Hi,

Yes, if your back end rejects the local fifo (in promiscuous mode), Java.inc
creates a new pair and tries again in the next request.

The fifos are only used on security enhanced linux, please disable them by
setting JAVA_PIPE_DIR to null.

Thank you very much for reporting this bug. -- It has been there since 5
years. I guess you are the first person who enabled promiscuous mode in the
back end w/o setting the host value in the front end.

Regards,
Jost Boekemeier

My /tmp directory ran out of space (or inodes or something) today.

When I went and looked, there were 350,000+ tmp files left over from  
the bridge, like:

-rw-------  1 apache    apache           0 Sep 11  
20:34 .php_java_bridge7ZE0oM
prw-rw-rw-  1 apache    apache           0 Sep 11  
20:34 .php_java_bridge7ZE0oM.i
prw-rw-rw-  1 apache    apache           0 Sep 11  
20:34 .php_java_bridge7ZE0oM.o

It actually ended up using all space on /tmp and killed my server!

I see that it's the php Java.inc file that's doing this. I see that  
the files are created, but never where they're cleaned up.

Not knowing much about how the bridge's life cycle works, I am a bit  
anxious to just start ramming code in there to clean up, but clearly  
there is a problem. Here's a graph of inode usage on my server since  
upgrading to the latest php-java-bridge:

Hi,

Version 5.5.2 now contains a try/catch (see
http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/server/php/java/servlet/ContextLoaderListener.java?r1=1.8&r2=1.9)
so that NoClassDefFoundErrors in Java 1.4 or below do not stop the shutdown
process.

Regards,
Jost Boekemeier

Hi,

* PHP/Java Bridge version 5.5.2 binary package is available for download:

Hi again,

I just saw that the cvs head contains a workaround for this problem.

To avoid this problem in version 5.4.4.2 please either upgrade to Java 1.6
or higher or never touch a running JavaBridge web application so that tomcat
doesn't have to restart it while running or remove the ContextLoaderListener
declaration from your WEB-INF/web.xml.

Jost Boekemeier

Hi,

> java.lang. NoClassDefFoundError

A simple file system copy operation may trigger this Java bug.

If cleaning catalina_home/Work and temp doesn't solve the problem, you need
to remove all .jar and .class files on this computer (yes, all of them) and
install java and tomcat again.

After that tomcat will work again, until someone copies .jar files or class
files around again.

There are several attempts which try to solve java's "dll hell", the best
proposal is the one from rice.edu, the most practical is the osgi package
system, while sun seems to favor its own breed for java 7.

Please do not copy jar or class files around after you have compiled a java
"program", until it is possible to link java modules to java programs. At
the moment Java has to search the computer file system at run-time to find a
class. If you modify the computer file system after the compilation phase,
Java may mix up class versions, causing strange error messages at run-time.

Jost Boekemeier

This error message means that php is not installed or php-cgi not in the
path.

Please install PHP. You can set the php.java.bridge.php_exec System.property
to specify a custom php executable path, for example:

java -Dphp.java.bridge.php_exec=/opt/PHP/bin/php-cgi

If you have Apache/php or IIS/php running elsewhere, you can copy you php
scripts there and use an urlConnection to execute them remotely, as shown in
the example you have given.

Otherwise please see the PhpScriptEngine documentation, it contains an
example.

You are calling a static method on an object, which you should not do,
as the method/procedure belongs to the class and not the object.


have you tried $PA = new Java("Pa.runme"); or something like this?

Hi,

Please use echo java_inspect($jobject) to see the contents of jobject. It
will list your method. If not, your class doesn't contain it.

> What does java_require do?
>>From what i understand it imports java archieves so that can use them

Not really. It may import classes, provided that these classes aren't
cached.

Yes, i mistyped. I meant to say i changed my require_once call(...) to:

require_once ("http://localhost:8080/JavaBridgeTemplate551/java/Java.inc");
Again, i am still stuck with the same issue of not being able to call the
feature.

Hi Jost,

i did as you said and changed the java_require call to:
require_once ("http://localhost:8080/JavaBridgeTemplate551/java/Java.inc");

I then copied my library into the WEB-INF/lib folder of the
JavaBridgeTemplate
file and then add my index.php to the folder.
However, the exact same thing happens. I can declare the instance of the
object, but when i try to call the method/procedure/feature it is a
no-can-do.

It tells me:
javax.servlet.ServletException: java.lang.RuntimeException:

[[o:Exception]:"java.lang.Exception: Invoke failed: [[o:PA]]->runme. Cause:

So the same thing is going on.

What am i doing wrong? This time i am using tomcat straight (as opposed to
using it through apache2).

Hi Matt,

Did you report the missing function yesterday?

If so, you're likely communicating with the wrong back end; it defaults to
/JavaBridge/.phpjavabridge.

Please either fetch Java.inc through
http://localhost:8080/JavaBridgeTemplateXXX/java/Java.inc or adjust
JAVA_SERVLET accordingly.

Runme is not a method, it's a procedure.

In Java procedures can be called using the same syntax as methods, but
that's bad style and eclipse will warn you about it.

