Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app : <project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

For simple projects, archetype:generate seemed too heavy for me, but creating the standard Maven file structure by hand is such a chore. So I created this simple script to ease the pain: #!/bin/sh if [ $# -lt 4 ]; then echo "Us... Example usage: ./initmvn.sh myProject theGroupId theArtifactId co...

It's easiest to use the archetype plugin to start a new Maven project. I'll use struts 1 as example since it's not in the built-in archetypes for archetype:generate . Generate a simple webapp with archetype:generate : C:\work\maven>mvn archetype:generate -DarchetypeAr... It generates a directory structure like this: struts1app struts1app/pom.xml struts1app/src... with a simple POM: <project xmlns="http://maven.apache.org/POM/4.0.0"... Create settings.xml in $HOME/.m2 , add Java.net repository for Java EE dependencies: <?xml version="1.0" encoding="UTF-8"?> <setting... Add Java EE and Struts dependencies in pom.xml . Note that the Java EE dependency has scope provided , meaning that the web app container provides the jars, therefore we don't need to bundle them with our war fie. <project xmlns="http://maven.apache.org/POM/4.0.0"... Create a directory named java under main , create the Struts form and...

To start a simple "Hello World" project in maven, enter: mvn archetype:create -DgroupId=com.example -Dartif... in the command line. It will take a while for Maven to run. But eventually it will create the standard Maven directory structure with a "Hello World" app and a fake JUnit test. Enter mvn package will build the simple App into a jar under the target directory. Run the resulting App: C:\maven\hello-world>java -cp target\hello-world-1... This is the generated pom: <project xmlns="http://maven.apache.org/POM/4.0.0"...
