[x3d-public] X3D python language binding, pyjnius validation

[John Carlson]

For example, in python files you send me, I think the following line:

jnius_config.set_classpath('.', '../../../jars/X3DJSAIL.3.3.full.jar')

Is not working.

I believe that CommentsBlock may be taken out of the X3Dautoclass.py file, since I don’t use it.  But may later.

My guess would be the classpath set by jnius_config…. Method is not working.

Hi John.  Status report.

a. am able to build on primary Windows 10 box,
b. still grappling with Visual Studio bug related to on Windows XP box,
c. have added build targets for X3D examples archives: clean.python and processScenes.python which work on first box,
d. .py generation works (see attached) but running self-validation of the two .py files still has problems.

Am getting a lot of these errors.  Do you have a bidirectional python-to-java mapping for x3djsail CommentsBlock when comments are encountered?

=====================
create python:
node xml2all.js C:\x3d-code\www.web3d.org\x3d\content\examples\X3dForAdvancedModeling/Visualization//TextureBackgroundCube.x3d
TextureBackgroundCube.py produced from TextureBackgroundCube.x3d
test python:
Loading and running TextureBackgroundCube.py program, if successful then saving as round-trip .x3d version:
Traceback (most recent call last):
   File "C:\x3d-code\www.web3d.org\x3d\content\examples\X3dForAdvancedModeling/Visualization//TextureBackgroundCube.py", line 5, in <module>
     from X3Dautoclass import *
   File "C:\x3d-code\www.web3d.org\x3d\stylesheets\java\src\python\pyjnius\X3Dautoclass.py", line 2, in <module>
     CommentsBlock = autoclass('org.web3d.x3d.jsail.Core.CommentsBlock')
   File "C:\Program Files\Python37\lib\site-packages\jnius\reflect.py", line 159, in autoclass
     c = find_javaclass(clsname)
   File "jnius\jnius_export_func.pxi", line 26, in jnius.find_javaclass
jnius.JavaException: Class not found b'org/web3d/x3d/jsail/Core/CommentsBlock'
Result: 1
=====================

In addition to example-project build.xml files, am also working with the pyjnius subdirectory build.xml still, but standing clear of your .py and .js files.

TIA for continuing insights and improvements.

all the best, Don
