Dear Jpype Users,
I'm trying to access package/class inside my dmvpn jar. My code is below:
from jpype import *
classpath =
"/root/.m2/repository/com/cisco/srtg/model/artifacts/dmvpn/2.14.13/dmvpn-2.14.13.jar"
startJVM("/auto/client/libjvm.so","-Djava.class.path=%s"%classpath)
java.lang.System.out.println("hello world")
tunnel_int = JPackage("com").cisco.security.vpn.dmvpn.TunnelInterface
tunnel_Class = tunnel_int.TunnelInterface
tunnel_obj = tunnel_Class()
Error Output:
[root@sdn-linux-4 mohammem]# python3 hello.py
hello world
Traceback (most recent call last):
File "hello.py", line 15, in <module>
tunnel_obj = tunnel_Class()
File
"/usr/local/lib/python3.4/site-packages/JPype1-0.6.1-py3.4-linux-i686.egg/jpype/_jpackage.py",
line 55, in __call__
raise TypeError("Package {0} is not Callable".format(self.__name))
TypeError: Package
com.cisco.security.vpn.dmvpn.TunnelInterface.TunnelInterface is not Callable
Observations:
1. jvm loaded from the path
2. hello world msg printed
3. pblm in calling package
Can anyone please help me out in this case? your help is very much
appreciated!!!
Thanks,
Mohammed.M

Jpype 0.5 does not work with python 3.x. I am working on a new version that does, but it is not ready for release yet.

I am running JPype with the latest version of python. Look in the setup.py, there you have to set YOUR PATH to YOUR SYSTEM JVM. Then it all works fine! If it does with python3, I have no clue...

I am not familiar with DNS's scripting capabilities, but who knows what DNS
does to it's PATH?
LoadLibrary will follow the PATH to find the requested DLLs.
execute the following and it should give you a better idea :
import os
print os.environ['PATH']

Update.. the problem has been reduced to the following giving an error when
executed only within a callback of Dragon Naturallyspeaking (DNS):
import win32api
print win32api.LoadLibrary('MSVCR90.DLL')
produces error:
Traceback (most recent call last):
File "H:\NatLink\NatLink\MacroSystem\core\natlinkmain.py", line 712, in
start_natlink
print win32api.LoadLibrary('MSVCR90.DLL')
error: (126, 'LoadLibrary', 'The specified module could not be found.')
Seems win32api library lookup isn't working within DNS, and have no idea
why. As far as I know the callback is working in 32 bit mode compatible
with the python version installed, so dll lookup wouldn't be failing due to
incompatible platforms. Any suggestions appreciated.

Hi,
Have run into a problem with Jpype importation that has me stumped.
Running the import in a script from the command line does not produce an
error. However, when the script is run from as a plugin callback of Dragon
Naturallyspeaking (DNS), this error is reported:
File "H:\Python26\lib\site-packages\jpype\_jpackage.py", line 18, in
<module>
import _jpype
ImportError: DLL load failed: The specified module could not be found.
If I load the _jpype.pyd file directly using ctypes.PyDLL, this error msg
is produced:
print ctypes.PyDLL(r'C:\Python26\Lib\site-packages\_jpype.pyd')
File "H:\Python26\Lib\ctypes\__init__.py", line 353, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found
I have looked at the dependencies of _jpype.pyd using Dependency Walker, in
case a missing dependence is causing the above error message, and it
reports MSVCP90.DLL, MSVCR90.DLL, and IESHIMS.DLL were not found (though
command line import works fine as mentioned). Searching for these dlls in
\Windows and adding them to the path environment variable caused DNS
startup problems with its C/C++ compiler, perhaps because of dll version
incompatibilities. JAVA_HOME for locating jvm.dll is set to H:\Program
Files (x86)\Java\jdk1.7.0_17. Python version is 2.6 32 bit and it's
running in win 8 64 bit.
Any suggestions on how to get Jpype to load properly in this case would be
greatly appreciated.
Thanks
Jason

I am not aware of any method that would allow a 32-bit process to load a
64-bit DLL, or vice-versa (ok htere are ways, but they are extremely
convoluted and fragile).
Considering that all macs are now 64-bits (except for much older machines
.. on which you won't get java 6 anyway), is there anything preventing you
from switching to a 64-bit build of python ?

