Changes in source files of Maven project not reflected in tomcat

Question

My maven project is in final stage. I have deployed my war file to running tomcat instance by using mvn tomcat7:deploy command and the war file is exploded in the webapps folder. I can access all the source files in the war file through url. But the problem is, when i change anything in my source files ( jsp and servlet ) the updated war file is not reflected in the running tomcat server. my pom.xml is as follows.

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</project>

Am using maven 3.0.4 and tomcat 7.0.35. Pls help.

Try to call mvn clean install every time before running mvn tomcat7:deploy If you still have the problem, try mvn tomcat7:undeploy before. The undeploy removes the old war file und the deploy try to push the new one
