如何在Netbeans中将现有企业项目从Java EE5升级到Java EE 6(6.9)

Question

该项目有一个EJB模块和一个Web模块.更改服务器很简单,但我也想切换到EJB 3.1,但我相信我需要更改所有类型的配置文件,因为我无法从项目属性窗口中执行此操作.

任何提示或链接做有用的文档将不胜感激.

谢谢!

Answer 1

显然它并不复杂.它通过修改以下文件为我工作:

<project-folder>/nbproject/project.properties 更改以下行:

j2ee.platform=1.5
javac.source=1.5
javac.target=1.5

至

j2ee.platform=1.6
javac.source=1.6
javac.target=1.6

重复相同的:

<project-name>/ <project-name>-ejb/nbproject/project.properties

<project-name>/ <project-name>-war/nbproject/project.properties

在ejb-jar.xml中更改行:

   <ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee" 
         version = "3.0"
         xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd">

至

<ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee" 
         version = "3.1"
         xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd">

接下来,查找persistence.xml并更改此行:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

至

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
