How to install Quercus on Linux with Tomcat 8

Question

I have a running Tomcat server and recently wanted to get phpmyadmin used with MySQL on Linux. I have researched a bit and found that Quercus can be used for PHP on Tomcat. I then started my installation.

I have downloaded the quercus.war, put it under /tomcat/webapps/ROOT, restarted tomcat, and tested on browser. However it's not working, index.php gives "PHP files are not being interpreted by Quercus" which I think it means failure.

I then searched and tried to put the quercus.jar (from quercus.war) under /tomcat/lib/ then restarted Tomcat. It gives the same page and same message with index.php.

EDIT: I have tried to modify /tomcat/web.xml, at the same time removed quercus.jar from /tomcat/lib and restarted tomcat. This time it gives HTTP 404,requested resource is not avaliable

My questions are:

1. Is there anything I missed or is there anything wrong?
2. Further, how do I install phpmyadmin after my installation of Quercus?

Answer 1

I decided not to use phpmyadmin and switch to VDBC. I put vdbc.war under /tomcat/webapps/ and restarted tomcat, everything goes fine now.

EDIT: I tried to put quercus directory under /tomcat/webapps/ and it works! However, I still cannot figure out how to make phpmyadmin run, is there any advice?
