I'm trying to build the python interface of the stanford NLP on Ubuntu 12.04.5 LTS.
There are two steps required, the first of which is:

1. compile Jpype by running "rake setup" in 3rdParty/jpype

When doing so I get the following error:

```
In file included from src/native/common/jp_monitor.cpp:17:0:
src/native/common/include/jpype.h:45:17: fatal error: jni.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1
rake aborted!
Command failed with status (1): [cd JPype-0.5.4.1 && python setup.py build...]

```

The error messages says I'm missing `jni.h`, so as suggested [here](https://stackoverflow.com/questions/15250536/installing-stanford-parsers-python-interface-error-command-gcc-failed-with) if I ran the command `dpkg-query -L openjdk-7-jdk | grep "jni.h"` getting `/usr/lib/jvm/java-7-openjdk-amd64/include/jni.h`.

I believe that means I do have `jni.h` on my system, so I'm very confused right now. What is causing the error? Can you suggest any fix?

Thanks for your help!

**A FEW MORE INSIGHTS**

Here is the instruction causing the error:

```
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/lib/jvm/java-1.5.0-sun-1.5.0.08/include -I/usr/lib/jvm/java-1.5.0-sun-1.5.0.08/include/linux -Isrc/native/common/include -Isrc/native/python/include -I/usr/include/python2.7 -c src/native/common/jp_class.cpp -o build/temp.linux-x86_64-2.7/src/native/common/jp_class.o

compilation terminated.

```

It's coming from the compilation of `JPype` needed for the python interface. I do not know why but it includes paths that I don't have in my filesystem (i.e. `-I/usr/lib/jvm/java-1.5.0-sun-1.5.0.08/include/linux`).

How can I configure these paths correctly?
