Direct deployment of Web applications to Tomcat using Maven

Direct deployment of Web applications to Tomcat using Maven
1. Download and decompress Tomcat and configure environment variables so that Tomcat can be started successfully.

The decompressed version of tomcat allows you to conveniently view error information output by tomcat in the background for debugging.

2. Configure the username and password for tomcat.

Modify the/config/tomcat-user.xml under the tomcat installation directory to the following:

<?xml version='1.0' encoding='cp936'?><tomcat-users><role rolename="manager-gui"/>  <role rolename="manager-script"/>  <user username="username" password="password" roles="manager-gui,manager-script"/></tomcat-users>

The preceding configuration file is used to add a user named "username", "password", and "manager-gui" to tomcat.

3. Add the following code to the pom. xml file of the maven project.

<plugins>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            <artifactId>maven-compiler-plugin</artifactId>            <version>2.3.2</version>            <configuration>                <source>1.7</source>                <target>1.7</target>            </configuration>        </plugin>        <plugin>              <groupId>org.apache.tomcat.maven</groupId>              <artifactId>tomcat7-maven-plugin</artifactId>              <version>2.2</version>              <configuration>                  <url>http://localhost:8080/manager/text</url>                  <username>username</username>                  <password>password</password>                  <path>/${project.artifactId}</path>              </configuration>          </plugin>     </plugins>
