Subject Re: Accessing a Tomcat webapp from a PHP webapp
Date Thu, 18 Feb 2010 21:51:12 GMT

Hi Chris!

>Interesting. What is the URL you are trying to access?
I tryed access a directory containing images. Each image is accessed
correctly, but the whole directory don't, generating the HTTP 404 status.

>Can you give us more details? 
I was using a AJAX request (using JQuery) to load the servlet content into
the page generated by the PHP script. 
I've moved the PHP script to an other machine (better configured) and now
the HTTP status is 200, but the response is blank... 
So, I've tested to use a IFRAME HTML tag instead the AJAX request and it
works... o_O 

>Also, if you can enable the AccessLogValve and post the log
file generated by that.
I've never used the AccessLogValve, can you help me? :)

>Where do you have Tomcat installed? Where is
your webapp application installed?
Tomcat is installed into my localhost and the PHP script is on an Apache
running into another host.

>Finally, please post your webapp's
entire web.xml file and all <Host> entries from conf/server.xml so we
can see what mappings are being used.
There isn't nothing special in these files - both are with only standard
configuration. (bad behaviour, I know). It's because still in a developing
enviorment... But here we go:
