I think it is too much open ended enquary. I do not know where to start? Of course, you can use Custom Tag in Tomcat. If you are using Tomcat look their sample example you will see simple custon tag example. Once you get started you will have many questions about TAG HANDLER CLASS, TLD, AND JSP. If need help then please come back again. BK
