Server.jar file will not open by using a .bat file!

[Edmondson130]

Recently I've tried running a forge server and it works great! The only problem is I wanted to allocate more RAM for the server but my .bat file I'm using to open the server.jar file is giving me what looks to be a rather long error message. I always used this .bat file for my vanilla servers but I'm wondering if I need to change it for the forge server.

The .bat file is using this command line:

java -Xms1024M -Xmx1024M -jar forgeserverjar.jar

pause

Here is what I'm getting in the command window:

I don't know how forge works well enough to understand what's going on here.

Any information regarding to what I'm doing wrong or what is even going on would be great, thanks!

[Edmondson130]

Fixed and found the problem:

There was another version of java (Java 7) being found first and it wasn't using my Java 8 because the Java 7 version was found first.

So I simply replaced the java folder in the directory the command prompt was using with an updated version of java.

Thanks!
