Do I need both the minecraft_server jar and the forge jar?

[Serpardum]

I have installed my modpack and have it working in a single player environment and now I'm ready to set up my server where I am currently running a 1.5.2 forge server.  On my server I have one jar file, the one that I had combined the minecraft.jar file from mojang and the forge file from minecraft forge.  This as one file I put up in a special directory on my server they call /jar/

 

I notice I have a /libraries folder, my minecraft.jar file and the forge.jar file.  Do I need both the .jar files?  Did the installer copy the minecraft_server.jar into itself?  If I need both jars I just hope my provider allows one jar to call another.

You need both jars, as we don't ship minecraft code. We ship patches/segments.

As for you host, you'll have to talk to them, there should be no reason for them to disallow basic java functionality.
