var reg = require('reg_java');
 
 
// get javaHome with version 1.7
reg.getJavaHome(1.7, function(err, data) {
    if (err) {
        console.log(err.msg);
    }
    if (data) {
        console.log(data);
    }
});
 
//get JavaHome from HKLM/SOFTWARE and ignore directories 
// [ microsoft', 'Classes', 'Wow6432Node/Classes', 'Wow6432Node/Microsoft'] while searching. 
/** if not use ignoreList operation of search will be very slow.
 
in the example: 
    ignored: HKLM/SOFTWARE/microsoft
    ignored: HKLM/SOFTWARE/Classes
    ignored: HKLM/SOFTWARE/Wow6432Node/Classes
    ignored: HKLM/SOFTWARE/Wow6432Node/Microsoft
*/
reg.search('HKLM/SOFTWARE/', 'JavaHome', function(err, data) {
    if (err) {
        console.dir(err);
    }
    if (data) {
        console.dir(data);
    }
}, ['microsoft', 'Classes', 'Wow6432Node/Classes', 'Wow6432Node/Microsoft']);
