Question

I used the following guide to get started, http://cnd.netbeans.org/docs/jni/beginning-jni-win.html.

But when I try to generate the header file using the command below

JAVA_HOME\bin\javah.exe -o
HelloWorldNative.h -jni
-classpath PROJECTS_ROOT\HelloWorld\build\classes
helloworld.Main

I get the following error.

Error: Can’t recover from an I/O
error with the following message:
HelloWorldNative.h (access denied)

Thanks in advance 🙂

Looks to me like you are standing in a directory where you are not granted write access when you run javah.

Edit: What if you specify a full path to somewhere you know you have write access?
