Javah error while using it in JNI

Question

Command:

javah -jni JavaHowTo

Result:

error: cannot access JavaHowTo 
class file for JavaHowTo not found

javadoc: error - Class JavaHowTo not found.
Error: No classes were specified on the command line.  Try -help.

I have set the class path correctly, but still i am getting this javah error.

Any solution for this will be much helpful.

Answer 1

Try

javah -jni com.example.JavaHowTo

where com.example is your package.

You also need to run javah from the directory containing com/example/JavaHowTo.class

e.g. if your structure is

/home/user/com/example/JavaHowTo.class

run javah from

/home/user
