Im trying to create my own minecraft server but cant seem to even launch the jar file from java. What is this error code? I cant figure out how to fix it.

The error message "A java exception has occurred" generally indicates that there is an issue with the code or configuration of the Minecraft server. This error can be caused by various factors such as incorrect Java version, conflicting mods, corrupted files, or insufficient system resources.

To troubleshoot this issue, you can try the following steps:

Make sure you are using the correct Java version for running the Minecraft server.
Check for any conflicting mods or plugins that may be causing the error.
Verify that all necessary files for the server are present and not corrupted.
Increase the allocated memory for Java to ensure that there are enough resources for the server to run smoothly.
Consult online forums or communities for specific solutions to common Java exceptions in Minecraft servers.

If you are still unable to resolve the issue, consider seeking help from experienced Minecraft server administrators or developers who may have encountered similar problems before. Additionally, providing more details about the specific error message or log output can help others in diagnosing and solving the problem more effectively.

Can you share the specific exception?

languid venture Dec 1, 2024, 6:53 PM

#

#

ill share a snip

#

#

im just double clicking it

#

im gonna re install java now and see if it helps but im almost 100% sure i have the current version

#

what sucks is we just bought a little $100 PC to use as a server lmao

next current Dec 1, 2024, 6:59 PM

#

languid venture

run it from command line

languid venture Dec 1, 2024, 7:01 PM

#

can u explain how?

#

sorry im stupid and only code with xml lmao

little dune Dec 1, 2024, 7:01 PM

#

you know about "cmd"?

languid venture Dec 1, 2024, 7:01 PM

#

yeah the black box right

#

that i can type into

little dune Dec 1, 2024, 7:01 PM

#

yeah

#

you open that

languid venture Dec 1, 2024, 7:01 PM

#

what do i run tho?

little dune Dec 1, 2024, 7:02 PM

#

first you got to be in the same directory as the file

#

where is the server jar located?

languid venture Dec 1, 2024, 7:02 PM

#

just on my desktop rn if thats what you mean

#

in a file on my desk

restive prairie Dec 1, 2024, 7:03 PM

#

I guess I'd try to move it to you local disk first instead of running it on onedrive, finding the path for the microsoft cloud is a pain the butt

little dune Dec 1, 2024, 7:03 PM

#

then if you open cmd it should already be at your users account location
so simply running cd Desktop should work

languid venture Dec 1, 2024, 7:03 PM

#

im in the early stage where i dont associate it with minecraft yet

languid venture Dec 1, 2024, 7:03 PM

#

little dune then if you open cmd it should already be at your users account location so simp...

okay ill do that

#

cannot find the path

little dune Dec 1, 2024, 7:03 PM

#

restive prairie I guess I'd try to move it to you local disk first instead of running it on oned...

oh yeah, I wouldnt store such runnables in one drive

languid venture Dec 1, 2024, 7:04 PM

#

restive prairie I guess I'd try to move it to you local disk first instead of running it on oned...

where should i move it then?

#

bc the path to my desktop doesnt work for some reason

#

also thank you guys for helping i appreciate it a lot

restive prairie Dec 1, 2024, 7:04 PM

#

copy it to local disk c so it's directly on your computer drive

languid venture Dec 1, 2024, 7:04 PM

#

okay

little dune Dec 1, 2024, 7:05 PM

#

languid venture

you can also try clicking into this field and then typing cmd and press enter
this should open cmd in that context

languid venture Dec 1, 2024, 7:05 PM

#

i moved it to my main c drive, the whole file

restive prairie Dec 1, 2024, 7:05 PM

#

okay

languid venture Dec 1, 2024, 7:05 PM

#

little dune you can also try clicking into this field and then typing cmd and press enter th...

ooo okay i might try that too

restive prairie Dec 1, 2024, 7:05 PM

#

now you see your file alongside a bunch of folders right?

languid venture Dec 1, 2024, 7:05 PM

#

yeah all my normal ones

restive prairie Dec 1, 2024, 7:06 PM

#

right click on an empty space and "open with terminal"

languid venture Dec 1, 2024, 7:06 PM

#

ah hah

#

i think it worked

little dune Dec 1, 2024, 7:06 PM

#

essentially the command for running jar files is java -jar File.jar where you replace File.jar with the actual file name

languid venture Dec 1, 2024, 7:06 PM

#

restive prairie Dec 1, 2024, 7:06 PM

#

once you got the terminal opened type "dir" just to check if the folder's there

little dune Dec 1, 2024, 7:06 PM

#

languid venture

that looks good

languid venture Dec 1, 2024, 7:07 PM

#

#

would a vc be easier or nah

restive prairie Dec 1, 2024, 7:07 PM

#

#

little dune Dec 1, 2024, 7:07 PM

#

languid venture would a vc be easier or nah

little dune Dec 1, 2024, 7:09 PM

#

languid venture

you need a newer version of java

#

what is your current version?

languid venture Dec 1, 2024, 7:09 PM

#

says its been compiled by a more recent version

little dune Dec 1, 2024, 7:09 PM

#

you can check with java -version

languid venture Dec 1, 2024, 7:09 PM

#

i just downloaded the most current one

little dune Dec 1, 2024, 7:09 PM

#

I doubt that

#

or its using a different install

languid venture Dec 1, 2024, 7:09 PM

#

little dune Dec 1, 2024, 7:09 PM

#

java 8 is old

restive prairie Dec 1, 2024, 7:09 PM

languid venture

languid venture Dec 1, 2024, 7:09 PM

#

oh lord lmao

#

WTF

#

HAAHAHA

little dune Dec 1, 2024, 7:10 PM

#

check this:

sweet scarabBOT Dec 1, 2024, 7:10 PM

Download latest Java from https://adoptium.net/, run the installer.

