Detecting system config (OS, memory, etc)

[John Lindwall]

Is there any simple way to collect OS version information from a Java Web Start application? To help us troubleshoot end-user issues we'd like to log the user's OS version (for us, a flavor of windows) including service pack info, build #, etc. The more detail the better.
It would also be nice to get the processor type and speed, memory size, etc.
Thanks!

hi John

is there any simple way

well, i dont think so. if u really want to get all information about a machine which seems running "windows" in your case then u can probably better look for a java product communicating with the system to get such information OR u could write a JNI program to get information via C/C++ and pass to the java program but just using simple java i don't think we can get all of that information...
tho simple information can be obtained via using System.getProperties() like,

import java.util.*;
public class MachineSpecification {
public static final String newLine = System.getProperty("line.separator");
public static String getMachineSpecification() {
StringBuffer sb = new StringBuffer();
Properties sysprop = System.getProperties();
sb.append(sysprop.getProperty("os.name"));
sb.append(newLine);
sb.append(sysprop.getProperty("os.arch"));
sb.append(newLine);
sb.append(sysprop.getProperty("os.version"));
sb.append(newLine);
return sb.toString();
}
public static void main(String[] args) {
System.out.println(getMachineSpecification());
}
}

anybody else?
also, i dont think this is related with Java Web Start. its just a regular java application. the only thing is, if u wanted to use some System Properties in the manner i have in above code then u'd have to sign the jar file for the application i believe...

Thanks for the reply. I felt this was relevant to Java Web Start in case there is some special JAWS API that I overlooked that might provide what I need.
The system props are not detailed enough for my needs. I'm starting to fear that I need to go the JNI route...
Thanks!

John,
I am really interested to know how you might do this, if you get a solution, please post it.
Thank you in advance
