I've read about Jython and run a few examples, and the ideas there look brilliant. The suspicion that comes with any product that has not received frequent updates, has limited documentation, and little media attention (all these exist, but in small quantity) is that the product is not mature, that it has strange bugs that I will be the first to find. So, can I ask a question that might seem strange on the Jython list: Is it mature? Does it provide all advertised functionality with no disastrous bugs? I can say this about CPython, I think. What about Jython? Thanks, Joshua Fox jo...@jo... http://www.joshuafox.com |

Hi Joshua, I can understand your suspicion, it is hard to believe that something like Jython could go undiscovered if it was really any good. But, it has. FWIW, at my company, we have developed a very large & complex body of software using Jython. It has been deployed at quite a few Fortune 500 companies, and it is working very well. We have encountered almost no problems with it. It really works, and the combination of Jython/Java is the best developement environment I have ever used. Finn and Samuele have done an amazing job of tracking new Python features, Jython is never far behind the current state of the art. On the rare occasion we find a bug, they have always been quick to provide a fix.

I actually have a more serious doubt about CPython than Jython. The CPython threading approach does not take full advantage of multiple processors as does Jython (and Java). I fully expect this to be corrected in the future but so long as we're looking at each other through keyholes... That reminds me... I want to examine JPE more closely. I do struggle with the choice pf CPython and Jython. I long for one solution. If the threading is redone in CPython and JPE lives up to my fantasy then it might be a Jython killer? There's probably a long list of reasons that that will not happen. Oh, I just saw a briefing on Java 1.4. The reflection speed is supposed to be several times faster. That might be a big help to Jython peformance. --- Joshua Fox <jo...@jo...> wrote: > I've read about Jython and run a few examples, and the ideas there > look > brilliant.

I use Jython daily, partly for developing scripts which benefit from access to exiting Java code, and partly to try out ideas which I later implement in straight Java. I am frequently amazed at how well it works and how easy it is to use with java libs. Other than wishing it were faster (and honestly, in my case it has more to do with wishing Java startup times were generally faster), I have no substantial complaints. ..Mike Sackett On Fri, 25 May 2001, Joshua Fox wrote: > I've read about Jython and run a few examples, and the ideas there look > brilliant.
