JSP pages can be written in any well-formed language, including XML, but they are usually written in HTML. In PowerBuilder, you create JSP pages using any of the page wizards on the Web page of the New dialog box, and you edit them in much the same way as any other HTML page. When you create a new Web page, the wizard gives it the extension .jsp by default instead of .htm.
Standard HTML elements, controls, and client-side scripts are available to JSP pages. In addition, JSP-specific elements are available in the development environment for editing JSP Web pages:
In the Page view, JSP standard actions and scripting elements are represented by icons showing the element’s delimiters. When you select a scripting element or a 4GL server-side event, Java is the only language available in the script editor.
