Plugin not found Exception, when using getPluginManager().getPlugin("aa")

Hello,

I’m developing a plugin in Openfire, but when i create a setting page and try to get the plugin instance, to transfer data to the plugin, i always get a Null Pointer Expection. I have been trying to fix this from a week.Please help.

teamFantasian_UserServicePlugin plugin = (teamFantasian_UserServicePlugin) XMPPServer.getInstance().getPluginManager().getPlugin(“teamFantasian_UserServic ePlugin”);

if(plugin == null) {

out.println(“Cant find plugin …!!”);

return;

}

Found the answer, always the name of the plugin should be lowercase and without special characters.