Hi,

[Just a quick reply while waiting for the bus]

- java_xxx functions are exported from Java.inc, you can find it in the
template folder: http://,,,/java/Java.inc

- java_require is obsolete in new programs

- ajp is obsolete, unless you want to run JSP from apache

- ajp (through mod_proxy or mod_jk) must be configured correctly, see our
FAQ for details

Hi,

First of all i need to apologize since this email might be slightly
off-topic.
The only reason i am posting here is that it is a javabridge related.
Really i think though it is an apache2/tomcat integration issue.

So if this is unacceptable please let me know and (if possible) direct me
where i should go.

Here is the problem. I have a web application using the JavaBridgeTemplate.
The index.php is like so:
<?php echo "<br><hr><br>"; echo java("java.lang.System")->getProperties();
?>
It is deployed and i can execute in my browser at port 8080 (tomcat) and it
works.

The problem comes in when i try to go through apache2 via mod_jk.
The following is my setup (jk_mod is installed and loaded):

- /etc/apache2/conf.d/jk.conf:
workers.tomcat_home=/usr/local/tomcat
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/
worker.list=ajp13_worker
worker.ajp13_worker.port=8009
worker.ajp13_worker.host=localhost
worker.ajp13_worker.type=ajp13
worker.ajp13_worker.lbfactor=1

- /etc/libapache2-mod-jk/workers.properties:
workers.tomcat_home=/usr/local/tomcat
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/
worker.list=ajp13_worker
worker.ajp13_worker.port=8009
worker.ajp13_worker.host=localhost
worker.ajp13_worker.type=ajp13
worker.ajp13_worker.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=ajp13_worker

- last line in apache2:
JkMount /* ajp13_worker


So, again, from what i can tell it is not directly related to the javabridge
code but i am hoping from some words of wisdom from more experienced people
than i am.


thanks
matt

Hi,

the regression in version 5.5.1 has been fixed in CVS. It has been tagged as
Release-5-5-2:

http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/server/META-INF/java/Client.inc?r1=1.27&r2=1.28&view=patch

I am sorry for the inconvenience.


Regards,
Jost Boekemeier

Hi Andre,

the $version variable in common.inc.php (in web.sf.net/.../pjb/include/) now
points to the most recent version, which is 5.4.4.2.

Yes, I think so. Until sf.net gives us more control what is or is not
visible, we really have no other choice.

I have deleted the binary/5.5.2 and redhat/5.5.2 directories.

Hi Andre and others,

the new SF upload interface doesn`t support hidden releases anymore, does
it?


I have made a stupid mistake in the version 5.5.1 protocol parser. This has
been corrected in 5.5.2, I will check in the changed line tomorrow evening.

However, I think the 5.5.x branch needs some more time for internal tests.
Especially the RedHat and Debian versions, as both depend on a stable
upstream release.

Hi,

I think the xdebug C code is more a problem than anything else.

There's a pure PHP debugger ("gubed") which uses the official PHP-level API
(*token_get_all, ...) to attach the debugger to your PHP script.

The advantage of this method is that it is pure PHP code and therefore
cannot crash your PHP installation. And it will work with future versions of
PHP.

Well, you already have a working desktop application. Why don't you add a
standalone listener to call it from php?

Or, if you want to create a web application, create it using the
JavaBridgeTemplate.war add the necessary libraries to it, test it and then
call your tested application using a php front end?

Pretty sure since the code works when invoked from the command line.


But i just thought that i do import java.awt.geom.* which the itext call is
based on i believe. So do i need to java_require this library?

If so, how can i do that? Do i need to go look through the sun-java
installation to find the needed .jar file?

Hi,

i am trying to access a java library (itext.jar) from my java code (also in
a
.jar in the same directory as itext.jar).

The specific offending testcase-call to itext is:
PaperHeight = (int)(com.lowagie.text.PageSize.LETTER.getHeight());

In my java code i import from itext what i need and it works on the command
line (compile and execute). However, from the browser it does not.

In my index.php (which i use as a sandbox) i make the call:
java_require("../java/PatchAntenna_20090826/lib/PA.jar");
java_require("../java/PatchAntenna_20090826/lib/iText-2.1.7.jar");
before i create a new instance of my class which in turn calls the itext
method.

When i execute the php script in the browser i get:
Cause: java.lang.NoSuchMethodError: com.lowagie.text.Rectangle.getHeight()
which indicates to me that i cannot find the library.

What am i missing here? Did i forget something?

thanks for the help

Hi,

recent PHP versions still contain a bug in pfsockopen, which will cause a
short read when the tomcat back end is restarted or when tomcat closes an
open connection. The problem is an uninitialized variable in the php socket
layer.

If you receive the message "protocol error, length must be > 0 ..." when
using the Linux RPM, please add the following constant to the PHP script:

1.0E512

This illegal number will cause the PHP parser to reset, initializing the
socket layer as a side effect(!).

On all operating system except RedHat Enterprise and Fedora Linux the config
var JAVA_PERSISTENT_SERVLET_CONNECTIONS is off, so this php bug will not
cause problems there.

I will add the constant to the RedHat/Fedora RPM and work with the php
maintainers to fix this bug.

Regards,
Jost Boekemeier
