Including JavaScript source code

The next two script tags incorporate the JavaScript source files tree.js and script.js into the page so

that functions contained in these JS files can be called from the page.

The chunk of JavaScript code between the <script> and </script> tags refreshes the window to

apply the styles of the CSS file specified by the Bean to the page, then adds functionality to

determine the number of results to return when searches are performed.

Including the JSPs that comprise the main template

The body of the page includes several other JSP pages that constitute the sections making up the

adminTemplate page. The first two pages included are the adminHeader and adminNavItems

JSPs. Another standard JSP action, the include tag, is used to incorporate the adminHeader.jsp

and adminNavItems.jsp files. The HTML table, tr, and td tags help to structure the layout of the

In the following piece of code, the JSP uses a JavaBean to query the request to determine if the

current navigation mode is the student home page. If it is, the studentHomeNavigation.jsp is

included in the page also. This piece of code demonstrates how Struts-logic.tld tags work. The

logic:match tag checks if the value of the navKey variable, which checks the request for the
