Unable to set RAM of server. "Adv. terminal features r not available in this environment."(1.20.1/47.2.0)

[Foobert]

I can play my server & others can connect to it but it cannot load certain chunks & times out because it's bottlenecked by the default 4GB. I know this to be the case because when copy+pastaing the exact server world into curseforge singleplayer with 8G+, all the heavy chunks load in fine. 
I have JavaSDK 17.0.9 x64-bit & reinstalled twice already as well as trying with Java 8 also installed & without. 
I tried using: java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.20.1-47.2.0/win_args.txt %*
pause
but all that gives me is: Error: Could not find or load main class java
Caused by: java.lang.ClassNotFoundException: java 
Any ideas or help would be appreciate.

Make sure you are using Java 17 by setting the path into your script

"C:\Program Files\Java\jdk-17.0.9\bin\javaw.exe" -Xmx8G @libraries/net/minecraftforge/forge/1.20.1-47.2.0/win_args.txt %*
pause

Hm. I did try adding that in the user_jvm_args.txt but I get this: 
Error: Could not find or load main class C:Program FilesJavajdk-17.0.9binjavaw.exe
Caused by: java.lang.ClassNotFoundException: C:Program FilesJavajdk-17.0.9binjavaw.exe
Press any key to continue . . .

I tried both with "\jdk-17\" (as it appears in the program files) as well as "\jdk-17.0.9\" 
No luck. am I placing it in the wrong file? Could the second part be incorrect?

Do not remove the quotation marks

 

[Foobert]

I didn't. The quotation marks are still around the file path first part. & tried with quotation marks both jdk-17 & -17.0.9. Just double-checked.

Also make sure the path is correct - check your system for the Java 17 installation and copy the path to the javaw.exe

[Foobert]

That's what's so odd. Because I shift-clicked to get the file path & it literally is the same exact thing: (copy + pasted from folder) "C:\Program Files\Java\jdk-17\bin\javaw.exe"

Try another Java build

https://www.azul.com/downloads/#zulu

and set the path to

C:\Program Files\Zulu\zulu-17\bin\javaw.exe

[Foobert]

Yep. I just don't know. I get this still when I run the batch. 
Error: Could not find or load main class C:Program FilesZuluzulu-17binjavaw.exe
Caused by: java.lang.ClassNotFoundException: C:Program FilesZuluzulu-17binjavaw.exe
Press any key to continue . . .

I also double-checked & made sure that I was using the 64-bit one for my computer & that the file path was correct. It was. Is it my actual run.bat that could be the issue? Or do I have messed up associations from having downloaded different javas even though I uninstalled them through control panel? idk. I'm not that savvy.

Add the lines of your start bat file

[Foobert]

Okay. Thank you. I think it works now. I added the jdk-17 path to the batch instead of the jvm arguments txt file. The windows command prompt is just blank, but when I close the native windows command prompt, the java command prompt opens & loads the server. If that won't cause issues then I'm all good. 

[Foobert]

Okay. I think I got it. Thank you for the help though. I realized I need both scripts in the batch.

I was wrong.
