Hi, > Does this sounds familiar to you or anyone? not really. But I assume that there's a problem with the servlet => ContextRunner context switch. This might be a simple setup problem. We will add a HOWTO to the PHP/Java Bridge 4.1.4 download which describes how to setup the bridge in a cluster environment: http://sourceforge.net/tracker/index.php?func=detail&atid=679233&aid=1740947&group_id=117793 Thank you very much for the bug report!

Hi Jim, > have to > completely restart Apache before it'll find any new PHP doesn't keep any state, so you don't need to restart apache. The cache, if any, is in the back end. > methods? Is this the > same for running the Java side in it's own VM via > tomcat? Well, it is a URLClassLoader problem, which caches the loaded classes using an associated cache in the sun JVM. It'd be interesting if the GNU VM has the same problem. There are certainly ways to workaround this, but how much sense does it make to pull java libraries from a http:// URL during development, anyway? Due to the caching in the URLClassLoader's associated VM cache you'll need to restart the VM to see the new code. Why don't you simply use load local jar files instead?

Hi,
the following code may show the problem. It is written in PHP, but it could have been written in Java as well, as it demonstrates a problem with Java's URLClassLoader:
xtest.java:
public class xtest { public static String f() { return "12"; } }
xtest.php:
<?php
// The following code shows a bug in Java's URLClassLoader
// While running this script, modify xtest.jar, so that f() returns
// "123" instead of "12".
// You will see that the jar file is fetched (its size changes)
// but the URLClassLoader discards it and uses the cached
// jar file from the previous request.
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
while(true) {
$url = new java("java.net.URL", "http://localhost/xtest.jar");
$conn = $url->openConnection();
echo $conn->getContentLength(); echo "->";
$conn->disconnect();
$loader = java("java.net.URLClassLoader")->newInstance(array($url));
$clazz = $loader->loadClass("xtest");
echo $clazz->f(); echo "<br>\n";
sleep(1);
}
?>

Apache Tomcat/5.5.17 - Error reportFatal error: php_mod_java(88): Protocol violation at pos 155 while trying to connect to 127.0.0.1:80(/JavaBridge/test.phpjavabridge).
Did you start the nodes with -Dphp.java.bridge.promiscuous=true?
Without it the bridge will not be able to connect to the context runner's on the nodes.
In theory one can switch off the ContextRunner's and use a HTTP tunnel by setting an option in the web-inf/web.xml. If the C implementation doesn't receive a redirect from the servlet, it will continue to send all protocol requests via HTTP PUT using a session variable. But this will be very slow.

Thanks Jost for your email.
I guess we have not set up our cluster correclty for the =

those work correctly in the cluster. But the one that uses the =

not seem to be working. I finally have been able to get an exception:

Well, even in other examples where I have everything spelled correctly, I still get this problem. It seems that I have to completely restart Apache before it'll find any new Java methods but even then, it doesn't find certain methods in my Java classes. Is this always true though, where I have to restart Apache to allow the php-java-bridge to find any newly added Java methods? Is this the same for running the Java side in it's own VM via tomcat?

Just tried it -- works great! All the log4j logging from jboss works fine - the configuration is no longer reset. I don't have chainsaw setup on 445 (I only use log4j to log to files and the console), but log4j is on my global classpath for jboss.

Hi, [bridge class loader uses cached classes even though a jar file fetched from a remote URL has been changed] I think Martin's DynamicJavaBridgeClassLoader cannot check the modification time for remote jar files.

Hi, I assume your setup is like this: http://www.onjava.com/pub/a/onjava/2004/03/31/clustering.html If I understand this correctly, the management node must detect the failure of one of the cluster nodes and switch it off. I haven't tested the bridge in a cluster environment (we should do this, though); the bridge is a standard web application so that the operation mode of the J2EE environment should be completely transparent. Which cluster algorithm do you use? Do you use sessions? How do you store the sessions? Regards, Jost Boekemeier __________________________________________________ Do You Yahoo!? Sie sind Spam leid?

Hi, =20 There is something you could possibly help us with. We have a cluster = with two machines that have (tomcat 5.5.17), jdk1.5.0_06 and php 5.1.2 = each. Our web application uses php-java-bridge. We have noticed a weird = behavior though. When both instances of tomcat are running within 15 to = 30 min one of the tomcat instances stops responding and a browser window = where we are accessing our php application blacks out. Has anyone = experience a similar problem? We have not found exception in the log = files, so we have no clue what could be going on. Please let me know if = you need me to provide more information to help me find out what could = be causing the failure in the tomcat cluster. =20 Thank you very much in advance. |

This has been fixed in version 4.1.2. Please use this version instead. The bridge contains a php.exe and a php.ini file in the WEB-INF/cgi directory. In previous versions the system php executable used to read the local php.ini, even though the option prefer_system_php_exec is set to On in the web-inf/web.xml. As a immediate workaround please delete the php.ini from the WEB-INF/web.xml directory.

