Any problems installing and using Jython on the Mac OS X?

Yes!

I've had lots of luck using the java xml stuff from Jython.

My sax parser looks a little like this:

import java
from org.xml import sax as java_sax

class NeuroinfoHandler(java_sax.helpers.DefaultHandler):
  """
  A handler to deal with Neurionfo Dumps in XML
  """
  defs =3D {}
  tagChars =3D None
  currentDefinition =3D None
  currentInstance =3D None
  currentInstanceData =3D None

  def __init__ (self, store, userSession):
    self.store =3D store
    self.session =3D userSession

  def startElement(self, uri, name, qname, attrs):
    #print '.', name, qname,
    if name =3D=3D "neuroinfo":
      self.version =3D attrs.getValue("version")
      print 'version', self.version

    elif name =3D=3D "definition":
      d =3D mbf.neuroinfo.NiDefinition()
      d.definedAs =3D attrs.getValue("definedAs")

    elif name =3D=3D "attribute":
      if self.currentDefinition:
        da =3D mbf.neuroinfo.NiDefinitionAttribute()
        da.name =3D attrs.getValue("Name")
        da.npClassName =3D attrs.getValue("jclass")
        da.definedBy =3D attrs.getValue("definedBy")
        da.defaultValue =3D attrs.getValue("default")

        self.currentDefinition.addAttribute(da)

      elif self.currentInstance:
        attribName =3D attrs.getValue("name")
        attribValue =3D attrs.getValue("value")
        self.currentInstance.setAttribute(attribName, attribValue)
      #
    #

    elif name =3D=3D "data_base64":
      if self.currentInstance:
        if self.tagChars:
          self.currentInstanceData =3D =
base64.decodestring(self.tagChars)
          self.tagChars =3D None
          #print "Have Data", self.currentInstanceData[0:100], "..."

  def characters(self, characters, start, length):
    # characters is a byte array (org.python.core.PyArray), we want to
append it to a string
    if self.tagChars !=3D None:
      self.tagChars +=3D characters[start:start+length].tostring()

def importNi (filename, storage, userSession):
  """ start a parser give it a handler, and feed it the file """
  fr =3D java.io.FileReader(filename)
  inputSource =3D java_sax.InputSource(fr)

  handler =3D NeuroinfoHandler(storage, userSession)
  xr =3D java_sax.helpers.XMLReaderFactory.createXMLReader()
  xr.setContentHandler(handler)

  xr.parse(inputSource)

  fr.close()

[Jython-users] Question

[Tony Maniaci <tmaniaci@tr...>]

I am considering using Jython. Can you access the Java XML libraries
from Jython?

RE: [Jython-users] Eclipse and Jython/Python

[nr nr <news0reader@ho...>]

I think it would be a sizeable plus for jython evangelism (?) and huge plus 
for its development to have Eclipse [-calibre] support: project management 
(module organization), file manipulation (compare, etc), collapsible code 
outlining, integrated step-through debugging, etc.

While all that's beneficial to jython I'm left wondering what Eclipse would 
have to gain.

Perhaps with jython integrated into its IDE, Eclipse could offer better 
scriptable customization.  Not sure, though that that spot may not be better 
filled by a more java-like scripting language like BeanShell or Rhino.

RE: [Jython-users] Eclipse and Jython/Python

[Updike, Clark <Clark.Updike@jh...>]

An Eclipse plug-in would be a big plus for jython.  I think it would also
help
breed confidence in potential users.  The main issue I have with mixing a 
java/jython code base is the lack of a refactoring IDE for jython (although
a nice 
debugger would clearly be in second place).  Maybe I'm spoiled by having a 
refactoring-capable IDE for java (Eclipse), but it sure would be nice to
have 
changes to java code ripple through to the jython code (and vice versa).  I 
expressed much the same sentiment in  
http://sourceforge.net/mailarchive/forum.php?thread_id=1947088&forum_id=5586
.  

So I guess my list of benefits would be, in descending priority:

1. Integrated Jython/Java refactoring
2. An integrated debugger
3. Gain many of the generic Eclipse features (project/file management,
   package explorer, local history/compare/replace, etc.)
4. A monolithic environment for java/jython development
5. Could use the Eclipse update manager for plug-in and core jython updates

At one point I saw some interest in the Eclipse Forums for a jython plug-in,
and I even tried to follow up with the people involved but never heard back
from anyone.

Hope this helps,
Clark

I would like to hear from anyone ASAP that is using Eclipse or would like to
use Eclipse with Python/Jython.

  http://www.eclipse.org/

I think it would be great to get full syntactic support for Jython/Python
and have Jython embedded into Eclipse. Since Jim Hugunin is listed as one of
the Eclipse sub-project leads I figure at least some people involved with
Eclipse might be sympathetic to this idea, but I have not been able to reach
Jim yet, so I don't know what he thinks.

  http://www.eclipse.org/technology/team-leaders.html

I have arranged a brief phone call with Paul Buck, Director of Eclipse
Development at IBM on Friday, May 2nd to discuss the idea.

  http://conferences.oreillynet.com/cs/os2003/view/e_spkr/1529

I would appreciate feedback before Thursday, May 1st if you would like to
see this happen. In particular, I need a specific list of benefits to Java
and Jython/Python programmers if they had full Jython/Python syntax support
and the ability to use Jython from with Eclipse. I have some general benefit
points, but I don't program in Java day-to-day so people on this list should
be able to give me better specifics.

Thanks,

ka

Re: [Jython-users] Project using jython as a scripting language

[Anthony Eden <aeden@si...>]

JPublish, a web application framework, uses Jython extensively to 
provide the glue between busines objects and the view layer (i.e. 
HTML).  You can find out more at http://www.jpublish.org/ .  For a 
desktop application I can point you to a couple which I have written and 
which can use Jython for scripting.  The first is the Universal Registry 
Client ( http://urc.sf.net/ ) which is a client for communicating with 
the different domain name registries.  Another is LogiTest ( 
http://www.logitest.org/ ) which is a web testing application.

I have also used Jython extensively in internal applications always with 
success.

Sincerely,
Anthony Eden

[Jython-users] Project using jython as a scripting language

[Aurelien Mazurie <aurelien.mazurie@fr...>]

	Hello to all,
	I'm looking for an open-source project in Java, using extensively 
Jython in order to add a scripting capability to the main program. That 
is, users of this program must be able to write some scripts in jython, 
and run thoses scripts within the program, to use his API and classes, 
and maybe external classes (written in Java or Jython).
	Does anyone know an example of this kind of project ? I'm looking for 
it because i can't find a real example of use of Jython (other than in 
a console, like with JExt, etc.)

	Thanks,

	Aurelien Mazurie
