Si, quell'ho fatto.

Ho letto tutto quel che c'era da leggere (almeno spero).
L'errore che ho in compilazione è:
building '_jpype' extension
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/python2.4 -c src/native/common/jp_objecttypes.cpp -o build/temp.linux-i686-2.4/src/native/common/jp_objecttypes.o

Ma spero di non dover mettere mano al codice C++.
