[Jython-users] Passing Arguments to the Underlying Java Session

[Robert W. <rob...@ho...>]

Folks:

How can I control the way jython invokes the Java vm?
In particular, I'd like it to invoke java as follows:

	java -Xmx1024m

because I'm creating huge vectors and I'm getting out of
memory exceptions.

Thanks in advance,

Edit the jython startup script.  The command "jython" is really a shell
script (jython.bat on windows) that executes Java with the appropriate
options and parameters.  Add the -Xmx1024m to the command in the file if
that is the option you need.

OR

simply invoke java directly:

java <java opts> -classpath jython.jar:<other stuff> org.python.util.jython myapp.py

Jython is, after all, "just" a java program (albeit a very useful
one).
