error main class could not be found or loaded

[Fuzzyma]

Description

Installing the vscode extension produces popups notifying that the language server crashed 5 times.
Lookingh at the logs, it seems like the java class java.lang.ClassNotFoundException: org.eclipse.lsp.cobol.LangServerBootstrap is not found

Steps to reproduce

• Open code in wsl with code .
• Install extension

Expected behavior

Extension should work

Screenshots

Language server crashes

Environment

Win10 with wsl (5.15.146.1-microsoft-standard-WSL2)

Additional information

Could you let me know how you installed the extension?

[Fuzzyma]

I used the vscode extension menu.
The first time if was installed, it was installed as a dependency of another cobol extension.
I also removed and reinstalled the extension multiple times. With no luck.

The vscode windows that I used was opened through "code ." in the wsl terminal. Afaik that means the vscode server runs on wsl whole the interface runs on windows (?)

Thank you for your response!

Could you please check the cobol ls extension in the %USERPROFILE%.vscode\extensions (~/.vscode/extensions in the case of Linux) folder? There should be broadcommfd.cobol-language-support-[vertsion]/server/jar folder. Please share the server.jar from there.

One more thing:
Please try to start the server in native mode. To do that, go to vscode settings and set the cobol-lsp.serverRuntime property to native.

The vscode windows that I used was opened through "code ." in the wsl terminal. Afaik that means the vscode server runs on wsl whole the interface runs on windows (?)

I'm not a Windows user, but I expect the JVM to run the server in the same environment as a node that runs vscode. I'm not sure that it can be related to the path. Otherwise, I would expect something like a jar not found exception.

[Fuzzyma]

So in windows, there is no such extension. I guess thats because I installed the extension on the linux side.
However, on linux, there is only a .vscode-server folder but that indeed contains the server.jar.
Since only zips are allowed, I uploaded it here.
server.zip

I tried the native mode already and that indeed works. What makes the whole thing a bit unusable for me is that "SCREEN SECTION" is not supported. Any chance to make that work?

@Fuzzyma it looks like windows java is being executed under WSL which causes issues with paths. Could you, please, try installing java in your WSL environment and see if the issue persists?

[Fuzzyma]

As far as I can see, I have java installed on WSL as well:

The upper one is wsl, the below is windows

$ which java
/usr/bin/java
