JSP Support 
Purpose
The PRT supports two ways of using JSPs in the portal:
· Declarative way
The JSP lives in the portal as a component on its own
· Programmatic way
Any portal component can access any JSP provided with its PAR file, or which belongs to another portal component
When a portal application uses a JSP resource containing double-byte characters, the portal runtime needs to know the character set that has been used to create the file. Thus the portal runtime can parse the file in the correct encoding and generates the corresponding portal component in UTF-8 encoding (or in any encoding specified in the runtime.doubleByteSupport.encoding property).
This is done by specifying the encoding in which the page has been saved in the pageEnconding directive of the JSP file:
<html> <%@page pageEncoding=”shift_JIS” %> ... |
