Hi,

>    at

this is a bug that was introduced in 3.1.2, it should
be fixed in 3.1.4, please see 

http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/bridge/Util.java?r1=1.41&r2=1.42

The 3.1.2 standalone back-end selects the appropriate
channel and passes it back to the Apache or IIS
container (the fix was necessary for IIS).
Unfortunately the java.so did not pass the appropriate
logFile, which caused a null pointer exception.

As a workaround please start the standalone back-end
with a log file, as follows:


java -jar JavaBridge.jar INET:9267 3 JavaBridge.log

The appropriate /etc/php.d/java.ini file would look
like (remove the /etc/php.d/standalone.ini if it is
still there):

file /etc/php.d/java.ini:
---------------------
extension=java.so
[java]
java.hosts=127.0.0.1:9267
java.servlet=Off
---------------------

Hi Jost,

I created the problem report:
http://sourceforge.net/tracker/index.php?func=detail&aid=1518913&group_id=117793&atid=679233

However I am having troubles attaching a second file.

You gave me a couple options to resolve the problem.
1. Use TCP sockets.  How is this done?  Do you just configure
php.inidifferently?  Is there an example somewhere?

2. Use the servlet backend.  Don't I need to have tomcat running for this?
I currently don't run Tomcat, so this didn't seem like the option I would
like.

Thanks for your help.

Wendy

Hi Wendy,

> /usr/lib/jvm/java-1.4.2-gcj-1.4.2.0 java.java =
> /usr/lib/jvm/java-
> 1.4.2-gcj-1.4.2.0/jre/bin/java 

are you sure that the above binaries are 64 bit
binaries? On my installation these are 32 bit
binaries.

On Unix the usual build process creates a JNI library
libnatcJavaBridge.so. It is injected into the Java VM
to make unix domain socket communication possible. If
you build a 64 bit jni library for a 32 bit VM, the VM
will reject the library and the unix domain socket
channel fails.

As a workaround please use TCP sockets instead, or,
better, use the servlet back-end:

rpm -e php-java-bridge php-java-bridge-standalone
rpm -i php-java-bridge-3.1.4-1.i386.rpm 
rpm -i php-java-bridge-tomcat-3.1.4.1.noarch.rpm


However, this 64 bit jni and 32 VM problem is
something that autoconf should catch.  Can you please
open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the php-java-bridge-standalone and
php-java-bridge rpm files at the end of the ticket?

I will add an autoconf test to the next version of the
bridge which should solve this problem.


Regards,
Jost Boekemeier

Hi all,

I realized that rpmbuild --rebuild didn't actually install the rpm.  So I
found the rpm and have it installed.  I now am able to start
php-java-bridge.  I added the [java] section to my php.ini file and
restarted both php-java-bridge (standalone) as well as httpd.  SELinux is
disabled.

When I try to hit test.php I get the following error:
Error: The PHP/Java Bridge back-end is not running. Please start it and/or
check if the directory /usr/lib64/php/modules contains "java.so" and "
JavaBridge.jar". Check if the following values are correct: java.java_home =
/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0 java.java = /usr/lib/jvm/java-
1.4.2-gcj-1.4.2.0/jre/bin/java If you want to start the back-end
automatically, disable: java.socketname = /var/run/.php-java-bridge_socket
java.hosts = java.servlet = If that still doesn't work, please check the
"java command" above and report this problem to:
php...@li....

The back-end *is* running and the modules directory contains java.so and
JavaBridge.jar.  The java_home and java.java parameters are correct.

Any ideas?

Thanks!

Hi all, I am trying to install the php-java-bridge on a Fedora Core 5 64-bit
machine.  I have tried following various different instructions in the
INSTALL and README files trying to find the correct combination.  I have
upgraded my java-devel, php-devel, and php installations.

Can you confirm that the following command is what I want to do?

rpmbuild --rebuild php-java-bridge-3.1.4-1.src.rpm

This command gave lots of output and appeared to run successfully.  However,
I don't see if and where the bridge was installed.  (I'm pretty new to
installing packages on Linux, so this is probably just a misunderstanding on
my part).

# rpm -q php-java-bridge-3.1.4-1
package php-java-bridge-3.1.4-1 is not installed

# rpm -q php-java-bridge
package php-java-bridge is not installed


It looks like I need to follow additional instructions to move/edit files
however I don't know where the files exist.  Can someone point me to where
my install is, how to start the bridge, and what instructions I need to
follow next?

Thanks for any help you might be able to provide, I am looking very forward
to getting this working.

Hi Pat,

thank you for looking into this. Versions 3.1.2 and
3.1.3 indeed have a bug which might cause a crash on
Solaris and Windows; the java.c contains a new global
variable which was not properly initialized. On OS
which return uninitialized data for alloc_globals_ctor
(i.e. every OS except Linux), the bridge crashed in
rshutdown.

I have created a new download, 3.1.4 which should work
properly on Solaris. It also contains a java.so and
php-cgi, so the test.sh should now work on Solaris
x86, too.

I could prepare an update for 3.0.8, if you want it,
but I hope that this is not necessary, if 3.1.4 is
stable enough.


Regards,
Jost Boekemeier
