Hi! You probably have a JDBC 2.0 driver. This means you have to add the jdbc-ext.jar (Something like that, it = should probably come with your JDBC Driver). javax.sql is an extension and not part of the 1.3 SDK. It should be part = of the J2EE SDK however (Try adding the j2ee.jar to your classpath).

I'm trying to load a JDBC driver programatically with jreload (without
putting it on the jvm's classpath when starting jython). When I try to
import the driver class I get a ClassFormatError, possibly suggesting the
thing I'm actually importing isn't really a class:
>>> import sys, jreload
>>> from com.ziclix.python.sql import zxJDBC
>>> ls = jreload.makeLoadSet('oracleLS',['pathToJar/classes12.jar'])
>>> from oracleLS.oracle.jdbc.driver import OracleDriver
Traceback (most recent call last):
java.lang.ClassFormatError: java.lang.ClassFormatError:
oracle/jdbc/driver/OracleDriver (Illegal UTF8 string in constant pool)
But, if I do the following:
>>> from oracleLS.oracle.jdbc import driver
>>> dir(driver)
It shows me that the class is in the driver package:
['ArrayDataResultSet', 'ArrayLocatorResultSet', 'BaseResultSet',
<snip>
'OracleDriver', 'OracleInputStream', 'OracleLog',
<snip>
'UpdatableResultSet', '__name__']
I have inspected this jar file and there truly is a OracleDriver.class in
the oracle.jdbc.driver package.
Any ideas what I'm doing wrong?
TIA,
Clark

Hello,
Only one questions:
Is following observations correct:
Whenever I execute PythonInterpreter.eval("something"),
I get back an instance of PyObject.
Whenever I call on this PyObject.__tojava__(java.lang.Object),
the PyObject is converted to the most derived java-type. (If such an element
exists)
Native Java types (e.g. int, short) are converted to its wrapper classes.
regards
Arno

You can do: a3 = array( [a1,a2], Object ) Or if that's not good enough: from java.lang.reflect import Array Array.newInstance( Object, [1,3] ) kb rpcee wrote: > > How do I use jarray.array to pass a 2D array, ie: > > a1=jarray.array(['a','b'], java.lang.Object) > a2=jarray.array(['c','d'], java.lang.Object) > > a3=jarray.array([a1, a2], zzz) > > what goes in zzz? > > or am I barking up the wrong tree? > > many thanks, Rich > > (apologies if its an FAQ I can't access it at present). > > _______________________________________________ > Jython-users mailing list > Jyt...@li... > https://lists.sourceforge.net/lists/listinfo/jython-users |

Then is what you really want to do something more like this?
globals = globals()
locals = {}
execfile( "cacheDir/a/b/scripts/plotTest.py", globals, locals )
???

So you want to do make each of the directories in your cachedir
into a python package - that means they need to have __init__.py files:
path = "pythonCache/a/b/scripts"
# ensure there are __init__.py files in each directory
# ideally, these would be in the source of the cache...
while path:
try:
open( os.path.join( path, "__init__.py" ), "wa" ).close()
catch IOException, val:
print "unable to create __init__.py in", path, val
path, dir = os.path.split( path )
import pythonCache.a.b.scripts.plotTest
pythonCache.a.b.scripts.plotTest.printHello()

Yes I got that to work but I want to specify the complete package
on the import line. this is because there can be more than 1
plotTest.py module in the sys.path.
So taking your code I want to do something like:
cachedir = "pythonCache/a/b/scripts"
if cachedir not in sys.path:
sys.path.append( cachedir )
import pythonCache.a.b.scripts.plotTest
pythonCache.a.b.scripts.plotTest.printHello()
to make sure I get the correct plotTest module.

sys.path shows where to look for Python packages (like the java classpath
shows where to look for Java packages). Thus, jython
looks in the scripts directory for a pythonCache package containing an 'a'
package containing a 'b' package containing a 'plotTest' package, and
doesn't find it.
Thus, I think you meant:
cachedir = "pythonCache/a/b/scripts"
if cachedir not in sys.path:
sys.path.append( cachedir )
import plotTest
plotTest.printHello()
Note, however, that the requirements to be a Python package are different
from
the requirements to be a Java package:
a Python package is a .py file or a directory containing an __init__.py
file
a Java package is any directory containing a Java class or containing a
Java package

Do you do: jythonc --deep --core --jar ? (I think the --deep option is implied by --jar, so you might ommit that) -- Vennlig hilsen Syver Enstad |

We're downloading jython modules from a server as the user requests them.
Since the modules can live in different directories on the server
we would like to keep the same directory structure on the client.
So the plotTest.py file get downloaded to the pythonCache/a/b/scripts
directory off of the current directory.
I've tried the following code snippet to import the module but I can't
quite get it to work:
try:
sys.path.index("pythonCache/a/b/scripts")
except:
sys.path.append("pythonCache/a/b/scripts")
import pythonCache.a.b.plotTest
pythonCache.a.b.plotTest.printHello()
but I get
ImportError: No module named plotTest
what am I doing wrong here?
Thanks,
Mark

They say *different* things - Jython conforms to CPython.

