How to run the project after building with maven

Question

I am new to maven. So I have a project with pom.xml file. So I ran that with maven and the build was successful. I have glassfish. Glassfish is already running separately. So now what is the next step to run the project with Glassfish? My IDE is eclipse.

You have to first tell Maven to build the WAR, check out this plugin for that: http://maven.apache.org/plugins/maven-war-plugin/.

Then you need to tell maven how to deploy to glassfish, you can either configure a Maven execution plugin to do this (see here: https://www.mojohaus.org/exec-maven-plugin/). Or you can look around for a custom plugin devoted to integrating maven with glassfish. This one looks promising, but I have not used it: http://maven-glassfish-plugin.java.net/.

Maven provides a lot of basic functionality out of the box, but most of the cooler stuff with build automation is done through plugins.

Update

Just updating to add a very simple Pom that will do a auto-deployment. Note: if you just run a "mvn clean install", with the packaging set to 'war', maven will build the .war file for you and place it in the target/ folder. You can take this and deploy it to glassfish manually if you just want to get started.

Below is part of a very simple pom that uses the Maven execution plugin to auto-deploy to glassfish as a function of the build:

<build>
  <plugins>
    <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <executions>
        <execution>
        <goals>
              <goal>exec</goal>
        </goals>
        <phase>install</phase>
        </execution>
    </executions>
    <configuration>
        <executable>${path-to-asadmin-util}</executable>
        <arguments>
            <argument>deploy</argument>
            <argument>--user=${username}]</argument>
            <argument>--passwordfile=${password-file}</argument>
            <argument>--host=localhost</argument>
            <argument>--port=4848</argument>
            <argument>target/${project.name}</argument>
        </arguments>
    </configuration>
 </plugin>
 </plugins>
 </build>

This basically just calls the deploy command on the glassfish asadmin utility[1]. You need to fill in the following variables:

• ${path-to-asadmin-util} --> this is the path to your asadmin utility (normally in the glassfish_home/bin)
• ${username} --> glassfish admin username
• ${password-file} --> password file for logging into glassfish admin[2]
• ${project.name} --> name of your war

If you want to get more complicated I suggest taking a look at this thread: GlassFish v3 and glassfish-maven-plugin (Mac).

Answer 2

Additonnaly, you should have a glance at this StackOverflow thread, dealing with maven deployement in glassifsh : https://stackoverflow.com/a/1836691/1047365.

For further understanding of Maven, you should REALLY read this (free) book : http://www.sonatype.com/books/mvnref-book/reference/. This is THE reference for Maven.

We can explain you what Maven is doing, producing, etc ... but Sonatype made a great work and you'll probably learn more reading it than we could ever do !
