Shouldn't this be `package = JPackage("myclasses")` as your Java code is 
contained in the package 'myclasses' not 'myclass'?

Change this last line to: `x = package.HelloWorld`
(class would be a better name than x IMO)

It looks like JPype exports Java classes as members of the object 
referred to by `package`. You then try and call it with () and python 
throws it's hands in the air as it must not be a callable.
