It's the one with the little blue and red coffee cup on the icon. You would be well served by turning on "always show file extensions" for your folders. Google can help with that.

It's a Class Cast Exception. Basically a java class file (in this case Obsidian TNT) cannot be cast to another class file (a mob it seems). Try running your server on peaceful difficulty and see if that helps.

@AsunaYuki: You are missing the libraries for your server. Use the latest version of Cauldron (formerly known as MCPC+) and run the installer.

When I download the zip from the 1.6.4 link, chrome (my browser) blocks the file as malicious (malware). Is there somewhere else I can get a template? I think all I really need is the text to go in a .txt document to turn into a batch. I dont actually want to run a server on my PC, but rather make a separate zip file for anyone else to run a server for my modpack.

MCPC+ (now Cauldron) and normal Forge libraries: https://copy.com/qLsTvZfUUkkb

 

I'm back. When I download your link plowman I get some 1.6.4 libraries. I actually fixed this a month ago but I don't remember how. I think I replaced the libraries folder in my launch directory with what you posted. However I am still getting the error. Am I missing something? Is there more to this? I'm using MCPC, not cauldron for 1.6.4.

 

Do I need a repaired server.jar too?

I just updated the file downloaded with that link (same URL) to include the newer required libraries for Cauldron. You really should be using Cauldron instead of MCPC+ in almost all circumstances.

I've updated the OP to include Cauldron (the successor to MCPC+) versions of the 1.6.4 and 1.7.2 server files. I've also added a Cauldron 1.7.10 server file download, enjoy!

I followed your guide. And my server still won't work. I am using a lot of mods though. I posted another thread about this already, but figured I'd post here and maybe you could help me. I am willing to compensate someone who knows what they're doing, to walk me through setting up my own server by explaining it over skype, or if you could just set up a server for me with my mod pack, and send me the server file/folder. Please help, I've been trying to figure this out for too long.

thats my modpack. Please, please help.

@SXScarecrow: Your Cauldron downloads in the OP are incomplete.

  • Cauldron no longer automatically retrieves its library files. One must run the Cauldron installer to get all the required libraries.
  • It would be helpful to reference which version of Cauldron you are providing.
  • It would be helpful to provide a link to the official Cauldron downloads. http://files.minecraftforge.net/Cauldron/

I don't understand I download the server file and it says some libraries are missing and need to be added and turns off, all that happens in fraction of second.

@Shayd: As I mentioned in my last post to you, directing you to my previous response, please READ that post. The original post in this forum has the required information when combined with my post above here. A simple google search of "minecraft cauldron server" takes you right to the main site and wiki for the project.

I followed the steps it says to do, but when I click launch the command window pops up for less than a second then closes. I don't know how to fix it, I've tried deleting it all and redoing it and it didn't help.

As

plowmanlpow said the download does not download the required libraries. You will have to do it yourself http://files.minecraftforge.net/Cauldron/

My own take on how to make a client and server pack:

  • Getting your mods:
  • Using my BareBonesPack to make a client pack:
  • Resolving ID conflicts:
  • Creating the server:

@bear251170: Read the links provided here. They will probably help you.

@bear251170: It would be best at this point to start a new thread in the Server Op Swap Shop forum so as not to pollute this thread. Include a link to your API URL in the post as well as a link to your latest Forge logs and the most recent crash report if you have one.

@DiddlyDoo802:

java.lang.IllegalArgumentException: Slot 1000 is already occupied by [email protected] when adding [email protected]

A clear case of a block ID conflict at ID #1000. This post about fixing ID conflicts may be helpful:

 

On another note, problems like this probably belong in the Server Op Swap Shop. This thread is more about "how to make a server" than "I need help with my setup". If everyone who needed server/pack help used this thread it would get so polluted it would be useless.
