[Php-java-bridge-users] setting up php/java-bridge on tomcat

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

Hi,
I had a small problem setting up the php-java-bridge for Tomcat 7 on 
Ubuntu 12.04. I configured the bridge in the system wide web.xml. When 
testing the bridge I got this exception:
javax.servlet.ServletException:

The problem was that the ContextLoaderListener of the bridge tries to 
write a few files into the WEB-INF directory of the web app and by 
default the tomcat7 user has no write access to it. To fix it you just 
have to make tomcat7 the owner of the web app dir, restart the server 
and then change the owner of all files back to root. I didn't find 
anything about this in the docs so you might want to add a hint.

Another slightly strange thing is that the bridge creates a file called 
php-cgi.MISSING.README.txt when the sh wrapper and the system php is 
used, which I forced via the prefer_system_php_exec context parameter.
