A friend and I share a private server and we've been trying to set it up for industrial craft but are having some difficulties. Now I am no stranger to modding clients but am rather new when it comes to setting up and running a server. I've gotten my client to run IC2 without any problems and figured the server would be just as easy. This is not the case. We're running minecraft 1.2.3 on both our machines and the server is running the 1.2.3 server jar. As far as we can tell we installed the proper mods listed on the wikis download page but we keep getting java.net exception errors. We have tried numerous combinations of mod versions thinking that maybe that is where we went wrong. I was wondering if you guys could give me some advice on what we're doing wrong. Here is what we're doing just for clarity sake.
Drag and drop modloadermp into the server jar.
Drag and drop forge into the server jar.
Placing the IC2 jar into the mods folder.
We haven't deleted the META-INF folder in the server jar because the few places I've seen it mentioned says not to. I remember seeing something about a server fix but I can't remember where or if its even relevant. If I am leaving out any important information I can easily remote into the server and get it. Any help you could offer would be appreciated greatly.
