We should provide a more userfriendly API to JPype. Currently users often report more or less the same kind of errors regarding classpath setup, jvm startup/shutdown and the like.
I started to write a Whitepaper for a userfriendly JPype API in the wiki (very early draft). Feel free to add your comments or enhance it as you like.
I would really like to add you all as maintainer of the pypi JPype1 package. Hence you would be able to release new versions without me.
If you could comment here with your pypi username (or create one if you don't have one) so I can add you :)
When I try to build on OSX, it fails with this error:

It works in earlier releases, but not the current HEAD.
I found that it would build successfully with the following:

JPype used to work without numpy, which transitively depends on a few native libraries that are not installed by default on my distros, viz.,
Since the addition of numpy JPype breaks on systems that don't have these dependencies. I see the error show up as ImportError: numpy.core.multiarray failed to import
.
Can we make the numpy dependency optional, and default to old behavior?
In my case, the folder /System/Library/Frameworks/JavaVM.framework/Versions/Current contains the folder 'Headers', while the folder /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK contains the folder 'Libraries'.
As a consequence, I have to set it like this:
def setupMacOSX(self):
self.javaHome = '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents'
self.jdkInclude = ""
self.libraries = ["dl"]
self.libraryDir = [self.javaHome+"/Libraries"]

"src/native/python/include",
]
Any idea why this is? Am I missing something here?
Hello,
I am trying to get jpype 0.5.4.5 working on Mac osx 10.9 (mavericks) with Java JDK 1.6 and python 2.7.5. The setup with python seems to work fine without any compilation errors. However, I get the following error when trying to use the module in python:

I'm not actually sure how the architecture is getting messed up. Any ideas?
Despite from being extremely slow these methods also leak memory. I think we should rewrite this stuff, we can only perform better...
The JNI interface calls doe not cleanup! E.g.:
==7783== 4 bytes in 1 blocks are definitely lost in loss record 5 of 1,320
==7783== at 0x4C2B6CD: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

Indeed leaking a few booleans seems to be not that bad. But consider a big double array!
Could this JPype package be uploaded to pypi? I'm afraid i dont know enough about pypi to help but I think it would be very nice to automatically download it with pip.
The following snippet does not work as expected:
import numpy as np
import jpype
jpype.startJVM(jpype.getDefaultJVMPath())
x = np.asarray([1,2,3]).astype(np.int32) # java uses 32 bit signed ints
b=jpype.nio.convertToDirectBuffer(x)
b.getInt() # outputs 16777216
b.getInt() # 33554432
b.getInt() # 50331648
I also noticed, that the test for conversion namely convtest.py is broken, since in Python2.7 the array module does not provide the buffer interface (anymore?!).
from array import array
a = array('i')
a.extend([1,2,3])
jpype.nio.convertToDirectBuffer(a)
cannot make memory view because object does not have the buffer interface
I would recommend using https://pypi.python.org/pypi/bumpversion/ to ease the release process a little. What do you think? I found out when reading https://hynek.me/articles/sharing-your-labor-of-love-pypi-quick-and-dirty/ which I can highly recommend.
If one enables the "-Xcheck:jni" option, the JVM (java7) complains about this:

