Alternate port for Tomcat (not 8080) when starting with Maven?

Question

Is there an easy way to specify an alternate port for Tomcat in the pom or on the commandline. I'd like to have several projects running on the same machine.

Answer 1

If you are using the maven tomcat plugin, you can specify a context.xml by adding a plugin configuration block to the pom.xml:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>tomcat-maven-plugin</artifactId>
        <version>1.0-beta-1</version>
        <configuration>
          <mode>both</mode>
        </configuration>
      </plugin>
    </plugins>
  </build>
  ...
</project>

The default context.xml file used is located at src/main/webapp/META-INF/context.xml.

Set different ports there.

Answer 2

Using the syntax given on http://mojo.codehaus.org/tomcat-maven-plugin/run-mojo.html, you can directly specify the port:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>tomcat-maven-plugin</artifactId>            
  <configuration>          
    <server>tomcat-development-server</server>
    <port>9966</port>
  </configuration>
</plugin>
