How do I fix this error?

I tried to make my first plugin but I get this error and have no clue how to fix it .

Code:

Feb 1, 2011 11:09:37 AM org.bukkit.plugin.SimplePluginManager loadPlugins

Any help is appreciated

 

Did you forget the plugin.yml file?

 

Nope, it's in there.

 

it can't find your plugin class (the one extended from JavaPlugin)

check the "main" line in your plugin.yml:

main: your-class-here

for example:
main: org.bukkit.myname.myplugin
where "myplugin" is the class extended from JavaPlugin

 

I think the best for you would be to post the plugin.yml here and the source file (or at least the header of the source file).

 

plugin.yml: http://pastebin.com/FhL7bZqX
MyEcon.java: http://pastebin.com/4WxvGfhz
MyEconPlayerListener.java: http://pastebin.com/dtTtGtEH
LoadSettings.java: http://pastebin.com/hJ7YvUZK
PluginProperties.java: http://pastebin.com/evQBxzfK
Accounting.java: http://pastebin.com/pYBxSKvq

 

you have:

main: com.bukkit.DanielR.MyEcon

but it should be:

main: com.bukkit.DanielR.MyEcon.MyEcon

 

Oh ok thanks
