[Hyperic-hq-discuss] Failed to load sigar-x86-winnt

[Angelo G. D. <ag...@li...>]

Hi folks,

I´m new to Sigar development. I´m trying some stuff using Eclipse IDE. My development platform is Windows XP 5.1.  I´ve put Sigar.jar in Eclipse buildpath and set the java.class.library environment to the directory where  is the sigar-x86-winnt.dll.

Below is my code:

import org.hyperic.sigar.*;

public class Server {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		System.out.println(System.getProperty("java.library.path"));
		
		Sigar sigar = new Sigar();
	

	}

}

When I run the code above, the following exception is thrown:

Failed to load sigar-x86-winnt: java.lang.NullPointerException
org.hyperic.sigar.SigarException: Failed to load sigar-x86-winnt: java.lang.NullPointerException
	at org.hyperic.sigar.Sigar.loadLibrary(Sigar.java:172)
	at org.hyperic.sigar.Sigar.<clinit>(Sigar.java:102)
	at br.com.unimedbh.Server.main(Server.java:15)


Does anyone have any idea of what is going on?

Thanks in advance.

Angelo

You could try disabling sigar's attempt to load the library itself, see:

I prefer to use this line of code:

File executionPath = new File("");
System.load(executionPath.getAbsolutePath() + "/lib/sigar-lib/lib/libsigar-amd64-linux.so");

This assumes that you have a program directory with the jar and a lib directory with the sigar libs.

Mine looks something like this:
/var/opt/programs/monitor-test/Linux64.jar
/var/opt/programs/monitor-test/lib/sigar-lib/lib/libsigar-amd64-linux.so

I've created different build targets with different main classes for each platform i want to support. Then I change the strings in the code to point to the different libs to load.
