The installed base of Java VMs is substantially larger than the installed base of Python runtimes. So if you want to distribute your program, you have to include the Python runtime.

There are two *.py programs at Python's Vaults_of_Parnassus site, (http://www.vex.net/parnassus/) both which get stock quotes from the Yahoo.com web site, 'Quoter' and 'Quote'. My question is, does anyone have any information and/or documentation resources about the *.csv (comma seperated string) protocol as used by Yahoo.com as indicated in the URLs below? #Quoter, where 'stockstr' looks something like "SUNW+INTC+ORCL". reply = urllib.urlopen( 'http://finance.yahoo.com/d/quotes.csv?s=' + stockstr + '&f=l1&e=.csv').read() This apparently returns a CSV formatted string which is decoded back into the MS Excel spreadsheet. I only get win32com errors, and thus cannot get this program to work. #Quote, where 'symbol' is a single stock string like "FDGRX" reply = urllib.urlopen('http://quote.yahoo.com/d/quotes.csv?s=%s&f=sl1d1t1c1ohgvj1pp2owern&e=.csv' %(symbol)) (This apparently redirects to the 'http://finance.yahoo...' page similar to Quoter above, but it works) This returns a string like, '"FDGRX",35.55,"12/27/2002","5:59pm",-0.69,N/A,N/A,N/A,N/A,N/A,36.24,"-1.90%",N/A,"N/A - N/A",N/A,N/A,"FIDELTY GROWTH"'. This is then parsed into its component parts: Symbol, Value, Date, Time, Change, and etc. for a total of 17 pieces of information for each stock. Apparently this is all requested in the '&f=sl1d1t1c1ohgvj1pp2owern' part of the URL above. (?) My goal is to fire one query with a concantenated list of the stocks, (apparently like Quoter does above), and then parse and decode the returned comma delimited string into its constituent parts. Any help is appreciated, and I promise to put the finished product, including documentation, back to the web.

Basically i want to close the > IE window and i need to find the way either in Java or Jython I'm not aware of such thing - at least not from standard java. As java lacks any platform specific process control libs, you can't do that with the default api. I see two solutions to this: - don't use IE, but a java-based html renderer. Some other tools do that. - go and try a java-com-bridge like jacob and see if you get lucky with it. Regardless of wha you do - this subject is actually java-related, and has noothing to do with jython. Regards, Diez |

Hello- I'm new to Jython -- though I've been coding in Python for about 5 years -- and would like to use it to build some GUI applications for my users to access a Microsoft SQL-Server (we're running Windows XP on the desktops). I cannot find an example of how to connect via the zxJDBC libraries. Is this how I *should* be trying to connect and, if it is, can you show me "what button to push". I am using the ODBC Data Sources via the control panel, so I will have to connect hitting that. If there is an easier way to do it, I'm certainly willing to learn! Thanks! --greg ----------------------------------------------------------------------------- This message was sent using Conway Corporation WebMail -- www.conwaycorp.net |

There examples for zxJDBC on the jython website here: http://www.jython.org/docs/zxjdbc.html If you want to use the ODBC data source then you will need to use the JDBC-ODBC bridge driver. It's also possible to use the MS SQL-Server JDBC drivers. Let me know if you need more examples or have any other questions. thanks, brian On Sep 24, 2004, at 03:15 PM, yu...@co... wrote: > Hello- > > I'm new to Jython -- though I've been coding in Python for about 5 > years -- > and would like to use it to build some GUI applications for my users to > access a Microsoft SQL-Server (we're running Windows XP on the > desktops).

Hello- I have a simple java test where I'm using the PythonInterpreter to exec one statement: PythonInterpreter.exec("import myCPythonFile"). This goes through with no problem and jython is able to create the myCPythonFile$py.class file. So I package this functionality into a jar. I included the standalone jython.jar, and an application.jar containing: MyText.class, myCPythonFile.py. I execute this packaged test and get the following error: ImportError: no module named myCPythonFile. My question is whether the error is caused by incorrect python.path'ing or because jython can't create the myCPythonFile$py.class? The idea is to distribute the application with uncompiled cpython files.

If you place your .py file inside a .jar, you have to set python.path (by JVM start) or sys.path (from inside Jython) to the directory where your *.py files are, e.g. application.jar/parent_dir_of_myPyFile. As a shorthand, you could place myPyFile inside the /Lib folder of the standalone jython.jar, as described here: http://jython.extreme.st/talk/talk.html (search for Script Deployment) The standalone jython.jar automatically adds jython.jar/Lib to sys.path.

Dear all, I am not sure if the following is a trivial problem or not; thanks a lot for pointers in the right direction: I want to write a package in Jython, containing some helper classes and functions (class_foo.py class__1_foo.py ...) and finally a program program_foo.py importing and using the aforementioned classes. I want to start program_foo.py from another jython program, say main.py. - How can I run the file program_foo.py from main.py? - Will program_foo.py then find the import files in the same package or do I have to set additional environment variables? Maybe slightly off-topic: It would possibly also help if I could run a start.bat from jython. Is there a way to do that? Thanks a lot for your support.

Thank you for your reply. Sorry, I must give some more background information. Let's say main.py is a basic editor; I edit program_foo.py in main.py and want to start it from main after editing.

If you repeat the command: import program_foo nothing will happen. You have to do this: reload(program_foo) to re-import a module whose source file has changed. But this won't = re-load any other module that program_foo.py imported, so if those files = changed you still have a problem.

Well, in Python, there is a brute-force way of reloading all modules, and that is clearing out sys.modules dictionary. I wonder if that works in Jython. PS: There is also a safe way of doing it, which reloads only the modules that your program loads .. saving the initial sys.modules before your program loads and resetting the sys.modules to it when you need to reload the modules. Do tell me if it works. ~musically_ut On 8/1/07, David Handy <Dav...@sa...> wrote: > > If you repeat the command: > > import program_foo > > nothing will happen.

Both options for reloading a module work. The sys.modules version can also be done in a less radical style: After > del sys.modules["foo_module"] subsequent import of foo_module results in the import of the latest version.
