Hi there,
I try to use as many parts as possible from examples. I can't use the existing Web-Project of Xtext so i imported the war-file of it to another project (Eclipse-PlugIn) There I modified a existing Servlet which has doGet() und doPost() to a XTextServlet and put all the libs in a directory. To show up the WebPage with the Ace-Editor I used
getServletContext().getRequestDispatcher("/index.html").forward(req, resp);
Instead of index.html was a "jsp" in the original doGet()-Method.
How does ACE find the way back? How it connects to the LanguageServer-Servlet?
I see Ace in the Browser, no errors during booting the WebServer... but no connection. The files don't show me a url and i have no welcome-page like on the original Apache. I can't use the same setup but need a way to connect.
Thanks for help
Markus

I found two tutorials to add this websocket to monaco and xtext language server.
To connect it i use: const url = 'ws://localhost:4389', in the editor and commandline says it's connected.
The editor code has following:
// register Monaco languages
monaco.languages.register({
id: 'mydsl',
extensions: ['mydsl'],
aliases: ['MYDSL'],
mimetypes: ['application/Java'],
});
and
const editor = monaco.editor.create(document.getElementById("container")!, {
model: monaco.editor.createModel(value, 'mydsl',monaco.Uri.parse('inmemory:/MyDslParser')),
glyphMargin: true,
lightbulb: {
enabled: true
}
});
No idea how to teach Monaco mydsl from the server. I tried some things in ths Uri.parse(), but failed

everything should be mydsl. (thought that would be clear)
do you get any errors in client side console?
monaco.languages.register({
id: 'mydsl',
extensions: ['.mydsl'],
aliases: ['MYDSL', 'mydsl'],
mimetypes: ['application/mydsl']});
});
model: monaco.editor.createModel(value, 'mydsl', monaco.Uri.parse('inmemory://demo/model.mydsl')),
documentSelector: ['mydsl'],

Hi,
much better. Whenever i press the keyboard, a message goes to the server. The Language consists of 'Hello'? This doesn't find autocomplete. Just the words which are already in the editor.
message: {"jsonrpc":"2.0","method":"textDocument/didChange","params":{"textDocument":{"uri":"inmemory://demo/model.mydsl","version":59},"contentChanges":[{"range":{"start":{"line":4,"character":0},"end":{"line":4,"character":1}},"rangeLength":1,"text":""}]}}

i get this content assist answers
this is the request

this is the response