Thanks Steve,
Eventually I discovered that I'm meant to use libverify.dylib instead of
libjvm.dylib (or, as it seems, libjvm_compat.dylib in OSX 10.5).
However, I'm currently using a 32-bit compilation of Python, and the Apple
Java distribution is 64-bit only. I don't know whether this affected its
automatic use of the JVM, but this is all I get when I load it directly:
>>> jpype.startJVM('/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libverify.dylib')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jpype/_core.py",
line 44, in startJVM
_jpype.startup(jvm, tuple(args), True)
RuntimeError: Unable to load DLL

error =

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libverify.dylib:
mach-o, but wrong architecture at
src/native/common/include/jp_platform_linux.h:45
So apparently there's a 32-bit Java 6 distribution called Soy Latte
(http://landonf.bikemonkey.org/static/soylatte/), but as yet, I've not got
it working:
>>> import jpype
>>> jpype.startJVM('/Users/joel/Downloads/soylatte16-i386-1.0.3/jre/lib/i386/libverify.dylib')

Now that I know it's an architecture problem, at least there are a few
things I know I can do, but for the moment I'm going to do any JPyping on
another machine.
Thanks,

Hi, JPype was looking like a good solution to my Python-Java interfacing needs, but then it refused to load some classes I needed. It turns out JPype was happily loading Java 1.5 classes, but failing for Java 1.6 classes with the same old "class not found" exception (which had me frustrated trying different class paths for some time). I have no problem compiling Java code importing these same classes. jpype.getDefaultJVMPath() returns '/System/Library/Frameworks/JavaVM.framework/JavaVM', which symlinks to /System/Library/Frameworks/JavaVM.framework/Versions/A/JavaVM, a binary provided by Apple. I assume JavaVM is meant to provide the current Java version, but it seems to not be doing that for JPype. It certainly seems as if everything else is set up for Java 1.6: $ which javac /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin/javac I would specify a more precise JVM path, but the Apple distribution of Java 1.6.0 doesn't have a libjvm.dylib, only libjvmlinkage.dylib which does not work as a JPype JVM path. Any hints? Thanks, Joel |

Hi Simon,
You're right, you don't need the java.lang stuff in CLASSPATH, but I do think you would need anything else.
As for running an AWT (or Swing for that matter) GUI application via JPype, I think that's highly risky and I wouldn't try it. The Java threading will likely cause issues. If you really need to do this with Python, you might consider Jython.
Sorry if I'm dashing your hopes for a quick solution with JPype, but the threading in Java GUI applications makes them a very "special beast". ;-)
Cheers,
Martin

Martin,
Thanks. Wow! That was a quick response.
There seem to be two issues:
1. > You need to make sure that ALL your necessary .jar files are in your CLASSPATH or else you get errors like the one you saw.
I am somewhat surprised, because awt is a basic part of the JVM/JDK is it not (package java.awt)? I clearly don't have to include everything, java.lang, for example.
java.lang.System.out.println("hello world") works out of the box. How do I know (a) which jar files I need and (b) where to get them from the System?
2. > If you use a multi-threaded Python application there is a strong possibility that you will hit a JPype bug
In my case, the Python code itself will be very simple. I don't intend to start up lots of Python threads. However, the Java does start up several threads (using SwingWorker), as this is a GUI application. Does your warning still apply?
Thanks in advance for clarifying.
Simon

Subject: RE: Problem with classes using AWT
Hi Simon,
Welcome to JPype! You've found one of the common problems in starting to use JPype. You need to make sure that ALL your necessary .jar files are in your CLASSPATH or else you get errors like the one you saw. JPype is not very helpful in telling you what's missing, so you have to guess, based on your knowledge of the Java code you're trying to access from Python. In your case you probably need to include all the appropriate AWT .jar files in your CLASSPATH.
Another caution for new JPype users: If you use a multi-threaded Python application there is a strong possibility that you will hit a JPype bug that can crash Python and/or the Java JVM. Such crashing is not guaranteed with a multi-threaded application but the likelihood of hitting it is increased. I've been struggling with this bug for years and have never been able to find the root cause and a fix. We suspect that it is some thread-safety issue in the 'C' level code that JPype uses.
Cheers,
Martin

