doesnt work it forces me to use the old crafting style

If playing on vanilla servers forces you to use Classic Crafting, how did you come to the conclusion that it is an issue, and not a simple limitation?

If when JEI is not installed on the server side, the function of moving items to the crafting grid is disabled, why expect that a new interface that automates crafting would work?

so how would could i make that work on my server

Use a fabric/forge/neoforge server and place Legacy4J and its dependencies on it

like in the mods area?

yeah, in the mods folder

would it apply to everyone else in the server or just me

Only if these players are using fabric/forge/neoforge

everytime i try to load a server with legacy4j in the mods folder it crashes

Use a fabric/forge/neoforge server and place Legacy4J and its dependencies on it

with the dependencies?
