Does there exist a way by which i can use WMI clas

问题:

Hi i want to use WMI classes to find out the application and products information. But the problem is that i want to use java or any scripting language like python, javascript or perl. I have heard about JWMI, it may be an option. Can anyone help me regarding this???

回答1:

JavaScript and Java aren't the same thing.

JavaScript

JavaScript is available under Windows Scripting Host (WSH). With it, it is fairly easy to access WMI:

var loc = new ActiveXObject("WbemScripting.SWbemLocator");
var svc = loc.ConnectServer(".", "root\\cimv2");
coll = svc.ExecQuery("select * from Win32_Process");
var items = new Enumerator(coll);

while ( !items.atEnd() )
{
    WScript.Echo(items.item().Name);
    items.moveNext();
}

jWMI (Java)

jWMI is a small library to enable Java to make general WMI queries. It seems to be available here

It also seems easy to use (though I am not sure how powerful or complete it is):

String name = getWMIValue("Select Name from Win32_ComputerSystem", "Name");

WBEM (Java)

WMI is a Microsoft implementation of Web Based Enterprise Management (WBEM). There is also a Java implementation of general WBEM which will be at some level compatible with WMI.

This might be the most complete true Java implementation you're going to find. If your needs are above tiny scripting (such as implementing a WBEM/WMI provider), then you might want to look into this option.

For the scripting language: Download Scriptomatic 2.0 and let the wizard create WMI code for VBScript, JScript, Perl, and Python. Here is something similar for Powershell.

I have successfully used WMI through JACOB

回答4:

JInterop is a good option for WMI operations in java.

回答5:

You might want to check J-Interop too. Here's a nice example: http://www.vijaykandy.com/2009/09/windows-management-instrumentation-wmi-from-java/

回答6:

JWMI performing WMI operations by creating and executing vb scripts with the relevant queries.
I am using J-Interop which is an open source and a good option.
There are also JACOB, J-Integra and EZ Jcom.

回答7:

In order to perform WMI queries I recommend you my library WMI4Java.

It is very easy to use:

Map<String, String> wmiObjectProperties =   
    WMI4Java.get().getWMIObject("Win32_BIOS");
