Server Fails to launch when adding new mods

[jrDN]

I am trying to add Thermal Foundation, Thermal Expansion and CoFH Core mods to my Tekkit Legends server located on my dedi box, i am not experienced in any way shape or form with java so i really have no clue whats going on.

I put the said mods into the server folder named mods with the rest of the Tekkit Legends mods, i run the server start.bat but the server does not launch correctly, i remove the 3mods and all is fine.

When i add the mods to my client and run single player, there is no problems and all works as expected, am I missing something?

Thank you in advance for any assistance.

First put cofhcore in there, start the server, then put the other 2 in