Subject: [Jpype-users] Problem with classes using AWT
Dear All,
I am very new to JPype, but thought that it would be exactly what I needed to meet my needs.
BACKGROUND
For some time, I have been creating a tool to integrate GUI-based access to a particular type of database. The exact details don't matter. Suffice it to say that the idea is to replace the standard "File -> Open ..." dialog with "File -> Get from database ...", so that instead of popping up a file browser, we popup a database browser.
My mechanism is to create a platform-independent piece of Java code with a Swing GUI. I put the relevant .jar files in the classpath and then I should be able to call the code from any language/environment that has a "bridge" to execute Java. So far, I have demonstrated this principle using the scientific processing environments MATLAB and IDL and it works just fine.
For completeness, I thought I would try to call it from Python.
Browsing around, I found JPype, which (seemingly) should let me call Java from Python. I installed it without too many problems and thought I had everything sorted
>>> import jpype
>>> classpath = "... list of my jar files ..."
>>> jpype.startJVM(jpype.getDefaultJVMPath(), "-Djava.class.path=%s" %
>>> classpath) XMLU = jpype.JClass("xmlUtilities.XMLUtilities") <--- one
>>> of my classes
but then
>>> XND = jpype.JClass("xnatDAO.DAOConstants") <--- another of my
>>> classes
2012-03-09 13:29:40.407 Python[77031:60f] Apple AWT Java VM was loaded on first thread -- can't start AWT.

Does anyone have any ideas?

Hello, I was wondering if someone can help me with a problem I have implementing a java interface in python with JProxy. The problem is that the java method I want to use requires me to pass in an array of the objects implementing the interface, not just a single object. I can't figure out how to make a suitable JArray to pass in. Any ideas? Thanks, -- Richard Graham |

Regardless of the convenience or not to have this function that uses subprocess in the jpype distribution the patch adds too a way to work with the know locations using glob. Regards, Miguel Angel. |

I think that this solves your particular purposes and not the general needs of the Jpype library. IMHO calling subprocess from a library is a dangerous thing.

About if this is good idea or not i know it is not the fastest way to find out libjvm.so path but in many Linux machines i have tested i have Java installed and neither this machines have JAVA_HOME in environment not jre in LD_LIBRARY_PATH (i know i can fix in every machine but i want my software to be as autonomous as it can and have to create a .sh or change the environment in all the computers it have to works don't seems a good way to do it) so in this situations having a way to get the path directly from the java executable in the shell path it is better that fail. The file modified it is named _linux.py so i have not thought on FreeBSD, anyway if any of the programs it is not found the functions exists and the work to find libjvm.so path continue so i don't understand the what it is the problem, i have updated the patch with your fix, i have moved the function "_getJVMFromJavaBin" as the last resort and prefixed it with "if sys.platform.startswith("linux")", maybe anyone can add an "elif sys.platform.startswith("freebsd")" and write a better way to do it in FreeBSD or better still write a platform agnostic posix way to do it that i don't know, in the meantime any Linux users with this problem can use this patch.

This is portable to FreeBSD/Others (lsof?) ? . BTW I think that the _getJVMFromJavaHome and _getJVMFromLibPath are enough. If you will continue using the JavaBin A small fix to your patch: + proc = subprocess.Popen("%s &>/dev/null| %s -c java 2>/dev/null" % (java_path, lsof_path), shell=True, stdout=subprocess.PIPE) Greetings, -- Jorge Niedbalski R. -------------------------- |

Hi, i have added this patch request https://sourceforge.net/tracker/?func=detail&aid=3465996&group_id=109824&atid=655014 for a small improve in the way the libjvm.so path in linux it is detected, if anyone it is using JPype in linux with many different distros probably would be of help.
