Right Click on WEB-INF folder, New and choose File/Folder…     Another dialog box will appear, choose Other on the left pane and choose Folder on the right pane.

Let’s see how it works. Create 2 new JSP called JstL_Core_Tags_Redirect.jsp and Jstl_Core_Tags_Import.jsp. Add this to Jstl_Core_Tags_Redirect.jsp It is going to redirect the page back to index.jsp Add this to Jstl_Core_Tags_Import.jsp It will import or include index.jsp after Jstl_Core_Tags_Import.jsp loads. This is what we get when we run Jstl_Core_Tags_Redirect.jsp. Just type the address as shown in circled area and the page will redirect us back to index.jsp.     Interesting right? Well, do same thing for Jstl_Core_Tags_Import.jsp. Open browser then type the full address manually and we will get index.jsp is loaded after Jstl_Core_Tags_Import.jsp loads.

Create a new JSP file. Follow exactly the same way as we created the Jstl_Hello_World.jsp but name it Jstl_Core_Tags.jsp. Then we need to modify our index.jsp to contain the link to our newly created JSP. So please add below codes to our index.jsp just right after our first link to open the Hello World JSTL tags.   JSTL Core Tags JSTL if tag and EL operators   What we do here is basically to send some parameters so that they are accessible from the target page.   On the target page, we can retrieve these parameters via ${param.parameter_name} and we are going to use the logical JSTL tags to compare some values. Add below codes to Jstl_Core_Tags.jsp

3. Implementation of JSTL Core Tags First, let’s make a new JSP page. Right click on Web Pages folder, New and JSP…       Then a new dialog will show up as displayed above. Let’s call it Jstl_Hello_World.jsp. Then click Finish to create the jsp. Now we have 2 JSPs – index.jsp and Jstl_Hello_World.jsp.
