I used the following command to generate a web application project:

mvn archetype:generate \

    -DarchetypeGroupId=org.apache.maven.archetypes \

    -DarchetypeArtifactId=maven-archetype-webapp \

    -DgroupId=com.mycompany.app \

    -DartifactId=my-webapp

Next step, I opened the project in Eclipse. When I click on "Run as => Run on server" the Hello World page is rendered in the web browser, but when I edit index.jsp the content is not updated.

What is more, I was observing my war package status in "Servers" tab - when I modified the file the status are changed to "republish", and changed again to "synchronized", but the content is not updated. Why?

My configuration:

- Linux Arch 64

- Eclipse Juno

- jBoss AS 7.1.1 Final

- Maven 3.0.4

- m2e 1.1.0.20120530-0009

- jBoss Tools

In attachment you will find my Eclipse project.
