Hello @yyoncho I have created a file lsp-camel.el. I have placed this file under "~/.emacs.d/elpa/lsp-mode-8.0.0".

This is the content my lsp-camel.el file.

I have created init.el file.

This is the content my init.el file.

;; Comment/uncomment this line to enable MELPA Stable if desired.  See `package-archive-priorities`

(custom-set-variables

I was able to successfully provide Text Editing capabilities of Camel URI with Camel JAVA and XML. But I'm trying for Yaml with the above mentioned files. I'm not able to see any editing capabilities for Yaml.

Please is there any sequence of steps that I should follow in order to achieve this task?

What happens when you do M-x lsp in yaml-mode?

[Navyashree0923]

Do you mean I have to run M-x lsp-install-server after opening the yaml file?
Please correct me if i'm wrong, thanks.

[yyoncho]

No, M-x lsp

Hello @yyoncho sorry for the late reply. I see the camel-ls and Yaml-ls is activated but the provided completion sounds to be a dictionary completion
