Re: [Php-java-bridge-users] getting hold of HttpServletRequest obj as if php page was jsp

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

Jost - thanks for the informative reply.

I am running PHP in apache, and forwarding JSP pages (and the java  
bridge) through to Tomcat. So according to what you say below, that's  
not going to work well for me in any case.

However I tried to get  java_context()->getHttpServletRequest()  
anyway, just to experiment and see if that would get me anything  
interesting. Unfortunately that's raising exceptions:

<?php
     $request = java_context()->getHttpServletRequest();
     echo $request->toString();
     $uri = $request->getRequestURI();
?>

displays:

[o(String):"org.apache.coyote.tomcat4.CoyoteRequestFacade@1707653"]
Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke  
failed: [o(CoyoteRequestFacade)]->getRequestURI. Cause:  
java.lang.NullPointerException

Is that the expected behaviour, even considering I am forwarding the  
embedded php java() statements?

I have a feeling that I am going to need to implement my own  
HttpServletRequest in any case - why, because I'll probably be  
implementing what used to be full JSP pages as in-page modules within  
a CMS (Joomla or Typo3, probably). Thus the URLs of the new system  
will be a lot different to the old system (the CMS will use parts of  
the URL for its own navigation, which I won't want to pass through to  
our java backend), and I will probably have to construct "fake"  
HttpServletRequests to match what the backend is expecting.


Just out of interest, how would I get Tomcat to interpret the php  
pages instead of apache?
- Is there an easy way to implement this with our current setup (we  
have stock apache running php, passing jsp pages to Tomcat on port  
8080 with jk)?
- Can one pass php pages through to Tomcat using the same mechanism  
as for JSP?
- If so, would this cause much of a performance hit?


Thanks for any help
Cheers,
