Date pickers

AUI Date Picker: 
To Use AUI we need to import: 
<%@ taglib uri="http://alloy.liferay.com/tld/aui" prefix="aui"%>
Then add your input field:

<aui:input type="text" name="datepicker" id="datepicker" />

Then add this script:

<aui:script>

AUI().use('aui-datepicker', function(A) {
new A.DatePicker({
trigger : '#<portlet:namespace/>datepicker',
popover : {
zIndex : 1
}
});
});
</aui:script>

Liferay UI DatePicker:
We need to import:

<%@taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %> 
Then add your input field:

<liferay-ui:input-date formName="dob" yearRangeEnd="2000" yearRangeStart="1950"
yearValue="1990" monthValue="3" dayValue="20" dayParam="d1" monthParam="m1"
yearParam="y1"/>



Jquery DatePicker:

To Use Jquery Date Picker we need to import

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">

Then add your input field:

<input type = "text" id="datepicker">

Then add this script:
 
 <script>
 $(function() {
 $( "#datepicker" ).datepicker();
 });
 </script>

Custom Landing Page Using hook Based On Role

Step 1:

Define portal.properties in WEB-INF/liferay-hook.xml.

<hook>
    <portal-properties>portal.properties</portal-properties>
</hook>  

Step 2:

Go to WEB-INF/src/portal.properties and define the following.

 login.events.post=CustomLandingPage


Step 3:

Go to WEB-INF/src and create new class "CustomLandingPage.java"

public class CustomLandingPage extends Action {

    @Override
    public void run(HttpServletRequest request, HttpServletResponse response) {

        try {
            String roleName =null;
            User users= PortalUtil.getUser(request);
            long []roleIds = users.getRoleIds();
            LastPath publiclastPath= null;
            for(long i:roleIds){
                Role role = RoleLocalServiceUtil.getRole(i);
                roleName = role.getName();
                
                if(roleName.equalsIgnoreCase("Role name")){
                     publiclastPath = new LastPath(StringPool.BLANK, "specific page path where page to land");
                     HttpSession session = request.getSession();
                       session.setAttribute(WebKeys.LAST_PATH, publiclastPath);
                       break;
                }
                
            }
        }
        
        catch (Exception e) {
        }
    
    }

Currency for all countries

Code to get currency symbol:

    Currency currency = null;
    Locale locale = null;
    String currencySymbol = null;
  /*Get List of available countries from liferay country table*/
    List<Country> countryCode = CountryServiceUtil.getCountries();
  
    for(Country country:countryCode)
    {
        try{
            locale = new Locale.Builder().setRegion(country.getA2()).build();
            currency = Currency.getInstance(locale);  
               currencySymbol = currency.getSymbol(locale);
              System.out.println("currency symbol is......"+currencySymbol);

            }
        catch(Exception e){
            System.out.println("exception..."+e);
        }
    }
