问题描述

我是Maven的新手，也正在学习它.我在eclipse中有两个项目，一个是包含UI内容的零售产品，另一个是ejb项目retailservice.我为这两个项目分别编写了pom文件，并且能够生成war和jar文件.我要做的是.

I am new to Maven and also learning it. I have two projects in eclipse one is retailproducts which contains UI stuff and other project is ejb project retailservice. I written separate pom files for both the projects and able to generate war and jar files. What i have to do is.

a)我必须在war文件中配置jar文件，因为jar文件包含webappliction所需的ejb内容
b)创建war文件后，我必须创建ear文件，该文件将把war文件转为jar文件.

a) I have to configure jar file in war file as jar file contains ejb stuff which is required by webappliction
b) after creating war file i have to create ear file which will have war file in turn jar file.

我该怎么做.

我在这里同时提供了两个pom.xml.

I am providing both the pom.xmls here.

推荐答案

在构建同时包含WAR和EJB模块的Java EE 5.0应用程序时，通常会有3个Maven模块定义:

When building Java EE 5.0 application containing both WAR and EJB modules you usually have 3 Maven modules that define:

  1. Web应用程序
  2. EJB
  3. EAR

您有前两个，但没有EAR模块.它应该看起来像这样:

You have first two but don't have EAR module. It should look something like this:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>Retail</groupId>
    <artifactId>RetailEAR</artifactId>
    <packaging>ear</packaging>
    <version>0.0.1-SNAPSHOT</version>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-ear-plugin</artifactId>
                <version>2.8</version>
                <configuration>
                    <defaultLibBundleDir>lib</defaultLibBundleDir>
                    <skinnyWars>true</skinnyWars>
                    <version>5</version>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>RetailService</groupId>
            <artifactId>RetailService</artifactId>
            <type>ejb</type>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>RetailProducts</groupId>
            <artifactId>RetailProducts</artifactId>
            <type>war</type>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

然后，当您打包EAR模块时，它将处理Web应用程序的依赖关系.参数skinnyWars控制是否应在WAR中复制依赖项.通常，您不希望它们出现在WAR中，因为Web应用程序可以从EAR本身访问它们.

Then when you package EAR module it handles dependencies for web application. The parameter skinnyWars controls if dependencies should be duplicated inside WAR or not. Usually you don't want them inside WAR since they are accessible to web application from EAR itself.
