Force a "WebFilter" to be executed first

Consider the following filter mappings in my web.xml

<filter-mapping>
    <filter-name>rememberMeCookieFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>mustBeSignedInFilter</filter-name>
    <url-pattern>/private/*</url-pattern>
</filter-mapping>

As far as I understand from the tests I made, if I go to /private/account.jsp, the mustBeSignedInFilter will always be executed first (from what I could read, it's because the path is more specific). I need the rememberMeCookieFilter to be executed first.

How do I do that?

You're confusing filter mappings with servlet mappings. All filters matching the URL are executed in the same order as their filter mappings are been specified in web.xml. So swap the filter mappings and it'll work as you expected.

<filter-mapping>
    <filter-name>mustBeSignedInFilter</filter-name>
    <url-pattern>/private/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>rememberMeCookieFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
