I hava a maven project, pom.xml contains tomcat plugin.
org.apache.tomcat.maven
tomcat7-maven-p
Have you tried changing the context path by setting it in the configuration section of the Maven plugin?
FYI: Find the current version of the plugin here
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path>
</configuration>
</plugin>
I am using tomee and it works for me.
Add the context tag to the pom file as follows:-
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
..
<context>ROOT<context>
..
</configuration>
</plugin>
