in order to package an *.ear, you don't need Websphere.
This can be accomplished with maven itself.
pom.xml:
<project>
...
<artifactId>YourApp</
<packaging>ear</packaging>
...
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-ear-plugin</artifactId>
<configuration>
<modules>
<jarModule>
<groupId>${project.parent.groupId}</groupId>
<artifactId>configurationApp</artifactId>
</jarModule>
<ejbModule>
<groupId>${project.parent.groupId}</groupId>
<artifactId>AnEjbModule</artifactId>
</ejbModule>
</modules>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
...
</project>
Then you add your dependencies.
On command line go to your project and run mvn package.
Because of the package defined in you pom.xml, the ear will be created and can be found in the YourApp/target directory.
On the websphere admin console you can simply install the ear.
After login, goto:
Applications->Websphere enterprise applications and install a new application.
Select your YourApp.ear and go for easiness through the fast path to install the app.
The port to check is probably
yourServerName:9080/YourApp.
Good luck.
