how do i make a 1.16.5 forge server run on java LTS 8

[GlaedrLudos]

ok so i downloaded the forge server files for 1.16.5, i made the run.bat file i renamed the forge server file to forgeserver.jar, and when i tried to run it, it keeps trying to run in java 16, which isnt supported. so i downloaded java LTS 8, but the server is still trying to run java 16. so all i need is how do i make it run with java 8.

 

[GlaedrLudos]

ok i understand the path thing, but where would i find the java version in the files

 

[GlaedrLudos]

got it

thank you

[GlaedrLudos]

ok i was wrong, i found the java folder but it only has java 16 in it. so im a little confused

Also what file type am i looking for?

ok its not working so i think i did it wrong but, is this somewhat how it should look?

instead of just "java"

"C:\Program Files (x86)\Java"

[GlaedrLudos]

ok i found the bin folder, theres a lot of exe files but no jar files

[GlaedrLudos]

the closest thing i see to the java -jar some-jar-file.jar you were talking about is a "Java.exe"

[GlaedrLudos]

ooooooooooooooohhhhhhhhh ok i think i get it

[GlaedrLudos]

ok so it stops the server very quickly and gives me this (this isnt the whole error message but i can send that if needed

 

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

also this is what the .bat file looks like

C:\Program Files (x86)\Java\jre1.8.0_301\bin\java -jar forge.jar -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

[GlaedrLudos]

ok so i did this 

"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java -jar forge.jar" -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

and it gave me this

'"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java -jar forge.jar"' is not recognized as an internal or external command,
operable program or batch file.

[GlaedrLudos]

oh wait, ok i put moved the second " to after java, and it says this instead. (idk if this means anything)

Error: Unable to access jarfile forge.jar

[GlaedrLudos]

so i need to put it in the bin folder?

[GlaedrLudos]

its not i was asking if it went there. i didnt think it should but i was just making sure XD

[GlaedrLudos]

yeah i have all my server stuff in one folder. but i just tried something i dont know if i was supposed to do it but i tried changing something in the bat folder, if its really messed up i can change it back.

it was this

"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java" -jar forge.jar -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

But now its this

"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java" -jar forgeserver.jar -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

And it gave me a decent load up but then gave me a big error

ok so put it back to how it was?

[GlaedrLudos]

ok so, what jar folder do i need in the server folder? i have the forgeserver.jar and the minecraft_server.1.16.5.jar, but im guessing i need something else as well

[GlaedrLudos]

hm. thats weird that its still not working then.

[GlaedrLudos]

"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java" -jar forge.jar -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

and by output do you mean the log? or is the output something else?

[GlaedrLudos]

like this?

"C:\Program Files (x86)\Java\jre1.8.0_301\bin\java" -Xmx4096M -Xms4096M -jar forgeserver.jar nogui
PAUSE

[GlaedrLudos]

ok let me try running it with that

[GlaedrLudos]

ok it gave me this

Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

[GlaedrLudos]

[GlaedrLudos]
