PHP application not working on Glassfish + Quertus server

[ase...@gmail.com]

Hello all. I have an PHP application (codeigniter framework) and I'm forced to migrate it to a Glassfish Server. I configured it and installed the Quercus PHP interpreter into it. Simple test pages works fine. But my PHP app has some errors:

Message: 'num_rows' is an unknown method of false.
Filename: core/Loader.php
Line number: 1099

I think the Quercus is not able to interpret some Codeigniter functions.

More info: Glassfish 4.1 running on Ubuntu 15.04, Quercus 4.0.35, Codeigniter 2.1.12.

Thank you.

Why 4.0.35 though you can dowload official version 4.0.39?

It seems your DB query just returned false.  The real error will be at another location.

Hello Kaz. "num_rows" is not my DB query. It's a codeigniter database method.

See here: https://ellislab.com/codeigniter/user-guide/database/results.html

Thats why I'm pretty sure Quercus is not understanding Codeigniter's methods.

Isn't CodeIgniter using PHP database classes to implement its methods?  If your backend database is MySQL, Quercus 4.0.35 has no way to return the number of rows of a query result and 4.0.37 or later does, AFAIK.

Hello Kaz. I installed Quercus 4.0.39 and tried to run, but the same error occours.

Sorry that I could not help you.

Since your code tried to call the num_rows method on a false value, your query probably failed to return a valid result just before the error line.

Line 1099 of CodeIgniter's core/Loader.php does not look like calling any DB methods.  Probably a class that is specified in your configuration caused the real error.

I cannot guess what code is really trying to call num_rows.

It apparently indicates the error occurs while in CI_Controller's __construct.  I don't know why Quercus does not locate the real error line.  I would try with a simpler application to identify what is wrong.  Do you have such an application?

Hello Kaz. You are helping me a lot!

After you tell me that my query probably failed to return a valid result just before the error line, I tried to put some "echo" lines in my controller (login.php) and I figured out that one of the first lines (parent::__construct();) is causing the errors. I think my db queries was not been called so far.

Please see the attachments.
