Hi all,
I am totally new to jython/python. I just wanted to know if there
was anything available on the net for begineers in jython.
Any links to tutorials, sample codes, articles, intro, intermediate topics
like Activestate maintains for python. Something more than the docs that
come with jython. Also is anyone writing Full Docs just the one that comes
with Python.
Awaiting ur replies,
THanking you,
Jiger

<BR>유통 단계의 축소를 통한 매출이익의 증대라는 기업의 목적을 가장 이상적으로 접목시킬 수 있는<BR>새로운 마케팅으로 이미 1941
'뉴트리라이트'(현 Amway의 모기업)라는 회사를 통해 태동하여 <BR>발전을 거듭해 왔습니다.<BR><BR>초기 단계에서의 네트워크 마케팅은
일대일 마케팅 또는 'friendship marketing'이라 하여<BR>먼저 소비자가 된 사업자('독립사업자'의 개념)가 자신이 사용하고
있는 제품을 홍보하고 새로운<BR>판매원을 모집하는 과정으로 이루어졌습니다. 새로운 판매원의 모집에 대한 수당과 그들로부터 <BR>발생한 매출에
대한 보너스를 통해 '소비=사업'이라는 역설적인 상품유통철학을 실현하기 시작한 것입니다.<BR><BR>1950년대 스텐리(가정용품)를 시작으로
네트워크 마케터들에 의해 창업된 회사들은 메리케이애시<BR>(가정용품 및 화장품), 메리크로울리(홈 인테리어), 브라우이 외이스(타파웨어)
등으로 초기 <BR>네트워크 마케팅 회사들을 형성했습니다.<BR><BR>우리나라에는 91년말 '방문판매등에 관한 법률'제정 이후 암웨이,
뉴스킨, 허블라이프 등의 회사가<BR>진출해 활발한 시장점유를 이루어 냈습니다. 현재 200개가 넘는 수많은 네트워크 마케팅 회사를
통해<BR>오늘도 수많은 사람이 새로운 사업을 시작하고 또 그 보다 어쩌면 더 많은 사람들이 처음의<BR>꿈을 접고 포기하고 있습니다. 또한
수많은 사람들이 네트워크 마케팅을 통해 이미 경제적인 자유를<BR>얻었으며, 그보다 어쩌면 더 많은 사람들이 "난 사람을 설득하는 능력이
부족해" 라고 스스로 <BR>위로하며 중도하차하기도 합니다.<BR><BR>그럼 네트워크 마케팅의 성공요인은 무엇입니까?<BR><BR>그 어떤
성공자에게 물어도 그 대답은 하나일 것입니다. 보상플랜이 다르고 제품의 종류가 다르다 <BR>하더라도 여러분을 성공으로 이끌 단 하나의
단어.<BR><BR>그것은 '꿈' 입니다.<BR><BR>네트워크 마케팅 사업을 하면서 여러분은 자신의 꿈과 다시 만나게 됩니다.<BR>자신의
꿈과 다시 만나지 않은 채 혹시나 시작한 사업이 있다면 과감히 접으십시오.<BR><BR>"Build your dream
first!"<BR><BR>구체적이고 시각화된 꿈을 갖고 자신의 꿈이 이루어질 것을 믿고 다른 사람의 꿈을 이루어지게 <BR>하기위해 여러분의
네트웍을 건설하십시오. 네트워크 마케팅이라는 수단은 그 다음입니다.<BR><BR>초기 사업가들이 가장 쉽게 범하는 오류중의 하나가 바로
그것입니다. 마케팅을 이해하고 보상플랜에<BR>만족해하고 스폰서가 정말 나의 성공을 바라고 있다는 것을 알고 시작하지만 곧 자신의
<BR>파트너(Down-line)를 찾지 못해 초조해하고 시간이 흐름에 따라 후원하고자 하는 사람을 파트너가 <BR>아닌 자신의 그룹을 구성할
구성원으로만 생각하게 됩니다. 그때부터 자신은 그 사람의 성공 <BR>후원자가 아닌 자신의 그룹관리대상으로 생각하게 되는 것입니다. 다시한번
말씀드리지만 여러분은 후원하고자 하는 <BR>사람의 성공을 진심으로 바라고 있습니까? 사업적으로는 많은 대화를 나누면서 <BR>정작 그 사람이
어렸을 적 가졌다 지금은 포기한 꿈이 무엇인지도 모르고 후원을 하고 있을 수 있단 말입니다.<BR><BR>다시 네트워크 마케팅으로
돌아옵시다.<BR><BR>국내에 네트워크 마케팅이라는 단어가 생소할 때, 많은 사람들이 다단계 또는 방문판매로 인식하고 <BR>있었을 90년초에
한 외국 네트워크 마케팅회사가 국내에 진출을 시도하고 있었습니다. 물론 그러한<BR>정보를 먼저 접한 소수 그룹의 사람들이 사업설명회에 참석했고
제품설명을 들었습니다. 대기업 <BR>연구원으로 근무했던 ㄱ연구원도 그 사람중의 한명이었습니다. <BR><BR>ㄱ연구원은 자신의 가장 친한
동료였던 ㅈ연구원에게 소개했고 사업설명회 장소로 갔습니다.<BR>그러나 ㅈ연구원은 반 도 채 안차 있는 교육장을 보고 실망했습니다. 사람들이
이렇게 관심이 없는데<BR>자신이 어떻게 다른 사람을 후원할 수 있을까 고민하다 정중히 거절했답니다.<BR><BR>그러나,
<BR><BR>3~4개월이 지나고 그 교육장소는 항상 만원이었고 다시 많은 사람들이 거기서 분리돼 새로운 <BR>사무실로 독립하게 되었습니다.
처음에 초대되었던 그 사람은 앞으로 더 많은 사람들이 그 정보를 <BR>접하게 될 것이고 그 만큼 자신의 사업기회가 많다는 것을 알지 못했던
것입니다.<BR><BR>당신이 출근길 지하철안에서 신문을 통해 읽은 기사는 더이상 뉴스가 아닙니다.<BR>수백만 아니 수천만명이 이미 그 정보를
소유하고 있기 때문입니다.<BR><BR>정보는 일반적 관심으로 신뢰되지 않으며, 객관적 방법으로 증명되지 않는 특성을 갖고 있습니다.<BR>많은
사람들이 경험해보고 신뢰하게 되었을 때는 더 이상 정보가 아닙니다.<BR>국내에서의 암웨이 사업이 그 전형적인 예가 될