Hello,
I have to connect an existing PHP web-application with a new JSP-Part =
but fail to get the MySQL connection within the existing PHP application =
when I use the PHP-Java-Bridge.
The development is under WinXP, the production environment is linux.
a.. php-java-bridge-4.1.0a=20
b.. apache 2.0.55=20
c.. tomcat 5.5.2=20
d.. MySQL 5.0.18=20
The installation of JavaBridge as described by ACET was no problem.
a.. downloading the war file=20
b.. unpacking the war file to get JavaBridge.jar and php-servlet.jar=20
c.. copying the JavaBridge.jar and php-servlet.jar, located under =
WEB-INF/lib to $CATALINA_HOME/shared/lib=20
d.. copying JavaBridge.war to $CATALINA_HOME/webapps and startup =
Tomcat
Then http://localhost:8080/JavaBridge/ showed me the samples to execute. =
Everything works so far, even the former PHP-application can be called =
by localhost:8080/... =20
Except that that the php-info example and the existing PHP web =
application which heavily depend on using MySQL are signaling that the =
MySQL extention is not included in the compilation and therefore no =
MySQL statements are processed.
I thought an new line like
extension=3Dphp_mysql.dll (and something similar for the =
linux counterpart)
in=20
$CATALINA_HOME/webapps/myapp/WEB-INF/cgi/php.ini
would do the job but that try did not change anything.
How can I use the formerly loaded extentions like MySQL with =
PHP-Java-Bridge?
Thanks in advance
Joachim

Hello list, Firstly, thank you to the php-java-bridge developers - this project has proven invaluable to me and has worked out of the box with little configuration. I recently have installed the JavaBridge.war into a JBoss/Tomcat configuration. JBoss uses log4j for all of its logging, and all of the other components for our web application thus use it as well. It looks like the JavaBridge.war resets the log4j configuration, when it finds log4j.jar on the class path and attempts to setup the ChainsawLogger. When this happens, all logging for any component in JBoss is disabled, and no more logging output occurs throughout my app server. A reference to how someone else got around this issue in the past: http://sourceforge.net/mailarchive/message.php?msg_id=20061014163030.20262.qmail%40web27908.mail.ukl.yahoo.com I've already modified the Java source files to just use the FileLogger class rather than reconfigure log4j (and thus lose the rest of my jboss logging). However, I am running into issues on the build process. I am a Java developer unfamiliar with autoconf/automake -- can someone point me at the steps necessary to recreate the JavaBridge.war file? I'd like to only modify the source for the 4.08a version I am using (or whatever the latest stable release is), right now I checked out the latest from CVS, but I'd rather not deploy it until the next stable release. Any thoughts on making the logging more configurable - or just changing the default detection scheme for log4j to make it not reset the entire logging configuration? Thanks for your help, -Mark |

Hello, I used an older version of the bridge with php_java.dll under windows. Now I have to use php5.2 and the latest release of the bridge doesn't have php_java.dll... As I read in the mailing list, I have to recompile the bridge extension, but I don't how how. Where are the sources ? is it possible to compile with mingw under windows ? Regards, Benjamin Fourticq |

Hi, > I could not reproduce this okay, I could reproduce this now. We actually have a feature test which checks if the current thread context class loader is out of sync with the java bridge class loader. But this problem happens only when persistent connections are used, not with a named pipe communication channel.

Hi Jonathan, I could not reproduce this, but I think I see the problem: The classloaded referenced by the current thread context is out of sync with the classloader kept by the bridge. This may happen when persistent connections are used, but the bridge does not call recycle() at the end of the script. This happens when the pure PHP implementation is used, which uses a different path than the C implementation. As a workaround please modify your Java.inc and change the "pfsockopen" to "fsockopen" (all occurences). However, this problem should be fixed in version 4.1.1. (The current test version is 4.1.0b, please use the link http://sourceforge.net/project/downloading.php?group_id=117793&use_mirror=osdn&filename=php-java-bridge_4.1.0_j2ee.zip&15111070). > command line.
