Hi Lochana,
As per our offline discussion you could try the following:
<%
var systemProcess = require('process');
var parent = 'file:///' + (systemProcess.getProperty('
jaggery.home') ||
systemProcess.getProperty('carbon.home')).replace(/[\\]/g,
'/').replace(/^[\/]/g, '');
print(parent);
var file=new File(parent+'/test.txt');
try{
file.open('w');
file.write('hello!');
}catch(e){
print(e);
} finally{
file.close();
}
%>
Thank You,
Sameera
