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

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).

任何提示或链接都会提供有用的文档。

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

谢谢！

推荐答案

显然它并不复杂。它通过修改以下文件为我工作：

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

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

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

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

to

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

重复相同的内容：

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

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

< project-name> / < project-name> -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 并更改这一行：

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">
