Re: [jetty-users] Run multiple instances of the same WAR servlet and pass it a config value
Apologies, the getServletConfig().getContextPath() in the init() of my servlet works well, that probably had been a problem in my VS Code. Still I wonder, if I would set a "property" with a "name" and "value" as described in the "Jetty XML Syntax" section https://eclipse.dev/jetty/documentation/jetty-10/operations-guide/index.html#og-xml - how could I retrieve the value in the servlet?

Re: [jetty-users] Run multiple instances of the same WAR servlet and pass it a config value
I try to use the following but the method is not available:
@Override
public void init() throws ServletException {
super.init();
mLanguage = getServletConfig().getContextPath();
}

[jetty-users] Run multiple instances of the same WAR servlet and pass it a config value
Good morning,
I have an "overengineered" setup with Jetty 10.0.16 and haproxy 2.7.8,
where I currently run 6 different Jetty instances to serve the same servlet
-
I have programmed that WAR servlet using Maven and it supports 6 languages:
src/main/resources/strings.properties
src/main/resources/strings_de.properties
src/main/resources/strings_fr.properties
src/main/resources/strings_nl.properties
src/main/resources/strings_pl.properties
src/main/resources/strings_ru.properties
and then in the configure method I fetch the language value from the
"COUNTRY" env var:
@Override
public void configure(JettyWebSocketServletFactory factory) {
mLanguage = System.getenv("COUNTRY");
mBundle = ResourceBundle.getBundle("strings",
LOCALES.get(mLanguage));
factory.setIdleTimeout(Duration.ofSeconds(IDLE_TIMEOUT_SECONDS));
factory.setMaxBinaryMessageSize(0);
factory.setMaxTextMessageSize(64 * 1024);
factory.setCreator(new WordsCreator(this,
mBundle.getString(STR_DATABASE_URL)));
}
Then I have the following 6 scripts on my Rocky Linux 8.8 to start the
Jetty instances
/etc/systemd/system/jetty-de.service
/etc/systemd/system/jetty-en.service
/etc/systemd/system/jetty-fr.service
/etc/systemd/system/jetty-nl.service
/etc/systemd/system/jetty-pl.service
/etc/systemd/system/jetty-ru.service
And the only differences the scripts have is the port and the "COUNTRY" env
var:
[Unit]
Description=Jetty
After=network-online.target

Environment=COUNTRY=de
Type=simple
User=jetty

In the /etc/haproxy/haproxy.cfg I look at the request path and forward the
request to one of the ports:
backend jetty_de
server domain 127.0.0.1:8081 send-proxy
backend jetty_en
server domain 127.0.0.1:8082 send-proxy

use_backend jetty_de if { path_beg /de }
use_backend jetty_en if { path_beg /en }
use_backend jetty_fr if { path_beg /fr }
use_backend jetty_nl if { path_beg /nl }
use_backend jetty_pl if { path_beg /pl }
use_backend jetty_ru if { path_beg /ru }
default_backend jetty_en
Finaly my config XML files look like this to "bind" the servlet to a
certain context path:
# cat /var/www/jetty-base-de/webapps/de.xml
http://www.eclipse.org/jetty/configure_9_0.dtd;>
/de
/var/www/words-5.0.war
Thank you for reading my mail, it is a bit longer, because I am trying to
provide enough details.
My question is, if it is possible to handle my task with a single Jetty
instance?
Could I set the env var in the /var/www/jetty-base-de/webapps/de.xml file?
Or maybe alternatively access the value of "contextPath" from the
configure() method?
Thank you for any suggestions
Alex

Thank you Joakim for the extensive answer, however -

I have problems that my UTF8 file is displayed wrongly in the browser -
https://wordsbyfarber.com/Consts-ru.js
The browser displays pairs of junk characters instead of cyrillic letters
and from my (limited) experience having ";charset=utf8" in the header would
help it.
So I have followed your suggestion and have extended the
src/main/webapp/WEB-INF/web.xml with:
http://xmlns.jcp.org/xml/ns/javaee;
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd;>
WordsServlet
de.afarber.WordsServlet
WordsServlet
/
js
text/javascript;charset=UTF-8
Unfortunately the URL still returns the headers without "UTF-8" in there:
HTTP/1.1 200 OK
last-modified: Tue, 03 Oct 2023 09:52:40 GMT
content-type: text/javascript
accept-ranges: bytes
vary: Accept-Encoding
content-encoding: gzip
server: Jetty(10.0.16)
connection: close

[jetty-users] Setting text/javascript encoding to utf8 with Jetty 10.0.16
Hello, I am using Jetty 10.0.16 and when it serves static JavaScript files (I have Consts-en.js, Consts-de.js, Consts-fr.js, ...) the encoding is unfortunately not set to utf8 (like it is for the served json files). Is there a way to enforce that without compiling a custom version of Jetty? I have searched on the internet and also here: # find /usr/share/java/jetty-home-10.0.16 -type f -iname \*.prop\* /usr/share/java/jetty-home-10.0.16/modules/deprecated.properties /usr/share/java/jetty-home-10.0.16/modules/demo.d/demo-realm.properties /usr/share/java/jetty-home-10.0.16/modules/demo.d/demo-login.properties /usr/share/java/jetty-home-10.0.16/modules/sessions/infinispan/remote/resources/hotrod-client.properties /usr/share/java/jetty-home-10.0.16/modules/jolokia/jolokia-realm.properties /usr/share/java/jetty-home-10.0.16/modules/logging/jul/resources/java-util-logging-bridge.properties /usr/share/java/jetty-home-10.0.16/modules/logging/jul/resources/java-util-logging.properties /usr/share/java/jetty-home-10.0.16/modules/logging/jetty/resources/jetty-logging.properties /usr/share/java/jetty-home-10.0.16/etc/jdbcRealm.properties Thank you for any hints Alex ___ jetty-users mailing list jetty-users@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/jetty-users