Yang,
to get exception information, you need to use the sys module.
sys.exc_info() will get you a triple. The third component of which is
a traceback object.
Using the traceback module you can then print out the exception stack
as you require.
Hope that helps,
Carl.

At a guess, I'd say you're using a version of Jython older than 2.1. Versions before 2.1 had no support for environment variables, which are pretty necessary for the cgi module... (and getting environment variables in Jython is just one more performance problem for the jython choice, but that's another story... :-) ) try 'jython cgi.py' in the jython/Lib directory, and look for the Shell Environment section. If it is empty, your jython version is too old, and you need to grab the new one from www.jython.org when SourceForge gets the files back up. If you are using 2.1, there is evidently another requirement for the cgi module to work. :-( kb Stephen Naicken wrote: > > Hi, > > I would like to write a cgi program using Jython as opposed to Python. > I know this has it's disadvantages regarding performance, but it's just > something I am playing with. > > When I submit a form to the Jython CGI program, it fails to get any > values (text input) from the form and the cgi.FieldStorage is None.

Hi, I would like to write a cgi program using Jython as opposed to Python. I know this has it's disadvantages regarding performance, but it's just something I am playing with. When I submit a form to the Jython CGI program, it fails to get any values (text input) from the form and the cgi.FieldStorage is None. Am I correct in saying cgi.FieldStorage() is not supported?

It's a bug in some 3rdy part classloader loading logic that throws a wrong expection when it should simply report that a class is not there. It is not directly Jython fault but Jython should be better prepared to deal with this or offer escapes. It is also possible that the new logic for relative imports in Jython makes it more vulnerable. We had a similar report from A.M. Kuchling, but we miss a bug report <wink>. Thanks, Samuele Pedroni. |

I now have a small jython file which shows the problem:
import sys
import java
import javax
=20
import pawt
=20
class Xtest(javax.swing.JApplet):
def init(s):
s.getContentPane().add(javax.swing.JLabel("Applet"))
#bag =3D pawt.GridBag(s.getContentPane())
#bag.addRow(javax.swing.JLabel("Applet"))
#bag.add(javax.swing.JTextArea("%s" % (sys.registry,)))
made a jar-file of it:
jythonc -d -a -j Xtest.jar Xtest.py
If the pawt package is imported the error occurs. If the statement is com=
mented
out, the applet works...
Is it perhaps related to the comment in org/python/core/imp.java, line 31=
:
// Simplistic implementation
// Some InputStream's might require multiple read's to get it all...
private static byte[] readBytes(InputStream fp) {

I know that too, but I am a bit pissed off that I can't have the shebang stuff on the OS that I am running without too much hassle. I once went to some length to get it to work on windows, something like this: --begin somepythonscript.bat-- @python -x %0 %* rem = """ goto :end """ # python code below here ..... .... --end-- But the rem line is outputted by the shell, and frankly it's pretty ugly.

