I have hardcoded a valid alfresco username and password in order to make a valid session and print the values in the dialog window
Code:
// Start the session
// AuthenticationUtils.startSession(user,password);
AuthenticationUtils.startSession("test1","test123#");
out.println("User: " + user + " End User <br>" );
out.println(" Pass: " + password + " aConv: " + aConv +"<br>" );
out.println( CHAINES[lang][CHOOSE_FOLDER] + "<br>");
