Fatal error: jni.h: No such file or directory while installing jPype
Question
I am trying to install JPype on Ubuntu 13.04. I have Oracle Java 1.7 installed. But when I do so, I get the following error:
src/native/common/include/jpype.h:45:17: fatal error: jni.h: No such file or directory
Unlike a lot of similar questions on stackoverflow, the file isn't present on my system ie
locate jni.h
returns nothing. Yes, I have run sudo updatedb before issuing above command.

You have installed a JRE and not a JDK.
To compile JNI native code, you need to install a JDK, which comes with the appropriate jni.h header, as well as the OS specific headers.
When you do that, update your include path to
-I <path_to_jdk>/include -I <path_to_jdk>/include/linux

In fact, this is the correct package to be installed!
$ sudo aptitude install openjdk-7-source
$ sudo updatedb
$ locate jni.h
$ /usr/lib/jvm/java-7-openjdk-amd64/include/jni.h
