[Jython-users] jast.Block in jythonc?

[Tim C. <ti...@2w...>]

Hi

I've been experiencing Jython 2.0 - jythonc failing on Win NT without giving
any indication that all is not well. 

c:>jythonc xyz.py

eventually executes Compiler.compile(..), in which the line:

	code=jast.Block(pi.executeString(data))

causes the program to exit.

I note in Tools\jythonc, jast is a directory which contains the directories
Statement, Output and Modifier; there isn't one called Block, which
according to this code I would have expected. As a result the program just
exits (without warning). Anyone else have this directory?

Thanks

Tim

It is more than just a directory, it is also a package. A Package is a
directory with a __init__.py file in it. When importing the package, the
__init__.py file is executed. The jast/__init__.py file contains the
line: 

  from Statement import *

and the Statement.py file do contain a Block class. So this is not the
reason why jythonc is failing.

You didn't tell which jvm you are using, but I bet it is MS jview. A bug
somewhere (I put the blame on microsoft) prevent jview from running
jythonc.

I suggest that you install and use a JVM from javasoft instead. If you
are trying to create browser applets you should use a JDK1.1, otherwise
pick the JDK1.3.
