Import javax.ejb.Schedule cannot be resolved

阅读更多关于 Import javax.ejb.Schedule cannot be resolved

问题 I have a problem, eclipse say that it cannot found javax.ejb.Schedule (or Schedules) but no problem with other class like javax.ejb.MessageDriven. I work on a very big application that I don't really know. So my question is how to resolve this? Or a way to look for? 回答1: JBoos 4 is a JEE5 compliant Server, hence JEE6 features are not available. 来源： https://stackoverflow.com/questions/24448063/import-javax-ejb-schedule-cannot-be-resolved

Spring详解（一）------概述

阅读更多关于 Spring详解（一）------概述

　　本系列教程我们将对 Spring 进行详解的介绍，相信你在看完后一定能够有所收获。 1、什么是 Spring ? 　　Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。框架的主要优势之一就是其分层架构，分层架构允许使用者选择使用哪一个组件，同时为 J2EE 应用程序开发提供集成的框架。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。Spring的核心是控制反转（IoC）和面向切面（AOP）。　　简单来说，Spring是一个分层的JavaSE/EE full-stack(一站式) 轻量级开源框架。 2、Spring 起源　　Rod Johnson 在2002年编著的《Expert one on one J2EE design and development》一书中，对Java EE 系统框架臃肿、低效、脱离现实的种种现状提出了质疑，并积极寻求探索革新Spring Logo之道

问题 I'm trying to connect a Weblogic (10.3) MDB to a Tibco EMS JMS queue. I've read from the queue using a simple Java/Spring JNDI connection so I know the foreign JNDI lookup names are valid. My WL foreign server details: JNDI Initial Context Factory: com.tibco.tibjms.naming.TibjmsInitialContextFactory JNDI Connection URL: tcp://ems-dit-am-uat-1.app.xxx.net:30055 JNDI Properties: java.naming.factory.initial=com.tibco.tibjms.naming.TibjmsInitialContextFactory java.naming.provider.url=tcp://ems

Relationship between EJB 3.0 and JPA?

阅读更多关于 Relationship between EJB 3.0 and JPA?

问题 That may seem obvious but I've seen contradictory statements: Is JPA part of EJB 3.0? I'm no specialist and it's quite confusing for me. If so, JPA manipulates Entity Beans? These entity beans being the interface between the persistence layer and the business layer implementing the logic with stateless beans? The underlying question for me is how to implement a "search for user based on various criteria" function, where the "search" request -its string representation- should be built? I mean,

问题 I am executing the following lines: String queString = "some query string" Query q1 = em.createNativeQuery(queString, T03CallsLog.class); T03CallsLog newCall; newCall = (T03CallsLog) q1.getSingleResult(); //this line cause the exception after the first time weird situation. if I only execute it with one instance it works fine, but if I do it parallel with more then one instance(mdb's) then the first one is executed without any exceptions, and all the rest get this error: 10:04:50,750 ERROR

EJB可以说像是一个Web Service，但也不完全是，比如EJB将编写好的业务组件放置在EJB容器上，然后提供接口给客户端访问；但是功能不仅限如此，EJB标准中提供了很多规范等，而这些规范只有在EJB容器才能正常运行。 EJB重量级框架 2. Spring容器取代了原有的EJB容器，因此以Spring框架为核心的应用无须EJB容器支持，可以在Web容器中运行。 Spring容器管理的不再是复杂的EJB组件，而是POJO（Plain Old Java
