Having trouble with including JNI library in netbeans

Question

[Sorry a newbie question - I am more used to writing large amounts of Solaris kernel and writing a JNI for the first time]
Guys,
I have a C library that needs to hook into the Java bean. I created a JNI library wrapper around the C library using swig/javah
and that went fine (using some of the examples/ref in this forum). The JNI library contains classes like SysInfoJNI created
by swig.
class SysInfoJNI {
public final static native int NAME_LEN_get();
public final static native int NAME_LEN_set();
I quickly wrote a standalone test program where I did
public class test {
// Load JNI Library
static {
System.loadLibrary("SysInfo");
public static void main(String[] args) {
SysInfoJNI siJNI = new SysInfoJNI();
I can compile and run this on command line doing
javac *.java
java -Djava.library.path=./ Sysinfotest
and it all works fine. Now I move this code to netbeans since I need to add some more code
and create a java->web project and pretty much transfer the code there. I add the libSysinfo.so
using the property->library->create option but netbeans still can't see the symbols coming
out of Sysinfo JNI library. I suspect it wants the class definitions. My question is how do I
supply that? swig didn't really crate a header file but it did create Sysinfo.java file. Do I
just copy Sysinfo.java in the src directory (ugly?) or is there a convention of keeping the
*.java files in some standard place (like /usr/include for C headers) and then what would be
the method to include SysInfo.java to my netbeans src so that symbols can be found.
Thanks,

Answer 1

OK, seems like I had some kind of mismatch between the library & classes.
The loadLibrary only had the name and I had the library in /usr/lib. After running
truss -f -t open /usr/tomcat6/bin/startup.sh >& tomcat.out
I could see the tomcat was finding the library but still reporting link error.
Recompiling the library and classes again and then placing the library
in /usr/lib and classes in the right directory resolved the issue.
So I guess the answer to my original question is that classes need to
be delivered as a jar along with the rest of the distribution while the
library can be delivered in /usr/lib as part of the system.
Appreciate the help and quick responses.
