JNI with packages

[stixwix]

Hi,

I have a java program using JNI that works fine when in the default
(none) package.
If I have a directory called test:
The java code sits in this dir and I compile it from here.
I then run javah which creates the header file in this dir.
I then ggc the c code from here.
- it's all fine.

But in the real world this should be in a package so lets say the java
code goes in a a sub-dir of test called child.
The java code sits in this child dir and I compile it from here.
I change dir to the parent test dir.
I then run javah -jni which creates the header file in this dir (the
header file is now called child_xxx).
I then ggc the c code from here (after editing for the new header file
name).
- I get java.lang.UnsatisfiedLinkError: at the line number that i
call the native method in my java code.
The shared object remains exported as it was for the first working
attempt and I load the lib in the same way in the java code.
What gives...?
Thanks,
Andy

Did you provide the fully qualified classname (i.e.
my.package.MyClass) when you ran javah? Did you make the appropriate
changes to the names of the functions in your native source file?
