[Jepp-users] installing issues

[V. B. <var...@gm...>]

Hello,

I would like to run python from java, I've found this sample class (last 
part of the mail) my main goal it to make this class usable. I use 
ubuntu 12.04. I added the jep.jar from "/usr/local/lib/jep" to the 
project as an external jar in Eclipse.
But when I run it it fails in this line "Main main = new Main();" with:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jep in 
java.library.path
     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
     at java.lang.Runtime.loadLibrary0(Runtime.java:823)
     at java.lang.System.loadLibrary(System.java:1028)
     at jep.Jep.<clinit>(Jep.java:138)
     at Main.<init>(Main.java:16)
     at Main.main(Main.java:32)

maybe I didn't set something properly, I've just installed python2.7.2, 
it works.
Then I followed these instructions:
https://github.com/mrj0/jep/blob/master/README.rst
I used this: 'pip install jep'
Furthermore, I downloaded the latest version of jep(3.1.0) from here 
https://sourceforge.net/projects/jepp/ too.

After this I should have set the LD_LIBRARY_PATH, and LD_PRELOAD 
according to the jep script (It was told on: 
https://github.com/mrj0/jep/blob/master/README.rst).
However, I have two of them (I set the second.):

the two jep script:
1, in the usr/local/bin, it says:
LD_LIBRARY_PATH="/usr/local/lib/python2.7/dist-packages/"; export 
LD_LIBRARY_PATH
LD_PRELOAD="/usr/lib/libpython2.7.so"; export LD_PRELOAD
2, in the downloaded_jep_folder/build/scripts-2.7, it says:
LD_LIBRARY_PATH="/usr/local/lib/python2.7/site-packages/"; export 
LD_LIBRARY_PATH
LD_PRELOAD="/usr/local/lib/libpython2.7.a"; export LD_PRELOAD

If i running the test "python setup.py test", I get the following output:

running test
jep runtests.py

That would be great if someone could help me.
