Java wont let me start with 4gb of ram

Ok, so I was moving my server over from my laptop to my desktop and when i tried to start the server on ym desktop with -Xms4096M -Xmx4096M I got this error

Code:

Invalid initial heap size: -Xms4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
Press any key to continue . . .

any help?

 

I think you have 32b Java, you need 64b for this amount of memory.

 

That would make sense
I will give it a try

Ok
so i got 64bit java but it is still saying the same thing, is there somethign i have to change for it to realize i have 64 bit java?

 

if windows: use ie64 bit, go to www.java.com
else (or if you can't find ie64bit),
this page should always provide the latest jre
(click JRE under the java picture)

well.. i guess you didn't need that info

 

I have 64 bit java now, but it's still not working

 

It should not be the problem, but try omittin the -Xms option it is not even good to use that big AFAIK.

 

try starting your server with

java -d64 -Xincgc -Xmx4G -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui

 

Ok, So i used this in my server.bat

Code:

@echo off
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" 4096M -jar craftbukkit.jar
pause

and got this error

Code:

Exception in thread "main" java.lang.NoClassDefFoundError: 4096M
Caused by: java.lang.ClassNotFoundException: 4096M
        at java.net.URLClassLoader$1.run(Unknown Source)

        at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: 4096M.  Program will exit.
Press any key to continue . . .

what can I do to fix the file?

 

add -Xmx in front of the 4086M

 

@echo off
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -d64 -Xgcinc -Xmx4G -jar craftbukkit.jar
pause

 

first of all, that is probably not 64bit java.. (since it is in the x86 folder)

but your main error is caused by the lack of -Xmx in front of 4096m [should have been -Xmx4096M)

ninajed x2

 

ok I did that and I got yet another error

Code:

Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
Press any key to continue . . .

is is possibale i need to change the "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" part of it

 

drop the (x86) part and see if that fixes it

 

It does it does
success
^.^ thanks everyone I have no idea what I would do with you

 

Well waited in sadness and then got fed up with waiting and used google for a while and maybe solved it by yourself
