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

Greetings!

How can I set up the runtime path when calling Java classes with 
php-java-bridge?
My Java class loads some files from the filesystem using relative paths, 
but when I instantiate them with the bridge, they'll look for files from 
the "/" base uri (I'm under unix/linux system)
How can I set the runtime path from where Java classes should resolve 
relative paths? It would be great if there could be a way to set it from 
the php-bridge...

For now, I've resolved launching the Bridge.jar standalone in the java 
classes path, but there could be a more elegant solution...

Thank you very much
Michele

Hi Verena,

we've tested against the beta version of jdk1.6. There
were some changes since then, so this might be the
case, please see the ticket PR1597124 for details

Hi Verena,

> > /opt/jdk1.6/bin/jrunscript -l php-intractive

There are two ScriptEngines available, one is
php-interactive and the other one is the "normal" php
evaluator, which requires the "<?php" prefix.

In any case, the log and error output appears in a
file JavaBridge.log in the current directory. One can
change this with the
-Dphp.java.bridge.default_log_file="" option (empty
string means log to stderr).

The difference between "php-interactive" and php is
that the former starts a Lisp/Scheme style repl, which
in turn needs the java_closure() primitive to function
properly. -- PHP was not designed for Lisp style
evaluation, so "php-interactive" is pretty much
experimental at the moment.

You should find the reason in the JavaBridge.log. Most
likely the java_closure() syntax is not available. It
is exported from both, the pure PHP implementation
"java/Java.php" and from the java.so extension.


However, 

  jrunscript -l php testfile.php

should work as it doesn't need java_closure().

I tried http://php-java-bridge.sourceforge.net/server/test/HelloWorld.java:

verena@dhcppc8:~/tmp> /usr/java/jdk1.6.0/bin/javac HelloWorld.java
HelloWorld.java:27: cannot find symbol

            String name = (String)

                            ^
HelloWorld.java:32: cannot find symbol

                            ^
2 errors

Did you develop this class with the RC of JDK1.6? Did the interface change?

OK, what I did:
 - compiling the php-java-bridge source on my Suse Linux 10.1 x64 box from the 
tar.bz2 file. The used JDK was SUN JDK 1.5.0_x. 
- downloading Java 1.6.0 RC from SUNs website and installed the rpm 
- copied JavaBridge.jar php-script.jar script-api.jar to the JRE 6 extension 
dir
- started /usr/java/jdk1.6.0/bin/jrunscript -l php-interactive
Now I got a php-interactive> command prompt.
Now I tried things like 
echo "test";
with and without the ;, with <? or <?php and so on, but always I got:
php-interactive> echo "2";
script error: Could not evaluate script

Is the problem that I compiled the bridge with a JDK 1.5 instead of 1.6? I 
tried 1.6 but there were some errors. If this might be the problem I'll post 
the compile errors here.

I tried jrunscript with JavaScript as scripting language and this worked, so I 
guess the JDK is ok.

Is some additional information needed? What could I do now?

Verena

Sorry, you've already written it. I was just looking at "On Linux" part and 
ignored the Windows/Solaris text, but there you wrote which jars are needed. 
OK, so this is solved.

Actually compiling the source rpm isn't so important, since compiling the 
plain source worked. The thing is, I tried to install the 
php-java-bridge-devel.rpm, what failed because of the failed dependency to 
php-java-bridge.

In the replay to one of my last post with the subject
"bridging from J2SE to PHP possible?" I got the hint to install the 
php-java-bridge-devel.rpm to achieve what I was looking for. If I would know 
how to get the bridge working without having the rpms installed but compiled 
from plain source, this compilation problem wouldn't be important.

Hello,

I tried to install the php-java bridge on my Suse Linx 10.1 computer via the 
source rpm.

dhcppc8:/home/verena/tmp # rpmbuild --rebuild php-java-bridge-3.1.8-1.src.rpm
Installing php-java-bridge-3.1.8-1.src.rpm
warning: InstallSourcePackage: Header V3 DSA signature: NOKEY, key ID be89e756
error: Failed build dependencies:
        php-devel >= 4.3.4 is needed by php-java-bridge-3.1.8-1.x86_64
dhcppc8:/home/verena/tmp #        

I have PHP devel package installed, but it is called php5-devel, so I tried 
rpmbuild --rebuild --nodeps php-java-bridge-3.1.8-1.src.rpm

It seems the php-dev isn't the problem, since 
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20050922
Zend Extension Api No:   220051025
seems pretty much like the output of phpize

But later the compilation process quites with the following error:
RPM build errors:
    InstallSourcePackage: Header V3 DSA signature: NOKEY, key ID be89e756
    File not 
found: /var/tmp/php-java-bridge-root/usr/lib64/php/modules/RunJavaBridge

Any ideas how to get rid of this? Any further information needed?

Verena

Hi Jost,

this sounds great, I'll give it a try.