Hi,
I am working with mscherer on a project using jpype. I tried to install jpype from a fresh clone from github. I discovered the in forums mentioned missing 'jni.h' file issue.
Apparently mscherer had started to fix this, but mixed two solutions. I changed locally this in setup.py
elif osx in ('10.7', '10.8', '10.9') and not os.getenv('JAVA_HOME'):
java_home = '/System/Library/Frameworks/JavaVM.framework/'
platform_specific['libraries'] = ['dl']
platform_specific['library_dir'] = [os.path.join(java_home, '/Home/lib')]
as it is mentioned in the
http://stackoverflow.com/questions/8525193/cannot-install-jpype-on-os-x-lion-to-use-with-neo4j
post. Apparently (at least in my MAC OS installation of 10.9.1) the folder
/System/Library/Frameworks/JavaVM.framework/
contains links to all current JAVA Versions. The subfolder Home points to
the home folder of the current JDK, which is the one needed for the jni.h
Maybe this helps! Best, JH
We should catch this case and display a proper message.
Hi,
just want to ask if somebody of our maintainers can provide binary packages (maybe wheel format?) for MacOSX to avoid need for a JDK?
Best,
Martin
in JPClass destructor the list of interfaces is being deleted. This may lead to undefined behaviour in other classes implementing one of those interfaces, since those wont exist anymore in a shared scenario. So we need some sort of tracking interface "refcount".
Maybe we should use smart pointers for that - which will require some work, but it seems to be the cleanest way.
Currently there is a tiny memleak, because the javatype map in JPTypeManger is not deleted.
I wanted to share with those interested that in order to get this work with anaconda I had to create a symbolic link in /usr/lib64 between libpython2.7.so and $ANACONDA_HOME/lib/libpython.2.7.so.1.0.
I was getting an error upon installation with an inability to find the python archive:
"/usr/bin/ld cannot find -lpython2.7"
This could possibly be corrected by allowing someone to specify the ld library search path during install but creating a symbolic link worked for me.
Hi,
since OpenJDK is licensed under GPLv2 with classpath exception, I wonder if its possible to include the headers of JNI in the repository. It seems that mixing GPL and Apache licensed code is only allow in one direction (what I've red so far). I must admit that I'am no expert in license questions.
But it would make the installation process very easy (especially for those mac users, who don’t read the documentation), since a whole JDK is not needed for installation anymore.
If it is not legal to include it, because the code is licensed under Apache, we might consider re-licensing under GPL?

As a heads up, I tried building last night with a system that didn't have Java so I installed Open JDK 7 and the build failed because it was looking in paths for a Java 6 installation.
I am not sure if you were aware, so I just wanted to let you know. It does not appear that a build will work with Java 7.
If this sounds like a surprise, let me know, and I can provide more detail. However, it should be very easy to reproduce by trying to build with a system that only has Java 7 on it.
@tcalmant reported via mail that he found jpype crashing in multi-threading environments. I put this here because I think it's better to have it publicly in the bug tracker than in emails :)

Now we only need to test this with the changes from #17. Sadly I can't reproduce the error myself as it seems. So help is appreciated! :)
not a blocker for a new release, but we should change this someday :)
We didn't notice that, because travis currently uses 2.7.3. But this will be updated soon. It seems it happens somewhere in finalization code. Thats the stacktrace in current Python:

After compiling JPype with MS VC 2008 Express I get
"the program can't start because MSVCR100.dll is missing from your computer" when executing the JPype testsuite.
I can fix it following the instructions here: http://stackoverflow.com/questions/6956747/c-sharp-missing-msvcr100-dll
Anyway, it would be nice if JPype would run out of the box or if I at least could find a note in the installation/user guide.
Starting with fd4153c I get a core dump after executing the testsuite.

Just noticed that installing from PyPI fails with the following message when trying to install on an Ubuntu Precise 32-bit system:
Please check that you have it installed. If you have and the destination is not
in the above list please consider opening a ticket or creating a pull request on
github: https://github.com/originell/jpype//usr/lib/jvm/default-java

/usr/java/jdk1.5.0_05
/usr/lib/jvm/java-6-openjdk-amd64
However, the install succeeds if pulling from master, presumably because of some new globs for finding JAVA_HOME?
Would you be able to update PyPI sometime soon with an update?
For reference, here is the place that I think is being used to manage Java installations on Ubuntu 32-bit Precise:

