Solved FTB Local Server (Techworld2) does not startup

[Pappasmite]

Hi there,
I am quite new to this forum and haven't found any related topic which might have had a solution for my problem.
I downloaded the zip-file from the feed the beast hompeage, unzipped and started the .bat file.
It gave at first an error message "couldn'T acces .jar file, but got that fixed easily.

When I restarted the .bat file the server startup did not complete.
OS: Windows 7 Home Premium 64 bit
CPU:AMD Athlon II X4 640 3,00 GHz

RAM 12GB

From what I have understood ForgeModLoader is not running properly.

Any clues as to what I can change?

This is the problem: java.util.ConcurrentModificationException and it is caused by running java 8, I'd suggest uninstalling java 8 and installing java 7. If you don't want to change your java, you can try putting this into your mods folder: http://files.minecraftforge.net/LegacyJavaFixer/legacyjavafixer-1.0.jar. Or you can try this: http://www.minecraftforum.net/forum...-forge-1-6-4-1-7-2-java-8-compatibility-patch

Wow, this was a fast reply. Thank you very much. I will try to fix it asap. You are the man!

Hm.. I followed the instructions from http://www.minecraftforum.net/forum...-forge-1-6-4-1-7-2-java-8-compatibility-patch and opened the FTBServer-1.6.4-965.jar file with 7zz, dragged and dropped the CoreModManager.class file in the path mentioned in the instructions.
saved changes, restarted the serverstart.bat file, new error message, as was to be expected (security issue) http://pastebin.com/h9rVJrqq ... Hm.. deleted the META inf folder, but now the messag reads: Error: invalid or corrupt FTBServer-1.6.4-965.jar file.

Do I have to redoe this again and first delete the meta inf folder? What am I doing wrong?

Take a look at post #5 in that thread, it should have a fix.

Thank you again, that was just the right hint I needed.
So, my problem got fixed: Here I backtrack all the necessary steps to get an ftb server running.

1. DL the server files from FTB HP
2. Extract to a folder where you want your server files to be
3. DL CoreModManager.class this file from http://www.minecraftforum.net/forum...-forge-1-6-4-1-7-2-java-8-compatibility-patch
4. open the FTBServer-1.6.4-965.jar file with 7zz, drag and drop the CoreModManager.class file in the path cpw/mods/fml/relauncher
5. DO NOT DELETE the meta.inf folder, delete just the FORGE.DSA file

6. If not done already, edit the IP address according to the IP address the (server)-computer has.
run the serverstart.bat. wait patiently, then start ftb client (pay attention that you run the ftb client with the same mods as your server, i.e. monsters server - monsters client, techworld server - techworld client)

Probably a stupid question, but I can't seem to find out where to change the server IP address ?
