Hi, thanks for the advice, But I want to avoid harcoded links such as $APACHE_HOME\httpdocs\images or <a href="http://yourdomain/images/1.jpg";> in my jsp. Indeed I don't want to modify these values if I decide Tomcat to run on another port, or to install Tomcat in another directory or even OS. That is why I am looking for an approach using the webapp context, so I don't have to worry about the OS, or the port, or whatever configuration.
