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

I can't get to work the get method of a HashMap, that I get from Java (i'm=
=20
not creating from php)

I try:

$Cliente=3D$h->get(1); //where $h is the HashMap


Also:

$i=3Dnew java("java.lang.Integer",1);
$Cliente=3D$h->get($i);
echo "Cliente:".$Cliente->toString();


both return :

*Fatal error*: Call to a member function toString() on a non-object.

Thanks Jost. Will try this out.

Yes, you're right, please see

p_i
d=3D117793&atid=3D679233


> renamed it to myapp.war

Please use the following workaround:

* switch off the override_hosts setting in your file=20
myapp/WEB-INF/web.xml:
<init-param>
<param-name>override_hosts</param-name>
<param-value>Off</param-value>
</init-param>

* copy the php-cgi.exe and all the dll's it needs into
the directory myapp/WEB-INF/cgi/

* create a file php.ini (in myapp/WEB-INF/cgi/) with
the following content:

extension_dir=3D"."
[java]
java.hosts=3D"127.0.0.1:8080"
java.servlet=3D"/myapp/PhpJavaServlet"

Yes. 1.5 should work as is, because the SEL policy
(please see the /usr/share/doc/php-java-bridge*/
policy file) contains settings for 1.5.

Which errors specifically?

It even works with gnu java, so I don't think this is
an issue.

Ah, could it be that you tried to install a i386 RPM
on a IA64 architecture?

Please leave them, they are there if one wants to use
custom versions of the JavaBridge.jar and
natcJavaBridge.so.  Please see the
php-java-bridge.sf.net page for the .ini
documentation.


> except that the os is FC4_x64 (amd).

That might be the reason. I think it should be
possible to compile the source rpm for AMD64. If not,
please file a bug report.

Jost Boekemeier

Can you please explain which setup you use?  Have you
started the backend via the php-java-bridge script or
do you start the backend automatically when apache
starts?

Jost Boekemeier

Hi Nicolas,

[hibernate]
> Can I use the bridge for this?

Yes.


> Do I have to install tomcat?

As I understand it hibernate is some kind of jdbc
driver. So unless you need tomcat for something else
(session sharing between php and jsp), tomcat is not
required.

> Is this possible? and stable?

Yes (for the PHP/Java Bridge part).

Please install libtool, too.  Please see the section

WinXP or Linux)" in the INSTALL document

Hi,

[please excuse the delay]

> puts them in
> /opt/mqm/java/lib 

Loading them shouldn't be a problem if the application
server knows about this directory and automatically
adds its content to the classpath. If not, then one
must find another way to load the libraries.

The recommended way to load libraries is to install
them as name-version.jar in /usr/share/java or one of
its sub directories and then require them with the
name and version number.

If you ship a servlet component, you can put the
libraries into the WEB-INF/lib folder, please see the
JavaBridge.war for an example. In this case you don't
need java_require().

Does it require an int or does it require a
java.lang.Integer?  I think this is a bug in the PHP
documentation which talks about "integer" and "float"
even though these are long and double.

Please see PR#1276004
(http://sourceforge.net/tracker/index.php?func=detail&aid=1276004&group_id=117793&atid=679233)
for details.

Since this is at least the third support request for
this, I'll add a "php longs are java longs" setting
for version 2.0.9.

I'll add your request to that ticket.


Regards,
Jost Boekemeier

Hi Jim,


> How can I tell?  My PHP file is from 6-29-2003.

With the command php --version or php -v.  php 4.4 was
released 2005, so I assume you have still the 4.1
installed.

Where have you installed php 4.4?  Please locate it,
check that it is a cgi binary (php -i must display
HTML content) and then copy it into the cgi directory,
please see section "AS/Servlet with PHP CGI" in the
README.


Regards,
Jost Boekemeier

Hi everyone !

I am having a hard time installing the brige. Yesterday I lost many hours
trying to figure out how to correctly install the bridge with java 1.5 on
FC4_i386 with preinstalled apache (v2.0.54) and php (v5.0.4).
I already installed it from source on RH8 and RHE 3, but I was also
installing apache and php, so it was really straightforward and without
hiccups.

So I have two questions : 

1) If I install the bridge from an rpm (i.e. FC4 i386), should I be able to
change the java.java_home and java.java from v1.4.2 to v1.5 java files ?
    I tried it but I had some strage errors about wrong parameters in the
Bridge... so I guess that the bridge is using some version specific stuff...
:(
    
2) After removing the bridge rpm, I compiled the source with java 1.5,
installed the 'service' link and the exec.
The phpinfo.php page shows that java is running, except that 2 fields are
null : 
   - java.libpath
   - java.classpath
putting them in the java.ini does not work.

The weird thing is that we were successful to install the exact same setup,
except that the os is FC4_x64 (amd).

Thanks !!

Francis Leblanc

Hi,

I am investigating php-java-bridge v.2.0.7 in order to assess its
capability to integrate PHP with "Enterprise" (read expensive) products
that only offer Java bindings, and elected to start by trying to connect
PHP 5.0.3 to WebSphere MQ on a Linux RHEL3 platform.

I am NOT a Java programmer, and am facing several hurdles - gaining
experience as I overcome them; but there are many things I still don't
understand so maybe my questions are silly.

When installing the client Java bindings, WebSphere puts them in
/opt/mqm/java/lib and I decided to "ln -s" all the jar files to
/usr/share/java ; now the bridge finds them easily without needing a
java_require() [I can't say I like this solution ... one would need to
hunt down the libraries of any product installed and make symbolic links
for all of them].

Following the manual I wrote a first PHP program that should put a
message in a queue and immediately retrieve it.

When I execute the script tough, after connecting to the Queue Manager
it needs to invoke the method=20
accessQueue(java.lang.String,int) and whatever I try I keep getting an
exception along the lines:

Fatal error: Uncaught [class java.lang.Exception: java.lang.Exception:
Invoke failed: [class com.ibm.mq.MQQueueManager]->accessQueue(class
java.lang.String, class java.lang.Long). Cause:
java.lang.IllegalArgumentException: java.lang.ClassCastException@74c3aa]

Apparently the bridge keeps converting the second argument (an integer)
to java.lang.Long while the method mandates an int.

Is there a way to overcome this problem?

Thank you
Massimo

I'm using php-java-bridge on RedHat Linux, and Java VM is launched everytime
Java program is called by PHP script.

Especially for the first time Java program is called since system boot, it
seems take much time to load Java VM.

Does anyone have any idea to save the loading time?    For instance, should
I launch Java VM as a resident process
or something?

I was thinking in use Java and Hibernate to persist my objects (defined in=
=20
java), and php for the user interface, everything in a windows server.=20

Can I use the bridge for this?

Do I have to install tomcat?, I want to use the java objects from PHP, but=
=20
no PHP from a java environment


Is this possible? and stable?


Thanks.
