2-use a JSF converter for your p:calendar component to handle date conversion:
--step 1--- put the following in your faces-config:
<converter>
<converter-id>com.blabla.SolarDateConverter</converter-id>
<converter-class>com.blabla.SolarDateConverter</converter-class>
</converter>
---step 2--- Create the converter class (com.blabla.SolarDateConverter) and implement "javax.faces.Converter" interface.
---step 3--- implement "getAsObject" method and do the date conversion in java code FROM date String submitted by the calendar component TO Date object and FROM jalali TO gregorian.
---step 4--- implement "getAsString" method and do the opposite actions of what you did in "getAsObject"
---step 5--- add the following line inside your p:calendar tag :
<f:converter converterId="com.blabla.SolarDateConverter"/>