Open a CMD and type java -version and javac -version, if both show your new Java version, you have successfully installed Java! 🎉
https://i.ibb.co/X8Kms8q/CurMujt.png

In order to prevent issues with old installations you may want to remove them. Type where java and where javac. They should only show the new and no old entries:
https://i.ibb.co/fkKHv0b/x5k1GxG.png

If that is not the case, you may want to clean up. Therefore, type "environment variable" into the Windows search and follow the dialog. You will see two entries for a variable called Path, one for your user and one for the system. This variable tells Windows where to look for commands, like java and javac.
https://i.ibb.co/BwvMpM6/3bN9QE2.png

Edit both. Make sure that they only list the entry to your new Java installation and remove all the old entries you have seen with the where command before:
https://i.ibb.co/9GTnHsm/JAYog1U.png

Confirm and close all dialogs. Restart your CMD window and try where java and where javac again. It should only list the new installation now and nothing else.

Congratulation, your Java is now finally ready, happy coding 🎉

now you need to do what it says, update the EULA

languid venture Dec 1, 2024, 7:14 PM

#

i see a "failed to load properties"

little dune Dec 1, 2024, 7:14 PM

#

first update the EULA

languid venture Dec 1, 2024, 7:14 PM

#

okay

little dune Dec 1, 2024, 7:14 PM

#

the server should usually generate that properties file on its own

languid venture Dec 1, 2024, 7:14 PM

#

it said type eula.txt

#

but i got nothin but red text

little dune Dec 1, 2024, 7:14 PM

#

wdym, there should be such a file in that directory

#

open it with some text editor

#

and update it

languid venture Dec 1, 2024, 7:15 PM

#

little dune Dec 1, 2024, 7:15 PM

#

not there

#

in your folder

languid venture Dec 1, 2024, 7:15 PM

#

oh duh

little dune Dec 1, 2024, 7:15 PM

#

languid venture Dec 1, 2024, 7:16 PM

#

languid venture

this seems broken

languid venture Dec 6, 2024, 5:10 PM

#

thats what i think

little dune Dec 6, 2024, 5:10 PM

#

there is no jar file

languid venture Dec 6, 2024, 5:10 PM

#

it looks weird

#

and when i press run it opens my cmd

little dune Dec 6, 2024, 5:10 PM

#

well run wont properly work without the jar file

little dune Dec 6, 2024, 5:10 PM

#

languid venture and when i press run it opens my cmd

but yeah thats what its doing

languid venture Dec 6, 2024, 5:10 PM

#

its not downloading for some reason

#

this is the forge one

#

from ver 19

#

why is it not downloading?

little dune Dec 6, 2024, 5:12 PM

#

I cant help with that information

#

thats too broad

languid venture Dec 6, 2024, 5:12 PM

#

actually i think i made it look funny

#

look at it now

little dune Dec 6, 2024, 5:12 PM

#

run isnt downloading anything

#

thats not how it works

#

you download the server jar from the website

languid venture Dec 6, 2024, 5:13 PM

#

little dune Dec 6, 2024, 5:13 PM

#

that also wont work

languid venture Dec 6, 2024, 5:13 PM

#

little dune you download the server jar from the website

im thinking about using cursedforge for everything atp

little dune Dec 6, 2024, 5:13 PM

#

also why is one of them a text document

languid venture Dec 6, 2024, 5:13 PM

#

is there a better reason to use a manual style like this over cursed forge?

little dune Dec 6, 2024, 5:13 PM

#

no idea how that works 🤷‍♂️

languid venture Dec 6, 2024, 5:14 PM

#

can someone vc with me and help me lmao

little dune Dec 6, 2024, 5:25 PM

im just having issues with folders installing and dont know if im doing them right

this thread was mostly fixing my java

little dune Dec 6, 2024, 5:28 PM

languid venture im just having issues with folders installing and dont know if im doing them rig...

you actually need to give details, no one can help you with just that

languid venture Dec 6, 2024, 5:28 PM

#

idk what u want me to show u

#

i have no idea whats wrong

#

i know that something isnt downloading even though im using forges thing

#

and thats the jar file

little dune Dec 6, 2024, 5:30 PM

#

languid venture i have no idea whats wrong

I dont either with that little context

languid venture Dec 6, 2024, 5:34 PM

#

its saying i havent agreed to the eula

#

the file does look how its supposed to tho

#

its different with this mod installation

#

but i definitely agreed to the eula already

#

the bottom of the script says i need to agree to the eula first but i have

little dune Dec 6, 2024, 5:36 PM

#

you sure you look at the correct eula?

languid venture Dec 6, 2024, 5:36 PM

#

im opening the one in this file

little dune Dec 6, 2024, 5:36 PM

#

otherwise its still pretty hard to follow what exactly you are doing right now

languid venture Dec 6, 2024, 5:36 PM

#

im worried ive closed out others or something but ive done this 3 times now

#

thats why i wanna screenshare lol

little dune Dec 6, 2024, 5:37 PM

#

how are you creating the server?

languid venture Dec 6, 2024, 5:38 PM

#

i go to the forge files site, go to 1.19.4, download reccomened

#

then i install the jdk server to my desktop minecraft file

#

and everything works as intended hold for the eula part

little dune Dec 6, 2024, 5:39 PM

#

you sure you saved the eula file properly?

languid venture Dec 6, 2024, 5:39 PM

#

ill try again rn

#

wow

#

im fucking stupid

#

closing it wasnt saving the registery lmao it was just saving the text

#

sorry bro ty for your patience
