[Jython-dev] jython on WinCE/iPaq status

[Brian Z. <bri...@ya...>]

A little progress, thought the group would be interested:

I copied the jython.jar of 2.1a1 over, and tried to run a simple script
on pjava

    import java
    f = open('\\temp\\test1.txt', 'w')
    print >>f, java.util.Date()
    f.close()

The same script runs okay on pjava emulator on the desktop, but failed
with the following message:

    Traceback (innermost last):
      File "<console>", line 1, in ?
    ImportError: no module named java

in the java console. I noticed that different even from the pjava
emulator, the StrongArm pjava does not have rt.jar or classes.zip, in
stead, it got a larger javai.dll. I guess jython imports from the
classpath, that probably can explain why the import failed while --help
works fine.

Because WinCE does not provide a command prompt, testing the above
involves either using the "Run" dialog easter egg and typing the whole
pjava command line, or editing a shortcut from a connected desktop.

I also heard about the Visual Age Micro Edition from IBM, the j9 runtime
got a java console that accepts input, and uses classes.zip, so I might
give that a shot tonight.
