I know core java and I begin to learn JSP/Servlet thru' Head First Servlet and JSP. I want to knpw about Jasper. What is Jasper? Any links or online tutorial for Jasper for beginners. What is Eclipse? Please don't mistake me, I caome across these words frequently. That's why I'm interested to know what it is?
Since you're talking about JSP, with Jasper you probably mean the JSP compiler that is included with Tomcat. You don't normally need to know much about Jasper. Tomcat invokes it automatically behind the scenes to compile your JSPs.
Note: JasperReports is something entirely different than the JSP compiler included with Tomcat, although they both have the name "Jasper".
It's also entirely different from Jasper - ZX Spectrum Emulator - allows Java enabled browsers to run ZX Spectrum games Jasper - Java Class File Disassembler JASPER (Java Simulation of Protocols for Education and Research) and Jasper - a COM object that is able to read and execute code from existing Java classes and expose the classes as COM objects.
And those are just from the first page of googling 'java jasper'.
