A DESCRIPTION OF THE PROBLEM :
I use the attach api which is in the tools.jar,it always throws the exception of java.lang.UnsatisfiedLinkError: no attach in java.library.path.I test the attach api on the linux platform and it works well. So i think it's the jdk6 for windows has bugs.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a Monitor.java file as below:

import com.sun.tools.attach.VirtualMachine;
import com.sun.tools.attach.VirtualMachineDescriptor;

public class Monitor {
    public static void main(String[] args) throws Exception {
        
        for (VirtualMachineDescriptor desc : VirtualMachine.list()) {
System.out.println(desc.displayName());
        }
    }
}

compile it with the command :
javac -classpath %JAVA_HOME%\lib\tools.jar Monitor.java

then run the application:
java -cp %JAVA_HOME%\lib\tools.jar;. Monitor

it can't run normally and it throws the exception as the following:
java.lang.UnsatisfiedLinkError: no attach in java.library.path



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It will show the running the VirtualMachine.
ACTUAL -
It throws an exception in the runtime.
