Description
The 'os' is a simple service that provides series of convinience methods to obtain basic information about underlying operating system (OS) such as OS name and type, CPU architecture and number of CPUs. This service allows:

• Get OS family, name and type.
• Get JDK name, vendor and version information.
• Get number of CPUs.

Configuration
The 'os' service, unlike most of the xTier™ services, does not require configuration through XML and thus it does not have an associated XML configuration file.

Examples
The os service is simple to use and follows the standard way for accessing services in xTier™. The following code snippet illustrates the basic usage pattern for the 'os' service:

1		// Get the instance of xTier kernel.
2		XtierKernel xtier = XtierKernel.getInstance();
3
4		// Get the instance of 'os' service.
5		OsService os = xtier.os();
6
7		// Use 'os' service.
8		System.out.println("Full environment description: " +
9		os.getFullEnvDesc());
10		System.out.println("Number of CPUs: " +
11		os.getNumberOfCpus());
12		System.out.println("Linux? " +
13		os.isLinux());
14		System.out.println("Mac OS? " +
15		os.isMacOs());
16		System.out.println("Netware? " +
17		os.isNetWare());
18		System.out.println("Solaris? " +
19		os.isSolaris());
20		System.out.println("Solaris x86? " +
21		os.isSolarisX86());
22		System.out.println("Unix? " +
23		os.isUnix());
24		System.out.println("Windows? " +
25		os.isWindows());
26		System.out.println("Windows 2K? " +
27		os.isWindows2k());
28		System.out.println("Windows 95? " +
29		os.isWindows95());
30		System.out.println("Windows 98? " +
31		os.isWindows98());
32		System.out.println("Windows NT? " +
33		os.isWindowsNT());
34		System.out.println("Windows XP? " +
35		os.isWindowsXP());
36		System.out.println("Windows Server 2003? " +
37		os.isWindows2003());
38		System.out.println("JDK name: " +
39		os.getJdkName());
40		System.out.println("JDK vendor: " +
41		os.getJdkVendor());
42		System.out.println("JDK version: " +
43		os.getJdkVersion());
44		System.out.println("OS name: " +
45		os.getOsName());
46		System.out.println("OS version: " +
47		os.getOsVersion());
48		System.out.println("OS architecture: " +
49		os.getOsArch());
