do it from the project properties window(s). Any tips or links do useful documentation will be greatly appreciated. Thank you! 回答1: Apparently it's not that complicated. It worked for me by modifying the following files: <project-folder> /nbproject/project.properties change the following lines: j2ee

问题 I have a confusion regarding the structure of the web.xml for the servlet mapping, I don't have any problem by executing it but I am trying to figure it how why we have such a pattern in the deployment descriptor. <web-app> <servlet> <servlet-name>Servlet1</servlet-name> <servlet-path>foo.Servlet</servlet-path> </servlet> <servlet-mapping> <servlet-name>Servlet1</servlet-name> <url-pattern>/enroll</url-pattern> </servlet-mapping> </web-app> Now as far as my understanding whenever a request is

问题 I'm working in a Java EE Environment in which each application is in a war file of its own. In the WEB-INF/lib of each application war file there is a common jar that is shared by all applications. This common jar contains several Singletons which are accessed from many points in the code. Because of the war-file boundaries each application has its own instances of the Singletons. Which is how we operate today, since we want to configure some of the singletons differently in each application.

问题 In my JSF project workspace, I have a Java project A and a Weblogic EJB project B that uses the Java project. On generating the EAR I can see that the jar for Project A and B are there in the EAR as well as that of other projects in the workspace. However, on trying to access class from A in B i am getting a class not found exception. The Ejb Project B has the managedbean/dao/ejb/delegate and at this point the EJB is not getting called at all. The managedbean is instantiated and from another

问题 we have a WAR packaged web application which works on a development machine. It consists of Java EE 5 + Seam 2.2.1 + Hibernate 3.3.1. It uses an Oracle 10g XE database and runs on the latest Tomcat 6 using JDK 1.6.0_24. The system is a 64bit Windows 7 Pro and uses Firefox 6. Now, we tried to migrate the application to Oracle WebLogic 10.3.5. We followed the Seam manual for specifying the datasource, deploying the JSF lib and configuring the necessary xml-Files. In parallel to that, we
