Step2 –  Configure user- defined converter class in faces – config.xml file

<faces- config>



<converter -id>converter logical name</  >

<converter-class>fully qualified converter class</  >






Use. User- defined converter in both i/p and o/p UI Component

To use converter in i/p and o/p UI Components wl have to use the following tag

<f:converter conver ID=”–”/>

Where “converter Id” attribute will take logical name of the converter class which we provided in
