From PHP to JSP for a search-responder.php

Question

I have been asked to use the "search-as-you-type" solution offered up by Google at [http://code.google.com/p/search-as-you-type/|http://code.google.com/p/search-as-you-type/]. The documentation offered by Google is pretty much straight forward but of course the actual piece of code that gets the data is built in PHP and my client needs this to be used on a page serving up JSP.
I am learning JSP and moving from PHP and ASP and learning quickly but not quick enough to finish the project.
Would anyone be able and willing to help me convert the functions in the following PHP code into JSP?
Thanks in advance to anyone who takes the time to help me.

Thanks for your comment Gimbal2.
I have already been thoroughly surprised at how different JSP is from PHP. I am finding quite hard to wrap my head around the whole process to be honest.
I am beginning to see that JSP and PHP work in a totally different way than each other.
I am not technically trying to translate or convert the PHP file as much as I am trying to build a file in JSP that does the same functions. The main functions of the PHP script are commented by Google and should be easily enough re-written in JSP in order to produce similar results.
Since the output needs to be in a JSON format when passed to the .js file you'd think this would be better suited as a .jsp file as well or even a JAVA Applet, Servlet or even a bean. Since the whole site is already built in JSP for a multitude of other functions it seems likely that adding on more to read data from a source file and send it back to the .JS would be straight forward, but I could be wrong. But again I am not familiar enough with JAVA or JSP (yet) to make heads or tails of this.
1. // Adding a cache control so that browsers won't cache Ajax requests
2. * Get the sample data from the text file. @return array Loaded data
3. * Get the results based on user's query.
* @param string $query Query
* @param array $data Sample data
* @return array Result array
4. // Get the data and the query
5. // Build response
6. // Output response
