B4J Question B4J-Bridge under Linux

[peacemaker]

Hi, All

Trying for first time to start B4J apps in Linux from Win10 via B4J-bridge.
Java 11 is default in Ubuntu 22.04:

~$ java --version
openjdk 11.0.16 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)
vlad@vtk1:~$

I did not copy Java files (maybe mistake ?)
And default GuessMyNumber server's app is started with the error

Starting Bridge like:

sudo jdk-11.0.1/bin/java -jar b4j-bridge.jar

does not help also:

Under Win10 app is started and working in the browser OK.

App is started under Ubuntu, but works wrong...
Where to dig ?

jServer v4.0 - Based on Jetty 11

Starting from B4J v9.80 this library is included as an internal library. Old library: https://www.b4x.com/android/forum/threads/141323/#content This is a new version of jServer. It is based on Jetty 11.0.9. Previous versions were based on an early version of Jetty 9. There were many improvements...

Did you successfully implement the new jetty?

Or are you still using jserver3?

Read now, thanks, but did not understand where "b4j_ws.js" should be placed - sorry, nowere mentioned, how to implement ?
jServer was updated to v.4.01.

And locally under Win10 app (jetty) is OK...

BTW, URL "http://127.0.0.1:51042/guessmynumber/guess" gives reply "Please enter a valid number.".
So, app looks working somehow, but the root URL http://127.0.0.1:51042 gives 404.

Something in Jetty settings on Linux side ?

p.s. where is placed root html of:

Server Examples​

• Guess My Number
• Guess My Number - WebSockets
  ?

SOLVED: folder "www" is not copied by the Bridge to Linux , sorry - really noob is starting to touch Linux and server apps...

hi peacemaker!
Jserver has 2 ways of serving pages. the one you need is an static file:
http://127.0.0.1:51042/guessmynumber/
try with this URL. (please notice the / at the end)

you can find this file in: Objects/www/guessmynumber
