Re: distributing jar files with distutils

Hi,

Thanks for the reply. You are indeed correct that it was a class loader 
issue. Digging a bit deeper I found my problem already has a bug report 
open for it:

http://bugs.jython.org/issue1373

As described on the issue I refactored SyspathJavaLoader a bit and it 
fixes my problem. However following the "how to submit a patch" 
guidelines leads me here:

http://jython.org/patches/

But I get a 404. Is the patch tracker down? Or are the patch guidelines 
out of date?

And about Jump it looks *very* promising. I will definitely be looking 
into that for distribution of my app. Thanks for the tip.

-Justin

Re: from and with keywords

Hi John,


Could you elaborate more on how you install Jython on your environment?
The first line looks like you are invoking jython from your default CPython instead of Jython.
The line 1: #!/usr/bin/python

Could you invoke Jython from your shell/command prompt with that setting?

Regards,
Daniel

Re: from and with keywords

Hello,

 

I unzipped the jython package and I can run the jython jar using java –jar jython.jar.  The interpreter works fine.

 

What the instructions lack is how to copy the jython jar and resources elsewhere.  I don’t want to ship the entire jython zip file with my project; I want to place the relevant parts into a war file.

 

The #!/usr/bin/python is irrelevant – it’s there because the script has it, but it still doesn’t work without it.

 

The answer seems to lie in the lib directory – could you tell me how Jython loads resources from it?

 

Thanks,

 


John

Re: from and with keywords

If you're deploying in a war, then stick the Lib directory in the "classes" dir (for example), and then point the python path at that directory with something vaguely like:

Properties props = new Properties();
String jythonPath = libDir.getFile().getCanonicalPath();
props.put("python.path", jythonPath);
PythonInterpreter.initialize(System.getProperties(), props, null);

In my case, "libDir" is a prop injected by spring:

<property name="libDir" value="classpath:Lib" />

So you'll need to grab the canonical path according to whatever framework you're working within.

Dunno if that helps?

pwd module on Windows

Hi,

What’s the best way to cope with these errors:

ImportError: pwd module not supported on Windows

If it’s not supported, what should I do to do something like this:

  currentuser= pwd.getpwuid(os.geteuid())[0]

I appreciate this isn’t really Jython specific, but I suspect someone has some thoughts on writing cross OS Python!

Thanks,

John

Re: from and with keywords

Yes you can (but that means you can only use java libraries, rather than python modules).  However your question was where to put resources -- and that's how I do it... ;-)

If you need to use the __future__ mod, you'll need to bundle the Lib dir.

Re: from and with keywords

I’m confused. J  So, what’s the difference between the Java libraries and the Python modules?  My understanding was that Jython makes use of the Python modules, shipped in the Lib directory.  And, my problem was that the Lib directory wasn’t in the jar hence the jar wasn’t portable (i.e. I couldn’t put it in a web app and use it). 

 

You seem to be suggesting that I can use the jar without the Lib directory bundled within it, and some other set of external modules?

Re: pwd module on Windows

And now I’m looking about for a solution, where by I need to check the operating system (I have other requirements to avoid running code that is platform specific – it makes calls to rsync etc.!), platform.system() returns ‘Java’, so it’s difficult to tell what is the underlying operating system.

 

Any thoughts?

Re: from and with keywords

Jason,

 

If I have my own library, that I’d usually point at through a .pth file in the site-packages directory, should I point to it through the python.path environment var?

 

I’ve just tried using the code sample below and it failed...

If you're deploying in a war, then stick the Lib directory in the "classes" dir (for example), and then point the python path at that directory with something vaguely like:

Properties props = new Properties();
String jythonPath = libDir.getFile().getCanonicalPath();
props.put("python.path", jythonPath);
PythonInterpreter.initialize(System.getProperties(), props, null);

In my case, "libDir" is a prop injected by spring:

<property name="libDir" value="classpath:Lib" />

So you'll need to grab the canonical path according to whatever framework you're working within.

Dunno if that helps?