Hi.
> Shouldn't the following be equivalent? I can't seem to get the jreload

No they are not equivalent. So the error you get is not a bug,
although I see what you want to achieve so see below.
> start jython with some.jar in cp, then:
>
> from org import somepackage
if I do:
import org
org2 = org
from org2 import somepackage
it fails, same story below.
> OR start jython with no classpath:
>
> import jreload
> ls = jreload.makeLoadSet('myls', ["/path/to/some.jar"])
> from myls import org
> from org import somepackage
> ImportError: cannot import name somepackage
from p.k.g import something
p.k.g referes to the packages namespace, nothing to do
with the current local/global scope.
from myls.org import somepackage works but - I know -
is not what you want.
If you know a point in the package hierarchy in your jar
that is disjunct from the hiearchy on classpath and sys.path
(NB typically org is not such a point <wink>), e.g.
org.iMnotToBeFoundAlongClassPathAndSysPath
org.empire.iMjustInTheJar
you can do the following:
import sys
import jreload
ls = jreload.makeLoadSet('someJarLS', ["/path/to/some.jar"])
sys.modules['org.iMnotToBeFoundAlongClassPathAndSysPath']=ls.org.iMnotToBeFound
AlongClassPathAndSysPath
sys.modules['org.empire.iMjustInTheJar']=ls.org.empire.iMjustInTheJar
then
from org.empire.iMjustInTheJar import somepackage
from org.iMnotToBeFoundAlongClassPathAndSysPath import somepackage
will work but
from org import iMnotToBeFoundAlongClassPathAndSysPath
will not.
Btw if you play the trick with a point not disjunct, you will get some major
troubles.
[Yup it is a hack, but the limitations of jreload come from the fact that it
allows
reloading, sys.path and classpath don't.]

Hi all,
I've got a problem with a jython applet which shall be loaded via
HTTPS. HTTP without the S works, no problem at all.
The applet is frozen with jythonc -d Haupt.py and then all needed jar fil=
es get
extracted to the jpywork directory. Afterwards the jpywork directory is j=
arred
into the applet.jar file. This file then goes to the server.
If I try to load the applet via am HTTPS server (CPython-driven slightly
modified m2crypto SSLServer or stunnel before the same server without SSL=
), I
get errors I do not understand. Somebody an idea?
The applet runs in Mozilla with the Sun java 1.3.1_01 plugin.
Traceback from plugin log window ("wird ge=F6ffnet" means opening):
Determine if the applet requests to install any JAR
Jar cache option: null
Jar archive(s): null
Jar cache version(s): null
Applet Installation finished.

One additional caveat: 5- close() doesn't give return process return code correctly - it should be something like: return self.process.exitValue() or None kb Kevin Butler wrote: > import java > import org > def popen(path, mode='r'): > r = java.lang.Runtime.getRuntime() > p = r.exec(path) > return org.python.core.PyFile( > p.getInputStream(), > p.getOutputStream(), > mode > ) > Note the following caveats: > > 1- PyFile is an internal class.

This is because of the wonderful naming convention of the getInputStream/getOutputStream methods :-) :
Process.getOutputStream() returns an OutputStream representing stdin (so you can write to the process's stdin)
Process.getInputStream() returns an InputStream representing stdout (so you read the process's stdout)
Process.getErrorStream() returns an InputStream representing stderr
This suggests you need to reverse the 'r' and 'w', and probably end up w/ something like this:
import java
import org
def popen(path, mode='r'):
r = java.lang.Runtime.getRuntime()
p = r.exec(path)
return org.python.core.PyFile(
p.getInputStream(),
p.getOutputStream(),
mode
)
f = popen( "echo hello" )
print f.read()
f.close()
f = popen( "cat" )
f.write( "This is\na test\nof write\n" )
f.flush()
for i in range( 3 ):
print f.readline(),
f.close()
try:
popen( "set" )
assert "Should throw IOException: CreateProcess "\
"because set is a built-in"
except java.io.IOException:
print "shell built-ins not supported, " \
"because we're not invoking a shell"
Note the following caveats:
1- PyFile is an internal class. It may change! Don't rely on it in code you expect to keep working later.
2- To get stderr, we'd need to do some wrapping of the stdout & stderr streams into one.
3- I don't think the mode handling is quite right. :-)
4- Shell built-ins don't work, because we're not invoking a shell
