Hi Andre,

thank you very much.


> .. PhpScriptContextFactory.java file allowed

Yeah. It should have been PhpServletContextFactory... :) All Servlet*.class files are now stored in the php-servlet.jar to avoid class loading issues when the php-script.jar is loaded from the jre/lib/ext directory, but the php-servlet.jar is not.


I have fixed the deprecated warning. The servlet implements an interface which exports three deprecated methods. A class which implements such an interface must add a deprecated tag, otherwise one will see the deprecation warnings.

I have tagged the release as:

 RELEASE-5-3-2-1
 ROOT_RELEASE-5-3-2-1


Again, thank you very much for compiling the debian packages!

Hello,
Bringing back the PhpScriptContextFactory.java file allowed the
compilation.

Hello, Jost
Many thanks for your answer.

Only the java/Java.inc is neccessary.

Everything except WEB-INF/web.xml, WEB-INF/lib/{JavaBridge*,*php*}.jar

If you want to run PHP scripts directly from servlets, you need to keep the WEB-INF/cgi directory.

I would use mod_proxy instead of mod_jk. mod_proxy also supports load balancing, if you need it. Please see our FAQ for details.

Yes. If you touch the WEB-INF/web.xml, the web context automatically
reloads all libraries.

You can copy JavaBridge to MyWebApp and access that. Both applications will be separated. If you want to hard-code all requests to MyWebApp, just fetch the Java.inc from MyWebApp or hard-code the string in java/Java.inc or use a define(...) before including Java.inc. 

Please see our FAQ for details

Hi Andre,

sorry about that. I forgot to "cvs remove" these files:

  * server/php/java/script/EngineFactory.java,server/php/java/script/InvocablePhpServletContextFactory.java,server/php/java/script/InvocablePhpServletLocalScriptEngine.java,server/php/java/script/InvocablePhpServletScriptEngine.java,server/php/java/script/PhpServletContextFactory.java,server/php/java/script/PhpServletLocalScriptEngine.java,server/php/java/script/PhpServletScriptEngine.java,server/php/java/script/PhpSimpleHttpScriptContext.java,server/php/java/script/ScriptFileReader.java: Removed    

the reason for the change is in the ChangeLog:
http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/ChangeLog?revision=1.189&view=markup

Can you please remove them from the CVS?


The bridge uses certain API's which are deprecated since Java 6. But removing them is not possible at the moment because it would break backward compatibility with Java 1.4.

But I will have a look at this issue this evening.

Hello,
I am trying to generate the debian packages and found that

Well, for trying to go ahead, I removed that java entry and

Hi ,

thanks for developing this bridge. I;m new here and want to use this to call
Java from PHP and vice versa.

I have deployed Java Bridge on Tomcat and copied the same on Apache. Also
able to access numberguess php from Apache WebServer. It means I am able to
configure it well.

Now my concern is.

1) What all things I can remove from JavaBridge directory on Apache as I
dont want to put un-required stuff on Apache WebServer.
 --- I have tried removing everything except "java" directory from
JavaBridge directory and still it worked. Is it okie to just keep "java"
directory on Apache WebServer.

2) What all things I can remove from JavaBridge directory on Tomcat? As it
contains samples which wont be useful for my application.

3) Do I need to setup mod_jk between Apache WebServer and Tomcat , or bridge
will take care of communication by itself.

4) When I develope my Java Classes where I need to put jar file?
   is it JavaBridge/WEB-INF/lib? , will it automatically put in classpath?
or do I need to do any specific configuration?

5) Can I also develop seperate WebApplication and deploy on Tomcat and still
can access from PHP in Apache WebServer?


    thanks in advance.

have a nice day,

Hi,

> Do I have to keep tomcat running as well? 

without a running java VM a java extension would not make any sense, I think.

Hi,
 Thanks for the quick response.

> 1. Copy JavaBridge.war to tomcat's autodeploy folder
> 2. Copy the created webapps/JavaBridge directory over to the IIS/Apache doc root
This might be a very stupid question but Do I have to keep tomcat
running as well? Or just copying it in doc root of apache is
sufficient?

Thanks

Hi,


> - Which is the suggested way of deploying php-java bridge?

1. Copy JavaBridge.war to tomcat's autodeploy folder
2. Copy the created webapps/JavaBridge directory over to the IIS/Apache doc root

The java.so or php_java.dll start a Java process in minit and destroy it in mshutdown. minit/mshutdown are called when IIS or Apache starts/stops. Or when the CGI or CLI binary is invoked/terminated, which happens for every request.

Java threads from a thread pool show up as processes in old Linux kernels or psutils.

Hi,

thanks for all the advise. I tried your solution of copying php-cgi.exe and
php5ts.dll to my local working directory. That indeed
solved the issue of the Stackoverflow I got on the command prompt with the
interactive php engine.

I am attempting now to resolve the problems I described using the bridge
from Netbeans. I'll keep you posted on the outcome, though
it may take some time (sometime next week likely) before I can get back to
you.

Thanks already!
Bart

Hi,

 We have a php web application which will be accessing a third party
Java API (in form of jars) what is the suggested deployment method? I
have tried following:

1. Compiled the source which results in java.so and then include it in
php.ini using 'extension=java.so'

2. Start the servlet engine explicitly using java commend 'java -jar
JavaBridge.jar SERVLET:8080 3 javabridge_servlet.log' inside
JAVA.STANDALONE folder.

 I have couple of questions.
- Which is the suggested way of deploying php-java bridge?
- The servlet engine which is part of the JavaBridge.jar is it stable
enough for production?
- Good thing about option 1 is that I do not have to start any
separate process it gets started with apache but we have experienced
that for some reason for every call it was creating a separate process
and we end up having lots of java processes. Are we using it
incorrectly?

Thanks for the help.

Regards,
Amit.
