Maven耳朵项目与ejb和战争模块 [英] Maven ear project with ejb and war modules

问题描述

我在使用maven和Jboss 7的web应用程序上工作3个模块ejb ear和war所以战争将ejb作为依赖，而ejb将同时成为耳朵的模块，所以当我这样做时我在这棵树上得到两次相同的ejb

im working on a web application with maven and Jboss 7 wich conatins 3 modules ejb ear and war so the war will have the ejb as dependancy and the ejb will be in the same time a module of the ear so when i do this i get the same ejb twice this tree

ear
...Mywar
........Myejb
...Myejb

此结构是否正确或我应该更改另一个

is this structure is correct or i should change another

战争的pom.xml：

the pom.xml for the war :

推荐答案

配置EAR模块的正确方法是拥有EJB jar依赖于WAR模块中的提供范围，并且直接在EAR下使用EJB jar，如下所示：

Right way to configure EAR Module is to have the EJB jar dependency with "provided" scope in WAR module and having EJB jar directly under EAR like the below:

EAR
|
|-lib/someutil.jar
|-EJB.jar
|-my-web.war
|  |-WEB_INF/lib
|    |-coolutil.jar
|-EJB2.jar

但my-web.war可以依赖于任何EJB.jar，但它在运行时由容器解析。因此，在WAR的pom.xml中将ejb依赖项标记为已提供（按容器）。

But the my-web.war can dependent on the any EJB.jar, but its resolved in runtime by container. So, mark that ejb dependency as "provided" (by container) in WAR's pom.xml.
