dynamically change page content

**Greyskull** · Jul 5th, 2008, 04:06 AM

Hello,

Im starting to learn a few things with JSP and here is my current situation:
I have several jsp pages linked together namely: header, menu, content and footer.
Each item in the menu should be associated with a different content i.e menu1content.jsp, menu2content.jsp, etc...
I have created an ant files to build and compile the jsp pages to a .war file and run it using Tomcat.
The question is, how would i do it so that whenever a link is clicked on the menu, the content of the page dynamically changes. i.e when link 1 is clicked it automatically assigns menu1content.jsp to the page?

Here is my main layout (baselayout.jsp)

Code:

<%-- Include common set of tag library declarations for each layout --%>
<%@ include file="/WEB-INF/jsp/common/taglibs.jsp"%>

<html>
    <head>
        <title>
            <tiles:getAsString name="title" ignore="true"/>
        </title>
    </head>

    <body>
	<div align="center">
	<table width="80%%" border="0" cellpadding="5">
            <tr>
                <td colspan="2">
			<tiles:insert attribute="header"/>
			<hr />
		</td>
            </tr>
            <tr>
                <td rowspan="2" width="20%"> 
			<tiles:insert attribute='menu' ignore="true"/>
                </td>
                <td width="80%"><tiles:insert attribute='content' ignore="true"/></td>
          </tr>
            <tr>
                <td width="80%">
			<hr />
			<tiles:insert attribute="footer"/>
		</td>
          </tr>
        </table>
	</div>
    </body>
</html>

im not sure whether ive explained this right but any help is gr8ly appreciated

Thanks,

use the <% %> tags to add add Java code to your page... Or read a little for more help

Thanks for the reply, i kinda knew i had to use the <% %> tags but not sure what to put inside it..anyways if it doesnt work how do i instead open another jsp page?

ive got the following set-up atm

Code:

<%@ include file="/WEB-INF/jsp/common/taglibs.jsp"%>

<div>
	<ul>
		<li>
			<a href="http://localhost:8080/HelloWorldTile">Hello World</a>
		</li>
		<li>
			link 2
		</li>
	</ul>
</div>

not sure what to put in link 2 which will open another jsp page which was compiled in the same war file unlike the first link which has a different war file..

thanks

you can use <% %> to write regular Java code.
Link 2 should be to were apache has mapped the web page, not the war file. War files are only containers (somewhat like jar files)
