Answer 1

If you are not using maven, generate your projects war file and then go to your webapp directory which is under the tomcat folder. It might be something like that if you are using windows C:\\Program Files\\Apache Software Foundation\\Tomcat 7.0\\webapps copy war file here. Then under the bin\\ start your tomcat with startup.bat. This is old school method without maven. Take a look and research about maven.

Answer 2

yes I'm done ! just post here for if other people look at

I was add a web.xml file like that http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<filter>
    <filter-name>MainFilter</filter-name>
    <filter-class>MainFilter</filter-class>
    <init-param>
        <param-name>sleep-time-in-seconds</param-name>
        <param-value>10</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>MainFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
    <welcome-file>welcome.html</welcome-file>
</welcome-file-list>

And export my web to war file in webapps folder and change to ROOT.war notice : my MainFilter in default package
