I haven't tested this at all, but it seems to me that: 
my $jc=main::com::schooner::test::JumpClass::getInstance();

Is wrong: it's not a method call. You should probably use: 
my $jc=main::com::schooner::test::JumpClass->getInstance();

[download]

Note the -> arrow. That will ensure amongst other things that the "class" will be passed to the getInstance() method.

edit: you can also leave off the "main::" part of the package.
