Search Engine are now a web site / app fundamental. If you don't have
one or dont bother offering "search this site" you look sad. If you
have one already and it does not work properly or very limited
and/or tries to do too much
( "http://www.javascript.com/"; or "http://www.docjs.com/"; )
I just looking Java Networking by Elliot Rusty Orielly 2nd Edition
where there is an example of using Swing HTML Document / Parser package
`javax.swing.html.*' to trawl through a web page and print the hyperlink.
That gave me a brillaint idea of implementing a poor mans search engine.
You could take this example as basis for a Poor man JSP search engine.
But may be I dont wanna invent the wheel for Nth time in this new century.
No if you forget about indexing words for now. I can see two methods
of doing this for JSP pages.
1) Look at File System and grab "*.jsp" using FileReader or something.
Effectively you are looking at raw JSP which have a mixture of Java
and HTML.
Pros:
you dont have to deal with security.
It goings to be fast on the same server
Cons:
Potentially mixtures of Java and HTML
Restricted to the web server.
2) Grab the JSP pages using a java.net.URL object effectively you
are surfing your web app.
Pros:
Most portable solution
Cons:
Big problem all web app have some form security built in. Usually it
either custom form based or (intranet wise) web app realm based.
How do U get your search engine to authenticate itself through its
own web app? This is important for ecommerce site were you want
to able list pages that are deemed protected resources.
BTW: Any one seen?
Linux Journal Archive for Issue 70 . Alternatively
see any of Reuven M. Lerners "At The Forge" articles
