I realize, the potential to use the scripting engine with JVM seems far more deeper than what I initially thought. And thanks for freewheeling this discussion. As I see it, it is definitely worth a read for other people too because of your candid response. Thanks again. regards, jana Daniel,

In fact we do some of these things in ant ourselves, although some of the more complicated stuff we put in to scripts that we then trigger via ant. The reason I needed to use a scripting language was not because things could not be done in ant, but because I needed to start/stop servers as part of individual acceptance tests. For instance, one acceptance test checks that all of the Pulse startup options are correctly handled. It would not be practical to try to call out to ant from within a single acceptance test case. As you point out in your #6, Ant does have its limitations, limitations that would be solved by using a scripting language designed for the task. I hope that somewhat answers your question. :) -Daniel Hi Jana,

What kind of tasks would they be. Would I I able to classify them cleanly and make sure that box gets address with a clean bunch of python API's, when ever we perform systemic tasks before we perform Regression or any other form testing few things happen outside the intended context(am i sensible ?), 1)talk to Version control Management System 2)Do Compilation on the Source Code 3)Packing and Unpacking 4)Moving Files from one place to other, 5)Starting/Stopping Servers(Databases/Application Servers) 6)Executing Remote Commands(Ant goes down pretty hard here, this is one place where I see Ant cant do certain things if, we have to go outside the box to do certain things ,like perform scp, or starting a mysql server in a remote machine) I think I am slowly getting the picture. Thanks for the article. May be I should come back with more clarity and ask few more questions :-) jana Daniel,
Thanks for the response. What kind of tasks would they be. Would I I able to classify them cleanly and make sure that box gets address with a clean bunch of python API’s, when ever we perform systemic tasks before we perform Regression or any other form testing few things happen outside the intended context(am i sensible ?),
1)talk to Version control Management System
2)Do Compilation on the Source Code
3)Packing and Unpacking
4)Moving Files from one place to other,
5)Starting/Stopping Servers(Databases/Application Servers)
6)Executing Remote Commands(Ant goes down pretty hard here, this is one place where I see Ant cant do certain things if, we have to go outside the box to do certain things ,like perform scp, or starting a mysql server in a remote machine)

In fact, the implementation of the jython scripting support is a very thin layer around the existing jython interpretor. What the Java 6 scripting support gives you is a framework into which you can load other scripting engines, allowing you to run a variety of different scripts. By default, it will support at least javascript with the JDK. Jython, freemarker, groovy, jelly, jruby, ognl, velocity and others are all freely available.

I thought that even with Java 5, you could use Jython from inside Java programs.
