B4J Question Jetty Server 12.1

Deal all or @Erel,

As I am losing money right now, because I cannot get to the market with an end of life Jetty Server, which I will be forced to replace and maybe change also my code later, I uploaded to ChatGPT the files of java code in the GitHub of Anywhere Software for Server and also the programming documentation of jetty server 12.1. It processed it thoroughly, made the necessary changes and it gave me back four of the files changed with the new requirements. I am not familiar with Eclipse nor do I know how to check it myself if it compiles and works correctly. Is anyone of you available and capable to check if it compiles? The code is in the attached zip file (the jetty12_1_... from chatgpt contains also the migration procedure).

Here is what ChatGPT wrote at the end:

I updated the Jetty-facing files from your uploaded set, especially JServlet, ServerWrapper, WebSocket, and WebSocketModule .

Main changes follow Jetty 12.1’s EE11 split: org.eclipse.jetty.ee11.servlet.*, org.eclipse.jetty.ee11.websocket.server.*, Handler.Sequence, server-level request logging, and Jakarta Servlet multipart Part handling. Jetty’s docs show EE11 servlet artifact/package usage and ServletContextHandler setup, plus Handler.Sequence and the Jetty WebSocket servlet pattern.

I could not compile-test because the sandbox lacks the B4X/AnywhereSoftware and Jetty jar dependencies.


Thanks in advance

@hatzisn i have similar issues with you.

I tried to port Jetty 12 over December but didn’t get anywhere

I have wrapped Undertow as an alternative. I’ve made the API as close as possible to jserver. I will post it here this weekend.

Undertow

undertow.io undertow.io

github.com

undertow-io

undertow-io has 11 repositories available. Follow their code on GitHub.
github.com github.com

The only reason I haven’t released it is because of the threading model it can’t be used in debug mode :(

Also the latest version of undertow doesn’t work with Java 11

Thank you for the reply... I have removed my file and kept only the original downloaded from ChatGPT. I also added in the original post what the ChatGPT reported. Can you check if it compiles?

Thanks for this. For now I will try to stick with Jetty Server. When you have time, please try to compile it and let me know if it works ok...
Also, I have removed my file from the first post and kept only the original downloaded from ChatGPT. I also added in the first post what the ChatGPT reported. I am rewritting it in order to be sure you have seen what ChatGPT reports.

Here is my trial. ChatGPT did make many mistakes (mixing Jetty 11 and Jetty 12 java code which failed compiling). In Jetty 12 they completely have rewritten WebSockets. Unzip it in libraries (it creates a folder jServer12.1.10) and the library jServer12.1.10.jar and jServer12.1.10.xml.


This is the first project after my brain surgery, so use carefully :cool:

Note: Needs Java 17+

EDIT Updated it to c3p0-0.14.1 and mchange-commons-java-0.6.1

Great work @alwaysbusy. You have got too much further than me.

No problem. Like I said it’s not for everyone. My experience with Undertow has been very positive but the lack of debugging is problematic.

I hope the members in here get Jetty 12 working so that we have more options 🍀

GetPolicy() is completely removed from Jetty 12. setMaxTextMessageSize is directly on the session object.

Code: Copy 
Dim MaxSize As Long = 5 * 1024 * 1024
Dim jo As JavaObject = ws

Dim session As JavaObject = jo.GetFieldJO("session")

session.RunMethod("setMaxTextMessageSize", Array(MaxSize))

If it is not in there then you can go to jetty server site in downloads and download the compressed file. All binaries are in the folder bin. There is though in the compressed file of @alwaysbusy the jetty-http2-hpack-12.1.10.jar.

Also in the library xml there is this:

B4X: Copy 
<dependsOn>jserver12.1.10/jetty-http2-hpack-12.1.10</dependsOn>
