[jetty-users] Using WebAppContext at contextPath / but also serving imag

[Alexander Farber <alexander.farber@xxxxxxxxx>]

Hello dear Jetty users and developers,

I am using 9.4.43.v20210629 for two things:

1) serve Websockets and GET, POST requests

2) serve files located in "images" and "sounds" folders

My config for 1 is currently using contextPath "/ws":

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"

    "http://www.eclipse.org/jetty/configure_9_0.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

    <Set name="contextPath">/ws</Set>

    <Set name="war">/var/www/myservlet-3.0.war</Set>

</Configure>

And the two configs for 2 are (only the "resourceBase" differs):

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"

    "http://www.eclipse.org/jetty/configure_9_0.dtd">

<Configure class="org.eclipse.jetty.server.handler.ContextHandler">

    <Set name="contextPath">/images</Set>

    <Set name="handler">

        <New class="org.eclipse.jetty.server.handler.ResourceHandler">

             <Set name="resourceBase">/var/www/html/mydomain.com/images</Set>

            <Set name="directoriesListed">true</Set>

        </New>

    </Set>

</Configure>

It works well for several years already (and behind HAProxy 1.8.27), but I am not happy with having  contextPath "/ws" as a prefix to my servlet.

I would like to change it to "/" aka root, but wonder how to keep "/images" and "/sounds" also servable by Jetty.

Would org.eclipse.jetty.fcgi.server.proxy.TryFilesFilter help me in this situation?

If a file (a sound or image file) is found, it should be served. Otherwise the Websockets, GET or POST request should be forwarded to my servlet.

In the Jetty doc for FastCGI there is an example:

    <Call name="addFilter">

        <Arg>org.eclipse.jetty.fcgi.server.proxy.TryFilesFilter</Arg>

        <Arg>/*</Arg>

        <Arg>

            <Call name="of" class="java.util.EnumSet">

                <Arg><Get name="REQUEST" class="javax.servlet.DispatcherType" /></Arg>

            </Call>

        </Arg>

        <Call name="setInitParameter">

            <Arg>files</Arg>

            <Arg>$path /index.php?p=$path</Arg>

        </Call>

    </Call>

but I am not sure how to apply it to my situation, how to replace the "index.php" by my servlet there?

Best regards

Alex
