Updating to craftbukkit 0.3 bug 3 :(

hey guys, another problem when i try updating my plugin to 1.7.2 r0.3. (this plugin works for 1.7.2 Beta 0.2)
after a squish one bug (with your help with some of them) another pops up.
i think this is the last one, due to the fact of the plugin will boot, it when i do a action i get the error

anyway onto the bug.

Code:

that's the error i get.
the code is here.
ShipsMain = http://dev.bukkit.org/paste/hpzt42s3qe8yno6r/
ShipsMapping = http://dev.bukkit.org/paste/hd6ybog2ratc5vi9/
ShipsListener = http://dev.bukkit.org/paste/wca9zovbxklm26de/

i know this code is not a work of art, i know this code can be improved so much, but im new to java ... just over a month, so please, dont comment to say how shocking my code is, unless your comment is to fix the code, or make it better

 

i think its because your extending the base class that extends javaplugin, try not doing that

 

clienthax
how do you mean? dont you need to extend the main class into JavaPlugin to get the plugin to boot?

 

Yes. but you extend in ShipMapping your Main and thus JavaPlugin again. I think thats what he is on about

 

thanks guys, its working now
