Re: [Php-java-bridge-users] Sending request object to servlet with file_get_contents

[<php...@li...>]

Hi Marta,

first of all, requestDispatcher.forward() lets you forward POST
requests. But I don't think this works with include().


Second: some application servers like Sun Java AS 9 have a very small
thread pool size. If you open a loop-back connection to the back end,
you risk to lock up the whole application server.

AS 9 pool size defaults to 5, which means that 3 concurrent user
requests *will* lock up your application server forever, if your
servlet opens a HTTP URL connection back to your application server.
Apache's pool is larger, it defaults to MaxChilds=150. Send it more
than 75 concurrent requests and it will stop responding forever.

So file_get_contents(localURL) or a loopback java.net.URLConnection to
the back end is not an option. Forget that.


If your JSP has been written properly, it separates the business- from
the UI logic. So it should be easy to call the business methods from
your PHP servlet as well. If not, your only option is to refactor the
JSP or to duplicate some of its functionality.

A third option (but rather lo-tech) is to ask the browser to deliver
the content of your JSP and to deliver it to your PHP servlet using
AJAX.