Yeah, you're right -- from the Java docs: getTime public long getTime() Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. But Python says the same thing: (from http://www.python.org/doc/current/lib/module-time.html) time() Return the time as a floating point number expressed in seconds since the epoch, in UTC. And in Jython, it says that is is the same epoch >>> time.gmtime(0) (1970, 1, 1, 0, 0, 0, 3, 1, 0) >>> time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.gmtime(0)) 'Thu, 01 January 1970 00:00:00 +0000' This only deepens the mystery . . . -- mikeh |

I'm using an Java API that returns a java.util.Date object and I want to compare that value with the current time. According to the JDK 1.3 docs, Date.getTime() returns the number of miliseconds sence January 1, 1970. Apparently, time.time() in Jython does not: >>> time.time() 1.015358378608E9 >>> float(wItems[0].JobStartDate.getTime()) 1.015268088E12 Is this a bug? What is the epoch that Jython uses? Does anyone have a work-around? -- mikeh |

Greetings, This is probably a question that has come up before, but I cannot find the appropriate answer on the web site or the mailing list as of yet. I have a complex set of python classes with a Jython UI front end. When run interactively, everything is fine. When I run it in an application (using PythonInterpreter to set python.home correctly), everything is fine as well. However, I want to distribute the code as an applet. When loading the applet, an exception occurs: AttributeError: class 'visframework.test' has not attribute 'TestTransform' visframework.test is a module and TestTransform is a class w/in the module. It is used in the applet as part of its initialization. The test module contains several classes used to test the application. I cannot set python.home in the applet (it is against the applet security policy). So my question is essentially this: how do I (or can I) properly package the compiled (with jythonc) python source into an applet that can be distributed w/o assuming jython is installed on the client machine? Any help is appreciated. More details can be given if needed. Thanks. TJK |

The jython interpreter does generate bytecode directly and on-the-fly. However, to capture the full dynamic range of jython behavior (things like module reloading, the exec statement, and the like), jython uses a custom ClassLoader in the interpreter. Since jythonc is supposed to allow you to use jython in places where an actual .class or .jar file is required, and where a custom ClassLoader might violate security, jythonc creates actual Java source. As a result, jythonc is a little stricter about Java subclassing, and may also have trouble with dynamic things like generating a base class at run-time. >More generally: Is there any documentation available about how jythonc works? <shameless plug> The forthcoming _Java Essentials_ from O'Reilly has a chapter about jythonc, mostly from a user perspective, but also containing information about how it works and the generated Java source. </shameless plug> Hope this helps, Noel Rappin _________________________________________________________ Do You Yahoo!?

Actually, there is some hope for chdir in the JPE project. I finally got this to build last week (the stable-beta-7 build) and my second test was to see if I could use it to chdir from java by calling chdir in python. IIRC it worked. Building JPE was a bear but I have been corresponding with Frederic and he tells me the head CVS version (at least as of about last Tuesday) uses a new, cleaner build system. An unholy marriage of jython and JPE might bring interesting results in the future. For instance, a new os module similar to jnios could be implemented by delegating problematic calls to the CPython os module. Or, less seamlessly, you could just Another option is to use JPE instead of Jython, but as far as I can tell, JPE is much less seamless than jython; I doubt you'd want to trade jython for JPE in most cases, but if you are tring to write 'scripty' stuff using JPE directly would be great. -----Original Message----- From: Dinu Gherman [mailto:gh...@da...] Sent: Tuesday, February 26, 2002 10:46 AM To: Finn Bock Cc: jyt...@li...

I'll check soon if I really need chdir or if I can replace it somehow... In fact, what I'm trying to do is port the ReportLab toolkit to Jython, and chdir is what seems to prevent the test suite (and some tools and demos) from working. So, my frustration is maybe more with Java than with Jython and surely I should have better investigated the issues instead of showing my Java ignorance. Sorry for that! What I'd suggest is some sort of collection of "porting stories" (Python to Jython) and/or issues to expect when doing this kind of thing. I'm not sure the FAQ is the best place for that, but maybe I'm wrong. OTOH, maybe it is too much to ask from Python programmers to code in a Jython-friendly way? Well, at least it would be helpful to know where to expect potential pitfalls. What do people think? The good news is that many parts of ReportLab seem to be working ok, especially the vector graphics stuff (after fixing the list builtin function)!

Joshua, >I'm interested in learning more about how jythonc works. I see that it produces an intermediate file which is then compiled to bytecode with javac. > >A few questions come to mind: > >Did the creators consider using Java as an intermediate, rather than generating bytecode directly (OK, Java source code is easier to produce, but isn't it possible to compile non-Java directly to bytecode?) Iirc, the early versions of JPython compiled to java and did not incorparate a byte code generator. Current versions include a byte code generator. You can see the java code generated by the jython compiler by using an option to jythonc. >Why is the absolute path of the *.py file embedded into the generated *.java file, and thence in the bytecode? What use could that be, considering that we can certainly move class files around? This is to allow a __file__ attribute on some standard objects (ao. on modules). In case you need to move a *$py.class file around it is generally better to move the *.py file and recompile it. >More generally: Is there any documentation available about how jythonc works? Apart from the jythonc things on www.jython.org there is not much documentation. In case you know about compilers, the code is quite readable and object oriented to the bone. It also helps to be familiar with java's class file format. The parser is generated from a syntax description and it calls the later stages of the compiler using a visitor pattern with a visit method for every python syntax construct. One area that I don't quite understand it the compilation of local python variables to local java variables. It works great nonetheless. Regards, Ype -- |
