What is the difference between JSP and JSPX?

JSPX file is nothing but an XML format for creating JSP pages. JSPX forces the separation of code from the view layer in different files. Javascript and XML are written in different files in JSPX whereas Java code and XML code are written in the same file in the JSP. Writing an XML format code is better in some cases than writing the native JSP. The XML code is easy to manipulate, errors can be rectified faster. Also, the JSPX file has a simpler syntax in XML than JSP pages. But, executing the logical or arithmetic expression in JSPX is difficult and hard. Dynamic content is more easily generated on the JSP page than in the JSPX file.
