What is a "dependency" in modules?

[americanhorizon]

I'm following the official documentation. I've undertood that modules are group of classes and i can add a dependency between them... But what means exactly dependency? It's the same thing when i import libraries into a class?

It just means that one module depends (requires) the resources defined/contained in some other module.

You can add a module dependency in dependencies section of the module.xml file of a module.

Eg:

Added the following dependency to org.picketbox module in another module:

<dependencies>

     <module name="org.picketbox"/>

</dependencies>

and what is the difference with importing libraries directly into the class?

Are you talking of import statements in Java classes? Those are compile time dependencies that you are setting up. How and from where those dependencies get picked up at runtime is decided by your runtime environment. In case of AS7/WildFly that runtime environment for classloading is managed by JBoss Modules project and that's where the module.xml definitions for modules come into picture and that's where you specify the (runtime) dependencies.

Suppose that i've a class mailManager.java

and another class called subriscption.java. Inside this i import mailManager.java, when i deploy both on AS7 i should write the directory path in which they are positioned ? This is the dependecy that we are talking about?
