You're incredibly impatient, but I'll assist.
You have to find a
SSP modification for Minecraft. That means most of the things on the MinecraftForums and on Bukkit.org's client-mod section.
You can't run "MobCatcher" by clicking on it because it is not supposed to do anything. It's an applet designed to load with Bukkit, and written to only do just that.
What do you mean you "executed" SPC to install it? That was most likely a launcher.

Wait a minute... Read your thread again.. So, okay. Hmm. I need someway to explain this to you. If you want to play SINGLEPLAYER (as in offline or only you can play) you don't need to run anything, or create anything. What you're doing now is creating a server on your computer. So, in order to do that (if you want to do this) do everything you're doing now, but make sure the port "25565" is port forwarded via your router/modem. Once that's forwarded, run your server and connect to it by connecting to: "localhost:25565" or "127.0.0.1:25565" (without quotes).
Did this help at all? If not, try and explain what you WANT to actually do.
You don't need to port forward to access localhost.

Okay this is exactly what I want.
-I have Single Player minecraft, ONLY. I do NOT have multiplayer minecraft, meaning I have MinecraftSP.exe downloaded. So, in that, I cannot connect to any servers, because it's simply SP, and I cannot get an account premium. I cannot buy anything and my parents will never let me.
-I have built a mob trap, and I've made a mistake. I just copied my mob room with MCEdit and cloned it all the way to the maximum height. Mobs were spawning everywhere and I was getting quite a bit of loot out of it. What I realized just after doing that, was I did not put half slabs to prevent spiders from spawning, AND, I made the ceiling 3 blocks high, resulting in endermen spawning.
-I have water canals that will push them into the lava grinder, and if endermen touches water, they teleport. And that's not good is it?
-Spiders will clog up the drop down-zone, because the drop-down zone is like 3x3x1, so it's quite small.
-I even spotted some slimes spawning, (rare, only seen it ONCE), so...this was a quite fail.
-So at this point, since SPC command CANNOT control which mobs to spawn and which do NOT, I surfed google for this mod/command.
-I came across this thing called "mobcatcher for Minecraft 1.2.5 ....info info blah blah blah"
-It said bukkit, and I had no freakin clue what the hell that was.
-I didn't care, so I just downloaded the jar file, and ran it, which is definitely pointless.
-By this point I have figured out you needed to install the "bukkit server".
-I did, by a video, and I put the jar file in the plugin folder and ran the run.bat. It created a folder, config.yml inside, and I changed the mob spawning to my desire.
-THINGS WERE SATISFACTORY UNTIL...THIS POINT.
-I ran the run.bat again, (minecraft was exited), to start up the server again.
-It said "done" (screenshot already posted), so I minimized it and ran Minecraft. (1.2.5 ofc)
-I tried everything, like /reload, /mobcatcher, everything.
-None worked. If you want to see a SS of what happens after I type any of those commands, feel free to tell me.
**THINGS I HAVE TRIED TO FIX THIS**
[] Re-installing bukkit server all over again.
[] Closing the cmd and running Minecraft.
[] NOT closing minecraft, then running run.bat, then unpausing game and trying it out.
[] Re-downloading plugin.
[] Trying out different plugins, like NOENDER, and Manta MobControl v1.0.
[] Checking for virus/checking for windows updates.
[] Updating minecraft.
MinecraftSP is still multiplayer. The jarfile name doesn't matter at all.
Enderman teleport on damage. That means lava, water, hitting them, cacti, the sun.
Bukkit is short for "Craftbukkit". It's server software with a specifically designed API to let programmers hook into.
If you are trying to install a mod, then read what it does before attempting to use it.
