Re: [Jython-users] looking for jython tutorial for importing non-standard library java class

[Jacob F. <jac...@gm...>]

Hmm, it didn't work. Here's what I tried.

I have a class in foo/Test.java:
package foo;

class Test {
    public String print() {
        return "Printing\n";
    }
}


I compile it, then create a jar:
jar -cvf classes.jar foo


Then I run these commands in jython:
>>> import sys
>>> sys.path.append('/Users/jacob/projects/djython/jython_test/classes.jar')
>>> from foo import Test
>>> t = Test()
>>> t.print()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'foo.Test' object has no attribute 'print'
>>>


Hmmm. If I dir the t object I don't find a print function so I know it's not
there.

I feel like these steps I've followed should be working. If someone has a
few minutes to look at it and tell me what I'm doing wrong I'd greatly
appreciate it.
