What is the easiest way to start tomcat in embedded mode from the cargo-maven2-plugin?

Question

I have defined tomcat:catalina:5.5.23 as a dependency to the cargo plugin, however I still get the following exception:

java.lang.ClassNotFoundException: org.apache.catalina.Connector
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)

at java.lang.Class.forName(Class.java:247)
at org.codehaus.cargo.container.tomcat.internal.Tomcat5xEmbedded.preloadEmbedded(Tomcat5xEmbedded.java:232)

It looks like the RealmClassLoader is not finding the class, possibly due to java.security.AccessController.doPrivileged denying access.

Has anyone got tomcat to run in embedded mode from within maven?

Answer 1

Side note: You can start jetty which is similar to tomcat. (Servlets will be available at http://localhost:8080/ artefact-name)

mvn jetty6:run

You would have to add to your pom:

<project>
    <build>
        <plugins>
            <plugin>
                <groupId>org.mortbay.jetty</groupId>
                <artifactId>maven-jetty6-plugin</artifactId>
                <configuration>
        <scanIntervalSeconds>5</scanIntervalSeconds>
        <!--
        <webXml>${basedir}/WEB-INF/web.xml</webXml>
        -->
       </configuration>
         </plugin>
         </plugins>
    </build>
</project>

There is also a tomcat maven plugin:

http://mojo.codehaus.org/tomcat-maven-plugin/introduction.html

<plugins>
  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
  </plugin>
</plugins>

On my machine this loads up tomcat 6. I'm not sure how to get it to work with tomcat 5.5
