The document discusses the Apache Tomcat Maven Plugin, including an overview of its history and development. It describes some key things the plugin allows users to do: run a WAR project within an embedded Apache Tomcat instance during the Maven build, and deploy the WAR to a running Tomcat server. The document outlines features like running in debug mode, generating executable JARs, and using an Maven archetype to generate a sample project structure.

Maven will download all necessary jars to run an embeded Tomcat. In Maven3 multi modules project, reactors projects automatically added to the webapp classloader : no need to install all jars dependencies. Easy developpement of webapp : no need of restart/install war when modifying jsp/css etc... Debug in your ide with mvnDebug.

Attach the deploy goal to the deploy phase in a profile and your build war will be deploy in a running Tomcat instance. Simple : mvn deploy -Ptdeploy Run the Maven lifecycle (build your war, deploy it to your Repo Man and deploy it to your Tomcat instance)
- 7. © Talend 2011 7 Executable jar/war Mojo goal to build a standalone jar to run your war. Jar will include your webapps and all necessary Tomcat jars. Cli : mvn tomcat7:exec-war produces a jar my-project-exec-war.jar Simply your project : jar -jar my-project-exec-war.jar Come with some default setup: http port, default server.xml But optionnal cli options : -httpPort -ajpPort etc.. (RTFM :-) )
- 8. © Talend 2011 8 Maven archetype There is now an archetype : mvn archetype:generate -DarchetypeGroupId=org.apache.tomcat.maven -DarchetypeArtifactId=tomcat-maven-archetype -DarchetypeVersion=2.0-SNAPSHOT Generate a standard multi modules Maven project : * basic-api (service interface) * basic-api-impl (service default impl). * basic-webapp (our webapp module) * basic-webapp-exec (module to generated executable war) * basic-webapp-it (module to run selenium tests with generated war)
