  public class SystemProperties {
  public String getRuntimeEnvironmentVersion(){
  return System.getProperty("java.version");
  }
  public String getRuntimeEnvironmentVendor(){
  return System.getProperty("java.vendor");
  }

   public String getVmVersion(){
  return System.getProperty("java.vm.version");
  }
  public String getVmVendor(){
  return System.getProperty("java.vm.vendor");
  }
  public String getVmName(){
  return System.getProperty("java.vm.name");
  }

   public String getVmSpecVersion(){
  return System.getProperty("java.vm.specification.version");
  }
  public String getVmSpecVendor(){
  return System.getProperty("java.vm.specification.vendor");
  }
  public String getVmSpecName(){
  return System.getProperty("java.vm.specification.name");
  }

  
  public String getRteSpecName(){
  return System.getProperty("java.specification.name");
  }
  public String getRteSpecVersion(){
  return System.getProperty("java.specification.version");
  }
  public String getRteSpecVendor(){
  return System.getProperty("java.specification.vendor");
  }

  
  public String getOperatingSystemName(){
  return System.getProperty("os.name");
  }
  public String getOperatingSystemVersion(){
  return System.getProperty("os.version");
  }
  public String getOperatingSystemArchitecture(){
  return System.getProperty("os.arch");
  }
  }

  2.JSP代码:
