JBoss EAP7 - 使用部署在另一只耳朵中的一个罐子

Question

我有一只耳朵，说 AAA.ear 和一只 war，说 BBB.war。

我的 AAA.ear 在库中有一个 jar，比如说 a.jar。我想要的是 BBB.war 使用 AAA.ear 中的 a.jar。

这是结构：

-AAA.ear
   - lib
      - a.jar


-BBB.war
    - META-INF
      - jboss-deployment-structure.xml

和jboss-deployment-structure.xml有以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <resources> 
            <resource-root path="."/>
        </resources>
            <dependencies>
            <module name="deployment.AAA.ear" export="true"/>
            </dependencies>
    </deployment>
</jboss-deployment-structure>

首先我部署了 AAA.ear 而不是 BBB.war 并且部署没有错误但是当我尝试使用 BBB.war 时我得到了异常：

注意：pt/mleiria/lixo/Lixo 是来自 BBB.war 的 class，他正试图调用 junit/framework/TestCase（这是我的 a.jar，位于 AAA.ear/lib文件夹）

问题是：有没有办法做到这一点？一个 war 文件使用位于一个 ear 文件的 lib 文件夹中的 jar？

提前致谢，

Answer 1

我不确定为什么会出现异常，但在重新启动和新的 depolyment 之后，它起作用了。
