while starting tomcat.

My answer will be slightly off-topic but If I dare, I really recommend using jetty and using hot deployment in a separate process, not to launch it from within maven, but as a real server in /etc/init.d. Then you could deploy your app easily with an external script, activable from within eclipse, that will do a hot deploy of context in jetty.

It takes time to get this config but it's the fastest I have found and uses much less memory than using jetty within eclipse, and much much less than using tomcat. Hot deploy is also quite interesting in jetty.

You build cycle will look like

• edit / save from eclipse
• build / package through maven from eclipse (eclipse indigo is a charm for that)
• deploy your app in jetty through a external tool script from eclipse.

It has to do with tomcat looking for those classes in src/main/webapp/WEB-INF/lib, You can add the dependency plugin to your pom.xml like this.

   <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.3</version>
        <executions>
            <execution>
                <phase>install</phase>
                <goals>
                    <goal>copy-dependencies</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <outputDirectory>src/main/webapp/WEB-INF/lib</outputDirectory>
        </configuration>
    </plugin>

This plugin will copy all the pom dependencies to WEB-INF/lib and tomcat can find all the jars when you it out of workspace
