jythono code completion?

jlist — 2008-12-01T17:59:37

Eclipse code-completion works wonderfully for Java. I wonder if it supports code-completion of Java classes in Jython? Or, is there some other editors that support this? I have been using a Python editor for my Jython work and it knows nothing about the Java classes... ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

using telnetlib and its expect method in jython

ShamanMahmoudi — 2008-12-01T12:59:55

Hi, I am using the latest stable version of jython, version 2.2.1 and I am trying to write a simple telnet program. However, I am having an issue with the expect method in it. Here is my code: import telnetlib HOST = 'localhost' user = 'someone' password = 'someones password' tn = telnetlib.Telnet(HOST, 22) aa, bb, cc = tn.expect(['>>>'], 1) print aa print bb print cc And this is the error message: Traceback (innermost last): File "/home/qm/workspace/project000/telnettest.py", line 11, in ? File "/home/qm/jython/Lib/telnetlib.py", line 623, in expect File "/home/qm/jython/Lib/select.py", line 204, in cpython_compatible_select File "/home/qm/jython/Lib/select.py", line 54, in _getselectable TypeError: ("Object 'java.nio.channels.SocketChannel[connected local=/127.0.0.1:45293 remote=/127.0.0.1:22]' is not watchable", 88) What am I supposed to do? Keep in mind that it works fine in Cpython and also if I replace expect method with read_until method. But, expect is important for me because there are multiple matches that I want to do, and I do not know the order in advance. Thanks in advance! /edit With further investigation, I have found out that if I leave out the timeout argument, and run it will work. But as soon as I set the timeout, I get this error. Any hints on what to do? I mean this method must have been tested thoroughly before right?

SciPy with Jython

indian scorpio — 2008-12-01T09:11:40

Hi Has sciPy been ported to jython or is there a way to use Scipy in Java. If yes can anyone provide with a link of an example or anything for that... i.e demonstrating how to use it. Couldn't really find any...

Re: Syntax errors

Josh Juneau — 2008-11-30T02:37:45

Hi David- I will take a couple of guesses as to what is going wrong, but I cannot be sure because the code looks to be correct. My first suggestion is that in the first program you displayed, the last import statement is spanning two lines. This could be simply because of the way the email was formatted, but if not then it needs to be on a single line. Second, which version of the JDK are you using to compile this code? How are you attempting to compile, via IDE or command line? Hopefully your answers to the above questions can help us decide where the issue resides.

Re: Syntax errors

Jeff Emanuel — 2008-11-30T02:22:27

It appears you are passing Java code to the Jython intepreter. Try javac instead.

But anyway, they all fail (with errors), except the last one (testJythonWithMain). The MOST important test, which really really must work reliably, is testDirect. Currently it throws a NPE. Adrian

Hi Charlie Really, I have been trying to get again the error and now the procedure is going perfectly without errors. I don't understand since I have been making different trials. I am going to try to put the same conditions as in the previous case. If I am able to detect again the problem, I will send to the list. Meanwhile, forgot my previous email.

This means figuring out how to workaround serialization issues in b0 is probably unproductive as whatever problems are there will probably change. What would be hugely helpful and could keep this from breaking in the future is adding some test cases for serializing Python subclasses of Java classes. If you could reduce your code above and whatever else you'd like to have work from your application to a test case we can run from regrtest and add a patch to bugs.jython.org, I'll apply it as part of my Java integration rework for 2.5 and make sure it passes for the next beta.

Could you explain what you're doing when it doesn't show up? You call sys.path.append from the console in Netbeans and the jar isn't available? Are there any error messages?

Re: Using Jython from Java

Charlie Groves — 2008-11-28T06:12:33

You can do this with a PythonInterpreter as well as with the command prompt. If you import sys and call sys.path.append with the path to your libs through the eval or exec methods on PythonInterpreter, the sys.path for that interpreter will be updated. Ahh, looking through the changelogs, it appears JYTHONPATH wasn't added until after 2.2, but it seemed obvious enough that I thought it had been around forever. Unless you're using one of the 2.5 alphas or betas, JYTHONPATH isn't going to work. The python.path system property exists in 2.2 and earlier and will continue to exist in future Jythons. To set it from an Eclipse launcher, add -Dpython.path= to the VM arguments field in the arguments tab of your run configuration.
