Store data of other field of portal instance through service.xml and ext plugin

Step1-we have to create hook select custom jsp and select edit_instance and add some other field inside edit_instance

Step2-we have to create custom portlet for service.xml put field inside service.xml and build than deploy so table will be generated after copy that jar file from lib folder and paste inside tomcate lib/ext like this (D:\SEPTEMBER_TL\SERVER\liferay-portal-6.2-ce-ga2\tomcat-7.0.42\lib\ext)
restart the server and direct deploy of ext

Step3-we have to created ext plugin and  will put action class (from portal master) inside src full package
         like this src/com.liferay.portlet.admin.action/EditInstanceAction and goto inside EditInstanceAction and 1st get all field which we needed and than create object(create instance) set values and than update instance
(in ext there is one drawback when ever we modify action class we must have restart server)
