NetherOres crashing on server start

[Dallandra]

Title: NetherOres crashing on server start

Version: 3.1.1

OS: Windows 7 Professional

Java Version: 1.6.0_31

Description of Problem:

The server can't load mod_NetherOres.jar, since it apparently doesn't contain any mods/that "unsupported major.minor version 51.0" bullshit keeps it from recognizing the mod.

However, using the "Generate Nether Ores" port found here

http://www.minecraftforum.net/topic/1210034-125sspsmpbukkit-generate-nether-ores-122-bugfixed-again/

works just fine after changing the block ID from 150 to 135.

Error Messages:

See Error Log.

2012-08-02 13:56:13 [iNFO] File mod_NetherOres.jar contained no mods

[Backplague]

Get Java 7.

[Adambanana]

Hey i have this problem aswell, but on the java site they don't have windows x32 so what should i do?

[Nentify]

Windows x86 is 32-bit.

This is the result of a corrupt file.

Windows Solution:Redownload the same Tekkit server version you are currently running from the Technic website. Unpack and replace any files that "failed to read properly."

 

In my situation this error appears to be a result of using WinSCP to transfer unpacked files to the Ubuntu Server. This may apply to others running an Ubuntu or other Linux server. See linked thread for more information http://forums.technicpack.net/threads/3-1-server-item-conflicts.16153/page-2#post-125740

 

Linux Solution: copy a compressed version of the Tekkit server you want to run (ex. Tekkit_Server_3.1.1.zip) to your Ubuntu (or other Linux based) server and unpack it directly on the server using a local or remote terminal session.

 

Recommendations: Use Putty on Windows for a remote terminal session. http://www.chiark.greenend.org.uk/~sgtatham/putty/

install p7zip on the server

sudo apt-get install p7zip

 

use p7zip to extract the Tekkit server

p7zip -d Tekkit_Server_3.1.1.zip

Note to Windows users: Just in case you aren't aware, Linux and Ubuntu are case sensitive. Type commands above exactly as they appear, or type the file name exactly as it appears in the directory if using a different file.

ls

If you want to transfer an existing server from Windows to Ubuntu:

Install 7zip on Windows and use it to repack your existing server. http://www.7-zip.org/download.html
