I have a JSP Page and I want to pass an XML tag in that JSP page, which would return some JSP scriptlet value......which is something like this -

<taglib : tag>

<%getResult()%>

</taglib :tag>

Can u explain me how to implement that ? What all files do i need to modify or create ....do i need to create a TLD file ...........

Please explain the process and explain with some code if possible? Thanks
