Maven dependency type ejb vs jar

Question

What is the difference between

    <dependency>
        <groupId>groupId</groupId>
        <artifactId>artifactId</artifactId>
        <type>ejb</type>
    </dependency>

and

    <dependency>
        <groupId>groupId</groupId>
        <artifactId>artifactId</artifactId>
        <type>jar</type>
    </dependency>

Answer 1

<type>ejb</type> is needed when your artifact artifactId has EJBs and you want to use them. If you don't need the EJBs in your module <type>jar</type> is an option.
