Dear Ranchers,
I'm doing a project in JSP and MySQL. In each and every page, instead of giving the title for the html page, is there any way to put the title in web.xml, so that Even if I want to change the title, i can just edit in the web.xml, so that it can reflect other pages also..
Please help me with your enriched ideas.
Regards
Aravind Prasad

I create screen.xml files for this... one per-screen in, for example /WEB-INF/screens/documentation/contents.xml:
Now just use XPath to query what you need. I have a ScreenFactory object which creates a simple bean from the configuration. I also store 'fragments', CSS files, JS files and Meta data in here.

One simple way to do this is to create a context init param in web.xml and use that for your title.
Are you familiar with context-init params?

I'd avoid setting up something proprietary to do this.
Either use context parameters as Ben suggested, or if you need something a little robust, properties files with the JSTL fmt tags.

Context init params can be used in the EL via the initParam builtin map:
${initParam.pageTitle}
Setting one up in the web.xml is as easy as:

EL (Expression Language) is must configured in your web.xml file in order to using it jsp pages.
this url will help you to configure it.. ServletsWebXml

<title>
<% ${initParam.pageTitle} %>
</title>
You do not use <% and %> when using the EL.

Post your whole JSP (now that you've updated it) and let us know what line 4 is.
