In this tutorial, we will show you how to use Maven-Tomcat plugin to package and deploy a WAR file to Tomcat, both in Tomcat 6 and 7.

Libraries used :

Maven 3
Tomcat 6.0.37
Tomcat 7.0.53

Tomcat 7
Deploy URL = http://localhost:8080/manager/text
Command = mvn tomcat7:deploy

Tomcat 6
Deploy URL = http://localhost:8080/manager/
Command = mvn tomcat6:deploy

1. Tomcat 7 Example

This example shows you how to package and deploy a WAR file on Tomcat 7.

1.1 Tomcat Authentication
Add an user with roles manager-gui and manager-script.

%TOMCAT7_PATH%/conf/tomcat-users.xml

<?xmlversion='1.0'encoding='utf-8'?><tomcat-users>   <rolerolename="manager-gui"/><rolerolename="manager-script"/><userusername="admin"password="password"roles="manager-gui,manager-script"/>   </tomcat-users>

1.2 Maven Authentication
Add above Tomcat’s user in the Maven setting file, later Maven will use this user to login Tomcat server.

%MAVEN_PATH%/conf/settings.xml

<?xml version="1.0"encoding="UTF-8"?><settings ...><servers>   <server><id>TomcatServer</id><username>admin</username><password>password</password></server>   </servers></settings>

1.3 Tomcat7 Maven Plugin
Declares a Maven Tomcat plugin.

pom.xml

<plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><url>http://localhost:8080/manager/text</url><server>TomcatServer</server><path>/mkyongWebApp</path></configuration></plugin>

How it works?
During deployment, it tells Maven to deploy the WAR file to Tomcat server via “http://localhost:8080/manager/text” , on path “/mkyongWebApp“, using “TomcatServer” (in settings.xml) username and password for authentication.

1.4 Deploy to Tomcat
Commands to manipulate WAR file on Tomcat.

mvn tomcat7:deploy 
mvn tomcat7:undeploy 
mvn tomcat7:redeploy

Example

> mvn tomcat7:deploy
 
... [INFO] Deploying war to http://localhost:8080/mkyongWebApp
Uploading: http://localhost:8080/manager/text/deploy?path=%2FmkyongWebApp&update=true Uploaded: http://localhost:8080/manager/text/deploy?path=%2FmkyongWebApp&update=true(13925 KB at 35250.9 KB/sec)   [INFO] tomcatManager status code:200, ReasonPhrase:OK [INFO] OK - Deployed application at context path /mkyongWebApp [INFO]------------------------------------------------------------------------[INFO] BUILD SUCCESS [INFO]------------------------------------------------------------------------[INFO] Total time: 8.507 s [INFO] Finished at: 2014-08-05T11:35:25+08:00 [INFO] Final Memory: 28M/308M [INFO]------------------------------------------------------------------------

2. Tomcat 6 Example

This example shows you how to package and deploy a WAR file on Tomcat 6. The steps are same with Tomcat 7, just the deploy url and command name are different.

2.1 Tomcat Authentication

%TOMCAT6_PATH%/conf/tomcat-users.xml

<?xmlversion='1.0'encoding='utf-8'?><tomcat-users>   <rolerolename="manager-gui"/><rolerolename="manager-script"/><userusername="admin"password="password"roles="manager-gui,manager-script"/>   </tomcat-users>

2.2 Maven Authentication

%MAVEN_PATH%/conf/settings.xml

<?xml version="1.0"encoding="UTF-8"?><settings ...><servers>   <server><id>TomcatServer</id><username>admin</username><password>password</password></server>   </servers></settings>

2.3 Tomcat6 Maven Plugin

pom.xml

<plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat6-maven-plugin</artifactId><version>2.2</version><configuration><url>http://localhost:8080/manager</url><server>TomcatServer</server><path>/mkyongWebApp</path></configuration></plugin>

2.4 Deploy to Tomcat

mvn tomcat6:deploy 
mvn tomcat6:undeploy 
mvn tomcat6:redeploy

Example

 
   > mvn tomcat6:deploy
   
  
   
 ...
