Message4602

I wanted to play around with this, so I applied both patches. Then ran
it, and typed in your example ... it failed because it couldn't import
ctypes. I look again and realized that you didn't include ctypes itself
... so I copied it out of my CPython install (Python v2.5.2 from Ubuntu
8.04.2 x64) The ctypes/__init__.py mentions something about being
v1.0.3. At this point I get:
Jython 2.5b3+ (trunk:6266M, Apr 27 2009, 21:48:35)

Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
Traceback (most recent call last):

    actual, required = sizeof(typ), calcsize(typecode)
struct.error: bad char in struct format

I seems that the "P" char is not understood by the struct implementation
in Jython (it works in my CPython).
