Hello I keep getting this error whenever I try to load up any forge server using a server.bat file. I'm now using 1.16.5 forge version 36.2.31  I'm using java 17 and java jdk 8. Ive reinstalled my java jdk and java 17 as I thought that was the problem, but that doesn't work.

Make sure you run the server with java 8, you can replace the 'java' in the bat file with full path of java 8. If the server runs with java 8 post updated debug log

okay, I might have typed the string out incorrectly when replacing java with 'java 8' Anyways this is the new error

C:\Users\james\Desktop\1.16.5 forge server>java 8 -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
Error: Could not find or load main class 8
Caused by: java.lang.ClassNotFoundException: 8

You need to replace 'java' with the full path of java 8

okay I keep running into issues.

first this is how my bat file is set up now. 

Files\Java\jre1.8.0_321 -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
pause

this is the new error I get. 

C:\Users\james\Desktop\1.16.5 forge server>Files\Java\jre1.8.0_321 -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
The system cannot find the path specified.

C:\Users\james\Desktop\1.16.5 forge server>pause
Press any key to continue . . .

 

I also tried it when the bat file looked liked this.

C:\Program Files\Java\jre1.8.0_321 -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
pause

This is the error I get

C:\Users\james\Desktop\1.16.5 forge server>C:\Program Files\Java\jre1.8.0_321 -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\james\Desktop\1.16.5 forge server>pause
Press any key to continue . . .

Im still really confused

The java executable is at bin/java inside the Java installation directory. It also looks like you did not specify the actual full path.

I might sound stupid for asking this but how would I do that then?

go into the bin/java folder of the java installation you want to use to run the server and copy the full path and use it instead of java in .bat file

okay so I went to my drive that has java installed, I went to Program Files, I went to java, I opened Jre1.8.0_321, I opened the bin folder, I copy the path, looks like this: C:\Program Files\Java\jre1.8.0_321\bin

in the .bat file I put these ' at the beginning and end as program files is two words and it wasn't recognizing the full path.  as a result of all of this i get the error 

C:\Users\james\Desktop\1.16.5 forge server>'C:\Users\james\Program Files\Java\jre1.8.0_321\bin' -Xms4G -Xmx6G -jar forge-1.16.5-36.2.31.jar -nogui
The filename, directory name, or volume label syntax is incorrect.

C:\Users\james\Desktop\1.16.5 forge server>pause
Press any key to continue . . .

 

I also tried doing that but with the program files (x86) folder java both don't work. 

what did I do wrong or is there a program that I don't have downloaded that is making this fail 100% of the time as ive never had this issue trying to make a personal forge server.
