Multiple module maven project questions

This is the directory structure of my project

seam-glassfish
 |-- ear
 |    |-- pom.xml
 |-- ejb
 |    |-- src
 |    |-- pom.xml
 |-- war
 |    |-- src
 |    |-- pom.xml
 |-- pom.xml

This is the parent pom.xml:

<modelVersion>4.0.0</modelVersion>
<groupId>home</groupId>
<artifactId>seam-glassfish</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>seam-glassfish</name>
<modules>
    <module>ejb</module>
    <module>war</module>
    <module>ear</module>
</modules>
<!-- nothing special about other parts -->

This is my ejb/pom.xml:

<modelVersion>4.0.0</modelVersion>
<artifactId>seam-glassfish-ejb</artifactId>
<packaging>ejb</packaging>
<name>seam-glassfish-ejb</name>
<parent>
    <groupId>home</groupId>
    <artifactId>seam-glassfish</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>
<!-- nothing special about other parts -->

This is my war/pom.xml:

<modelVersion>4.0.0</modelVersion>
<artifactId>seam-glassfish-war</artifactId>
<packaging>war</packaging>
<name>seam-glassfish-war</name>
<parent>
    <groupId>home</groupId>
    <artifactId>seam-glassfish</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>
<dependencies>
    <dependency>
        <groupId>home</groupId>
        <artifactId>seam-glassfish-ejb</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

This is my ear/pom.xml:

<modelVersion>4.0.0</modelVersion>
<artifactId>seam-glassfish-ear</artifactId>
<packaging>ear</packaging>
<name>seam-glassfish-ear</name>

<parent>
    <groupId>home</groupId>
    <artifactId>seam-glassfish</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>

<dependencies>
    <dependency>
        <groupId>home</groupId>
        <artifactId>seam-glassfish-ejb</artifactId>
        <version>1.0-SNAPSHOT</version>
        <type>ejb</type>
    </dependency>
    <dependency>
        <groupId>home</groupId>
        <artifactId>seam-glassfish-war</artifactId>
        <version>1.0-SNAPSHOT</version>
        <type>war</type>
    </dependency>
</dependencies>

I have some questions here:

1. How to tell the maven-ear-plugin to use my application.xml? And where in the ear directory should I place my own application.xml?

2. Because of the dependency on the ejb, I have to run mvn install in the ejb directory before I can run mvn compiler:compile in the war directory. Is there any way (like target dependencies in ant) to tell maven to compile / install all modules needed before the mvn compiler:compile is executed?

3. In my application.xml, beside the ejb and war modules, I need to add one more module like this:

<module><ejb>jboss-seam-2.1.1.GA.jar</ejb></module>

The jboss seam jar file can be found with a <dependency>. What should I do to tell maven to include that file into the root of the ear file it creates when I run mvn ear:ear in the ear directory?

4. If I don't want to create the seam-glassfish-ear-1.0-SNAPSHOT.ear file, but a seam-glassfish-ear-1.0-SNAPSHOT_ear directory in which the ejb module is unpacked in the seam-glassfish-ejb-1.0-SNAPSHOT_jar directory, the war module is unpacked in the seam-glassfish-war-1.0-SNAPSHOT_war directory and the jboss seam library above is unpacked in the jboss-seam-2.1.1.GA_jar directory, what should I do?

I read the http://maven.apache.org/plugins/maven-ear-plugin/ but found no shine to my questions (maybe there are, but not apparent to a maven newbie like me).

Thank you.

The m-ear-p is able to autogenerate an application.xml for you. Maybe you
should try to use this feature. See [1] for details.

If auto-generation doesn't fit your needs, I'd put my application.xml in
src/main/resources/META-INF/application.xml of my ear module. IMHO, this
should work.

Your dependencies are incorrect! You missed they <type>ejb</type> in your
war dependency declaration.

Not 100% sure what you want to achieve. Did you try specifying the seam
artifact as a normal dependency (with scope runtime) of your EAR?

The default directory for ear sources is src/main/application. If you put
your application.xml file in src/main/application/META-INF/application.xml,
Maven will pick it up automatically. Most users let maven generates it for
you. The ear plugin does that by default.

Well, you invoke mvn package at the root level and it will do that for you.

Make it a dependency :) If you need something, it needs to be a dependency.
You miss the <type>ejb</type> in the jboss-seam dep.

Read the doc a bit more. To explode the modules, there's an option for that
http://maven.apache.org/plugins/maven-ear-plugin/examples/unpacking-a-module.html

For the EAR itself there's a feature request (
http://jira.codehaus.org/browse/MEAR-51) but you can have a direct solution
with the dependency plugin (unpack goal)

Question 1,2,3 are not maven ear plugin's question but Maven questions. You
better have to read more tutorial on Maven itself first

HTH,
