I am very new to J/Link but I have been fiddling with it for a while
but I just don't see what was wrong:
I wrote a hello world program in Java and compiled it and put it in a
folder. Then I tried to call it from Mathematica using:
All these go well with the new class path added and
JavaClass["test",9] as output to the last line, but when:
Mathematica failed to created object because " there is no constructor
that takes zero arguments" even though I put in an explicit
constructor that takes no argument.
I tried putting in a constructor taking an int as an argument and using
test1= JavaNew["test",1]; (after reinstalling Java etc)
but now the type of the argument is wrong.
I think the class is either not properly loaded or something, but I
just dont' know what is wrong!!
Thanks a lot,
