php-java-bridge-users Mailing List for PHP/Java Bridge

Jost,

I tried you're directions below for extracting the "java.so" and 
"JavaBridge.jar" from RPM and copying them into the PHP extension 
folder(/usr/local/lib/php/ext).

  I get this error returned to the browser,

#!/usr/bin/php Please permanently activate the extension. Loading java 
extension now... java extension not installed.

I can't run test.php from a command line either, it can't load the java.so 
with similar error messages.

I added the java.ini lines to the php.ini.  PHP is running fine.

The .so and .war file are located in  - usr/local/lib/php/ext

The contents of the php.ini file is below...

RH 9.0
PHP 4.4.0

Thanks,
Jim

I deployed the JavaBridge.war  to a Tomcat/Apache server and when I browse 
the test page,
numberguess.php, I get the following error message in the returned web page,

java extension not installed.

PHP is up and running OK and so are JSP pages.

Where can I find a copy of the java.so?

I can't it install it from the RPM because Red Hat 9.0 doesn't have a RPM 
for PHP 4.4, so I had to build and install PHP 4.0.  By doing that when I go 
to install the java-bridge in tells me it can find a dependcy package php 
4.3.*, even though PHP 4.0 is installed.

How can I tell the bridge RPM install where to find the latest PHP install?
OR
How can I get this build to work?
          phpize &&  ./configure --with-java=/opt/IBMJava2-14 \   
--disable-servlet

I get an the following error message when trying to build with the above 
line,
cp: cannot stat 'acinclude.m4' : No such file or directory

Thanks,
Jim

4.4.0 - at least you can always ask new users to get latest version of
PHP to avoid bugs introduced earlier. I've tried to compile PHP myself
from CVS, but failed. And also I don't use any web-server - I want to
try mix of Java and PHP in standalone application.

Yes, sometimes. It will be nice if this application could detect
presence of PHP and link it dynamically regardless of PHP5/PHP4
differences and without additional path setup.

I like things like unzip and run. Like any lazy user I hate doing
things that could be automated or not intuitively setup by default.
Especially test-cases. =)

README is very long and contains a lot of information. Read 25k just
to find command line options (especially if there are not any) is a
waste of time. I thought it should be good for an application to
react on help/unknown cmd parameters to be user-friendly.

The bridge is not running under Tomcat or Apache - it is supposed
to be used for standalone application in my case. And yes - it is
windows.

I don't think it is easy, esp. for me. =) Probably It should be
easier to create a proxy Java object, which will call invokable
PHP functions where it needed. The problem is that I still unsure
if I've got the whole picture of this bridge and how to plug it
into Java application correctly.

I'm an idiot :) Indeed, I simply forgot that I had PHP5 active on my Windows
testing machine.

Thanks, Jost! - Sorry I bothered you.

Hi Peter,

[please excuse the delay]

Well, your GCC installation uses two different static
libraries for m32/64 but only one dynamic library. 
Depending on the processor architecture this may or
may not be a problem.  I have changed the message in
2.0.8RC5.

> know if it would work with gcc-4.0.

gcc4 should be able to compile the source. (other
distributions such as RedHat use gcc4 for a long time
now, so I don't think that this is an issue).

Hi William,

[please excuse the delay]

to the best of my knowledge this problem should be
fixed in version 2.0.8RC5. Please see the updated
INSTALL document for details.

Furthermore it should be possible to use the binary
RPM:

* Extract the "java.so" and "JavaBridge.jar" from the
binary RPM with the command:

  rpm2cpio php-java-bridge*.rpm | cpio -iduv

* Install PHP 4.3.2 or above and copy the "java.so"
and "JavaBridge.jar" into its extension folder.

* run the test.php with: php test.php


Regards,
Jost Boekemeier

Hi,

> Fatal error: Uncaught
> [o(Exception):"java.lang.Exception: 

In PHP4 the exception would be a warning which could
be suppressed with @

Example:

$null = @new java("java.lang.String", null);
$ex = java_last_exception_get();
echo "val: $null, ex: $ex\n";

The above code would display "val: , Object" in PHP4.

The above exception message ("Uncaught...") makes me
believe that you already use PHP5 or above.

First of all, thanks for his cool extension. I got it running within 5
minutes, and it works like a charm.

Except for one issue: I'm using it to run Lucene with PHP 4. Now, in certain
cases Lucene throws an exception, for example when the query parser can't
handle an invalid query. Then I get a message like

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed:
[o(QueryParser):"org.apache.lucene.queryParser.QueryParser@1f8c6df"]->parse(
(java.lang.String)o(String):"AND "). Cause:
org.apache.lucene.queryParser.ParseException: Encountered "AND" at line 1,
column 0. Was expecting one of:  ... "+" ... "-" ... "(" ...  ...  ...  ...
... "[" ... "{" ...  ... "] thrown in {/path/name} on line 37

I know there is java_last_exception_get(), but the fatal error occurs on
line 37, which is exactly where I call the (java) query parser, and then
script execution is terminated.

So, is there anyway to handle those cases gracefully (except for upgrading
to PHP 5)?

Thank you,

Michael
