There are some non-squeak alternatives to be aware of:

BATJAC - a st like environment, written in itself and with many of the std
st like env capabilities
http://www.odysseyitc.com/batjac/

Talks2 - a st -> java environment - havent' used it though.
http://www.architur.de/talks2/

and
Bistro - a smalltalk->java/jvm tool.  Includes a squeak translator.
http://bistro.sourceforge.net/ (doesn't look very active right now)

and finally, FROST, a different approach based on running java within a
smalltalk image.  The most current work is at

http://sabine.canis.uiuc.edu:8080/Frost

Interesting possibilities.  If you decide to stick with the squeak based
approach, you should look at the Java Virtual Machine Debugger Interface
JVMDI or the higher level JDI.  These define the protocol for interacting
with a debug java runtime.
see http://java.sun.com/products/jpda/ for more info.

Subject: [Q] Command line session/ Java debugging


Hi

Is there something like OSProcesses or some code with FFI that I can open
a DOS-box under Windows and open a session with a command line tool
like a Java debugger.

I'm asking this because I'd like to check if something like debugging Java
programs from within Squeak is possible.

What I'm looking for are the implementation possibilites for the
following:

- edit Java programs from within Squeak (an editor could easily be
  based on a Workspace; I can build nice browsing possibilities)
- run javac
- run a debugging session: set breakpoints and collect information
  on running Java programs.

Does anybody have some ideas (even partial thoughts)?

Note: Why Windows? Answer: Because many people use it and it is not
feasable to install Linux everywhere. However a Linux-only solution
would be fine as well for the moment.


Thanks for your suggestions in advance.