I’m using JPype to read some raw data from OLE2 files using the Apache POI Java library, and I have a question about data conversion. I am basically reading an array of bytes into a Java byte array (jpype._jarray.byte[]
) which I want to convert to a Numpy array. However, since the byte array does not seem to implement the buffer protocol, I have to resort to something like the following:
`numpy.fromiter(byte_array, dtype='uint8')`
Unfortunately this is quite slow when the byte array is large. As a work around, I tried using byte_array.__str__()
which is really fast, but I end up with a unicode string. This works when each byte is in the range 0-127, and otherwise the unicode representation seems to be different from the raw data (perhaps due to some kind of encoding?). Another approach is to use bytearray(byte_array)
which is also really fast, but unfortunately it only works if the bytes are in the range 0-127 (each byte is interpreted as a signed integer instead of an unsigned integer).
So my question is this: Is there a better way (i.e., quicker than using the iterator approach) to convert a Java byte array into a Numpy uint8 array?
Here's a small example:
nbytes = 2*1024**2
ByteBuffer = jpype.java.nio.ByteBuffer
bb = ByteBuffer.allocate(nbytes)
buf = bb.array()
for i in range(nbytes): buf[i] = (i % 256) - 128
# This takes 8.15 sec on my machine
a = numpy.fromiter(buf, dtype='uint8')
# This takes 11.2 ms on my machine
b = numpy.array(numpy.frombuffer(buffer(buf.__str__()),dtype='uint16'),dtype='uint8')
print a # the correct result -- but slow
[128 129 130 ..., 125 126 127]
print b # the wrong result -- but very fast
[196 197 199 ..., 125 126 127]
Thanks to all of your hard work, we are slowly turning into more than just the "friendly to install jpype fork", I initially started. Man this is so great..
Ok back to topic: it would be awesome to update the README and CHANGELOG to reflect all the changes.
I would love to do this, but I completely lost track of what you all did. So it would be really really wonderful if one of you people took the time to do all that :)

In setViaBuffer method,

Hi when I call
jpype.getDefaultJVMPath()
I get the following value:
'/usr/java/jre1.5.0_05/lib/i386/client/libjvm.so'
which doesn't exist on my computer, I use openjdk7.
all tickets blocking 0.5.4.6 are solved. push it to pypi ASAP
python3 has been released for a while,and it is good handling UTF-8 characters.

Hi,
if one converts 32 bit signed integer (default java int type) from python to JVM via jpype, there will be an integer overflow.
If one tries the same with 64 bit signed ints, the conversion succeeds.
I am on version 0.5.4.5 with java 1.7.0_51 (python and java 64 bit)
The following snippet shows the problem:
import numpy as np
from jpype import *
startJVM(getDefaultJVMPath())
a=np.zeros(10).astype(np.int32)
b=JArray(JInt)(a)
print a, b
# output [0 0 0 0 0 0 0 0 0 0] (51721472, 51721472, 51721472, 51721472, 51721472, 51721472, 51721472, 51721472, 51721472, 51721472)
a=np.zeros(10).astype(np.int64)
b=JArray(JInt)(a)
print a, b
# output [0 0 0 0 0 0 0 0 0 0] (0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
Hi,
The JVM lookup code in jPype seems to be too much hard-coded.
The getDefaultJVMPath() method should have a more similar behaviour on all systems, i.e. looking for the JAVA_HOME, then the predefined locations.
Also, it should not find in locations with a predefined JVM version number.
In my Python 3 fork of this project, I've written a more "JVM version tolerant" lookup, based on class inheritance, looking for a Java installation in the following order:
The commit is here: tcalmant@40a1b98
It should be easy to convert back to Python 2, as the only Python 3 feature I use is the relative import.
Cheers,
Thomas
(opt,) = get_config_vars('OPT')
os.environ['OPT'] = ' '.join(flag for flag in opt.split() if flag != '-Wstrict-prototypes')
'opt' must be checked for null values, otherwise the script may fail.
I just noticed we are missing a license. Which one would you prefer @DevilWolf? (http://choosealicense.com/)
You can find pretty decent JPype documentation at http://jpype.sourceforge.net/doc/user-guide/userguide.html
It would be nice to add it to the repo. As the next step we should convert it to rst and update it a little and make it available at readthedocs.
As proposed in #7, we need a more solid way of finding java's location throughout various *nix based systems and version (sun/oracle/openjdk).
If all else fails, we need to give the user an easy way to set it himself. Note that this has already been introduced with #10 by looking for the JAVA_HOME
environment variable. Maybe there are some other concepts we could integrate.
