You don't have a provider in your classpath.
Add one.
You have many to choose from.
Jetty's own jetty-slf4j-impl, or logback, or log4j2, or java.util.logging,
etc ...
Read the documentation at the link in the warning message.

Thank you, Joakim, now my servlet runs, but -

Jetty 10 prints:

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details.

And then I don't see any logs printed by my servlet with

Logger LOG = Log.getLogger(LOG_TAG);

LOG.info("");

And thus I cannot find out why there is no data returned from PostgreSQL...

Maybe this line does not really work?

factory.setCreator(new WordsCreator(this,
mBundle.getString(STR_DATABASE_URL)));

My servlet is multilanguage and thus I was passing differen DB credentials
with the line above.

What should I please use instead instead of Log.getLogger()? There
is @deprecated, but no replacement suggestion.

Best regards
Alex

You are using a JettyWebSocketCreator.

Get rid of  factory.register(WordsListener.class);

2021-09-03 Thread Alexander Farber

Hi, thank you for the helpful hints, now my WAR compiles.

However when I launch it by:

1) First running once on Win 10 / Java 11:

java -jar jetty-home-10.0.6\start.jar jetty.home=jetty-home-10.0.6
jetty.base=jetty.base
--add-module=http,servlet,webapp,deploy,resources,websocket

2) Then running

@SET JETTY_HOME=%~dp0\jetty-home-10.0.6
@SET JETTY_BASE=%~dp0\jetty.base
java -Djdbc.drivers=org.postgresql.Driver -jar %JETTY_HOME%\start.jar
jetty.home=%JETTY_HOME% jetty.base=%JETTY_BASE%

Then Jetty 10 starts fine initially:

2021-09-03 17:59:51.475:INFO :oejsh.ContextHandler:main: Started
