example

 void *handler= dlopen("libxxx.so", RTLD_LAZY);//open the so
 void *(*fun)(); //the definition of the fun pointer you want to call
 fun = (void *(*)())dlsym(handler,"fun"); // get the dynsym
 fun(); //call it

note: need check : handler != NULL && fun != NULL

you can get the dynamic symbol use readelf tool in linux

if you want call it directly from java code,it couldn't. because jvm dose not recognize it. but you can write a proxy so file which call the fun function in it.
