Hi,

You should learn the Servlet first. Since all the JSP files are compiled into the Servlet before it is executed on the server. Server compiles the JSP file into a java file and then into a .class file and then runs it as servlet on sever.

So, it is necessary to learn the basics of Servlets first. You can learn Servlets at our Servlets tutorials section.

After learning you should learn JSP. Please check our JSP Tutorials page.

Thanks
