带有Maven的多模块战争项目

Question

我尝试使用maven将我的单模块项目变成多模块项目。使用旧版本时，玻璃鱼服务器将按预期显示该页面。如果我将其移到具有maven的多模块概念的子模块中，它将无法正常工作。

我该怎么办？

我的旧（也是唯一的）pom.xml显示如下：

</project>

然后我创建两个文件夹，每个文件夹都像以下经文所示：

平台   -pom.xml   | -screwWebapp    -pom.xml   | screwEjb    -pom.xml

第一个pom显示如下：

<?xml version="1.0" encoding="UTF-8"?>

<modules>
    <module>screwEjb</module>
    <module>screwWebapp</module>
</modules>
</project>

screwEjb / pom.xml
