Deploying your web application to TomCat 7.0 using Maven

Deploying your web-application using the tomcat-maven-plugin can be done by as follows:

3. In your maven pom.xml configure the tomcat-maven-plugin as follows:


Take note of the

  • To redploy your war, use : mvn tomcat:redeploy
  • To undeploy your war, use : mvn tomcat:undeploy
