Including Files in JSP Pages

Concepts

• The include directive.

Including Files at Page Translation Time: The include Directive

    <%@ include file="template-example-footer.jsp"%>

• This will add the contents of the page in the file attribute to the JSP file at Translation time.

Simple Example of Including Files

• Since you can include the contents of other files when JSP files are converted to servlets, this allows us to create a simple template system for JSP.
• Example:
  • include-example-main.jsp
  • include-example-included.jsp

A Simple Template System for JSP Pages

1. Take a typical HTML page and slice it up into segments based on tags.

   

2. Put each segment into its own file.

   

3. Then replace each tag with a JSP include statement.

   

   Warning

   Don’t split a tag up into multiple files.

Example Code

• template-original
• template-example-main.jsp
• template-example-head-tag.jsp
• template-example-header.jsp
• template-example-content.jsp
• template-example-footer.jsp
