[oliver.maven]

hi,all

after mvn jetty:run-war , i found there is no on other file in work directory 
except a lib directory which contains
many dependencies.
Then i got the 404 NOT_FOUND error When i visit the url,any way to solve this 
problem?

here is my coniguration:

     <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <version>6.1.6</version>
        <configuration>
          <scanIntervalSeconds>10</scanIntervalSeconds>
          <contextPath>/jmesa-test</contextPath>
          <webApp>${basedir}/target/jmesa-test.war</webApp>
        </configuration>
     </plugin>


i also got a Log error:
