如何在 Netbeans (6.9) 中将现有企业项目从 Java EE5 升级到 Java EE 6 [英] How do I upgrade an existing enterprise project from Java EE5 to Java EE 6 in Netbeans (6.9)

问题描述

该项目有一个 EJB 模块 &一个网络模块.更改服务器很容易，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进行更改.

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).

任何有用的文档的提示或链接将不胜感激.

Any tips or links do useful documentation will be greatly appreciated.

谢谢！

推荐答案

显然没有那么复杂.它通过修改以下文件对我有用:

Apparently it's not that complicated. It worked for me by modifying the following files:

/nbproject/project.properties更改以下几行:

<project-folder>/nbproject/project.properties change the following lines:

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

到

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

重复同样的操作:

/-ejb/nbproject/project.properties

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

/-war/nbproject/project.properties

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

在 ejb-jar.xml 中更改行:

In ejb-jar.xml change the line:

   <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">

到

<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，找到persistence.xml并修改这一行:

Next, find persistence.xml and change this line:

<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">

到

<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">
