Hi there
I am trying to write a Java wrapper for some C libraries. I have
gotten most of it working except that I am not able to launch
programs from the C libaries. I have a standard C-shared object
library where I define a function using
JNIEXPORT int JNICALL Java_API_Mypackage_myfunction
(JNIEnv *env, jobject theObj)
{
fprintf(stdout,"Entered myfunction ...");
execv("/sbin/ifconfig",NULL);
return(errno);
}
which I then call from my java program by -
API.Mypackage n = new API.Mypackage();
int ret = n.myfunction();
System.out.println(ret);
However, this method does not result in printing out the ethernet
interface information as it should if the program had executed the
"/sbin/ifconfig" program. It just prints till the "Entered
myfunction..." part and then exits. ERRNO reports "number 2" which
is "no such file or directory" while I KNOW that it is there.
This is what I get -
[amlan@catbert jwrapper]$ java TestTheWrapper
Entered myfunction...
2
[amlan@catbert jwrapper]$
What am I doing wrong ??
Thanks in advance.
-amlan.
