Jython HashMap arguments

Question

I'm coding bukkit plugins for Minecraft servers in jython, using PyPluginLoader. I've events and everything else which works, but I want to make toggle command, which will toggle blockspawn mode on, but if you enter it again, it shuts it off. Here's the code, error below:

from java.io import File
import org.bukkit as bukkit
server = bukkit.Bukkit.getServer()
log = server.getLogger()
Material = bukkit.Material
from org.bukkit.event import player
from org.bukkit.entity import EntityType
import org.bukkit.permissions
from org.bukkit.plugin.java import JavaPlugin
from org.bukkit import Server
from org.bukkit import plugin
from java.util import Date, HashSet, HashMap

z = HashMap


@hook.command("blockspawn", usage="/<command>",
                desc="Toggles blockspawning mode on/off")
def onbrix(sender, command, label):
    if z.containsKey(player):
      z.remove(player.getName())
      sender.sendMessage("Blockspawning OFF")
    else:
        z.put(player.getName())
        sender.sendMessage("Blockspawning ON")

ERROR:

Caused by: Traceback (most recent call last):
  File "<iostream>", line 23, in onbrix
TypeError: containsKey(): expected 2 args; got 1

Please don't add off-site links, instead post the *relevant* parts of the error message and code here. — nanofarad, Oct 12 '13 at 16:56
Tracebacks are text too; copy it from the console (use the window menu to mark, then copy text) and paste it here. — Martijn Pieters, Oct 12 '13 at 17:09

I think your code should read:

z = HashMap()

Note the parentheses. Otherwise you are not creating an instance of HashMap.

Now I get this: Caused by: Traceback (most recent call last): File "", line 27, in onbrix TypeError: put(): expected 2 args; got 1 – Amar Kalabić Oct 12 '13 at 17:14
Maybe I'm not getting it, how do I exactly make an instance of HashMap? – Amar Kalabić Oct 12 '13 at 17:26
