[Php-java-bridge-users] Configuration and Classpath

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

I've sent this message before but it was a little off-topic in a thread tha=
t
I should have assumed closed when you help me to make my script work.

I'm sending my questions again, not to be persistent, but to be a little
more organized.

Two questions came up:

1)
When I run the install.sh script it overwrites my php.ini with the PHP/Java
Bridge configuration.
It does not bother me right now because I'm not using any special
configuration, but when I go on production I will need my php.ini file. The
problem is that if I append the lines of the php.ini file that the
install.sh created to my original php.ini, the extension just doesn't load.
Is there any consideration that I should take into account before merging
both ini files?


2)
In a previous email, Jost told me that PHP/Java Bridge does not care about
CLASSPATH variable, and here comes my problem. I have to implement an API
which uses some XML files for its configuration. The xml is loaded using th=
e
getSystemResource method of the ClassLoader, which looks for a certain file
on the classpath as I understand. So, how should I indicate where those
files are using PHP/Java Bridge?
Right now I just added the path to the conf/ folder to the CLASSPATH and
everything worked.

Thanks

Hi,

It doesn't do this if you php installation supports an
/etc/php.d/ directory. Please see the php --configure
help for details (php's configure, not the bridge
configure script).

The only thing the extension need is a

  extension=java.so 

entry.

Some older JDK may still read the CLASSPATH
environment variable. But since Apache discards all
environment variables and executes in a clean
environment you cannot pass it to the VM (if you want
to run the VM as a sub-component of Apache).


> getSystemResource method of the ClassLoader

It should find the resources in the standard Java
repository, which is /usr/share/java/ext or
/usr/java/packages/lib/ext.


> So, how should I indicate where those

Just modify the standard location using the
-Djava.ext.dirs=... option. If you want to pass this
option from Apache, use a wrapper script, please see
our FAQ for details.

BTW: Isn't that backwards? If you want to load
resources from a user dir, why don't you simply use
getResource() instead of getSystemResource()?

No problem. Thanks a lot for the help you're providing.

Ok... it took me a while but I finally got it working. It was one of those
time when you try hundreds of different things and by the end you don't kno=
w
if what you're trying you have already done it or not.
The thing is that my php.ini was loading the extensions from extension_dir =
=3D
"/usr/local/php/lib/extensions/" and the java.so was installed on
/usr/local/php/lib/extensions/no-debug-non-zts-20050922/
What I don't know is why it didn't work when I copied every file from
usr/local/php/lib/extensions/no-debug-non-zts-20050922/ to
/usr/local/php/lib/extensions/
Is there any way to change that installation path while configuring PHP/Jav=
a
Bridge?

Not even using putenv PHP function? Because I use that to configure some
Oracle stuff.

I saw the FAQ... does it mean that I should start Apache with apachectl -D
java.ext.dirs=3D/path/to/my/confs ?
I would rather work something out that did not envolve having to modify
startup configuration.
I'm using this to work with a java api, which would be a quite small part o=
f
a much larger application and would like to make it easier to deploy becaus=
e
most probably I won't be installing it.

Might be. I read something  like that, the problem is that  the
getSystemResource call is made from  the API I'm working with (which source
I don't have), and I have to work with that.

Hi,

> "/usr/local/php/lib/extensions/" 
>/usr/local/php/lib/extensions/no-debug-non-zts-20050922/

I don't know where the first, incorrect path comes
from . The no-debug-non-zts-20050922 directory is the
correct one.

> Is there any way to change that installation path

No. php does this automatically. You seem to have two
different PHP versions installed. One is patched and
uses lib/extension. The other one is the version from
which the development files came from. Just remove
either one and it will work.

> Not even using putenv PHP function? 

I think this is a general misunderstanding how the
environment works. Each process has its own
environment. If you use putenv, this will not affect
the oracle server nor any other process which has not
been started from this particular php instance. Since
the php instance terminates after each request (which
means that you must not start processes from php
instances anyway), the putenv procedure is pretty
useless (at least in a web environment).

No. If you want to start Java as a sub process of
Apache, and you want to pass your own options to this
sub process, you need to write a wrapper binary which
exec's java with the parameters you need. Please see
the RunJavaBridge wrapper (in the server folder of the
source download) for details.

Why don't you simply start Java via a system service,
for example via tomcat?

I tried placing my config files on:
/usr/java/packages/lib/ext
/usr/share/java-ext/
/usr/share/pear
and in the same location as the php file that loads the class.

I can't get it to work.

The API I'm trying to implement loads these configuration files using
ClassLoader.getSystemResource and I need to figure out some way to load
them.

Thanks again for your helpful advice. Apart from this I'm making big
progress with PHP/Java Brigde and it is being very useful.

which java VM do you use and what's the java.ext.dirs
setting?

That was the key I needed Jost!
Thank you so much.

Now the config files are being loaded by the API from the java.ext.dirs

I also successfuly compiled and installed PHP/Java Bridge on Solaris and
it's doing very well through the final development stages before going to
testing and production.

I really appreciate your help and patience.

Thanks again,
