Issue1269

The jython.bat delivered with jython 2.5b2 fails. I only get the output
from the java-VM what commandline parameter java understands.

I fear the handling of shell variables is not ok, i.e.:
echo %CLASSPATH% before the call of java with all arguments gave me:

c:\jython2.5b2\jython.jar;"=

echo %_JAVA_OPTS% gave me (german Windows XP):


ECHO ist ausgeschaltet (OFF).

Roland,

it works for me (see attached .log file).
Please let me know how you start it, and what goes wrong.
You might want to rem out the two @echo off lines (line 1 and line 8) in
jython.bat

Hello, had the same problem
fixed with (Line 163?)

if not defined _BOOT_CP set CLASSPATH="%_CP:"=%;%CLASSPATH:"=%"

surrounded the CLASSPATH-value with ""

Many thanks for the suggested fix !

Could you please provide a reproducible example of how it goes wrong ?

Sorry for being very carefully concerning quoting, but it is from
painful experience...

here is the output of the two relevant lines (with echo on):

C:\stuff\jython\jython 2.5b2>if not defined _BOOT_CP set
CLASSPATH=C:\stuff\jython\jython 2.5b2\jython.jar;.;C:\Program
Files\Java\jre1.6.0_07\lib\ext\QTJava.zip

C:\stuff\jython\jython 2.5b2>"C:\Program Files\Java\jre6\bin\java" 
-Xss512k  -Dpython.home="C:\stuff\jython\jython 2.5b2"
-Dpython.executable="C:\stuff\jython\jython 2.5b2\jython.bat" -classpath
"C:\stuff\jython\jython 2.5b2\jython.jar;.;C:\Program
Files\Java\jre1.6.0_07\lib\ext\QTJava.zip" org.python.util.jython

quoting might not be perfect, but working.
So I would be glad to see a not working example.

I call jython on my win32 box:
(I echo the line 164, marked with '*>>' )

I hope this all helps

And how I installed my jython:

rem Install Jython
rem
set PACK=packages/jython_installer-2.5b2.jar
set JAVA_HOME=C:\dev\java\jdk1.5.0_17
set JAVA_BIN=%JAVA_HOME%\bin
set PATH=%JAVA_BIN%;%PATH%
java -jar %PACK%

Now i got it - thanks - this helps a lot !

The error occurs if the environment variable CLASSPATH is not set at all.

Workaround could be:
  set CLASSPATH=.
(or to any reasonable value)

Huh, old bug discovered so late...

I need some time to fix this (empty-test CLASSPATH, and do the quoting
right).

thanks again,
Oti

fix is attached in 1269-patch (as a svn diff),
and checked in with revision 6086.

attached in issue1269-fixed.log is the output of some manual testing
with and without the --boot option, and with and without environment
variable CLASSPATH set.

IT WORKS: Thank you!
