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

Hi everybody.

We are trying to access a Java class (standalone app) inside a PHP page.
This PHP page runs under a HTTPS secure section.

We followed the instructions on 
http://php-java-bridge.sourceforge.net/pjb/standalone.php
Also we set the properties allow_url_fopen and allow_url_include to "On"
We tried:
     require_once("http://localhost:8085/JavaBridge/java/Java.inc");
     require_once("https://localhost:8085/JavaBridge/java/Java.inc");
     define("JAVA_HOSTS", "127.0.0.1:8085");

But nothing worked.
Is there any more configuration needed? Maybe some related to SSL on 
PHP...

Please some help on that. 

We would like also to avoid the use of URL on the requice_once call. Is 
that possible to refer the Java.inc inside the Jar file? Or there is 
another way?

Thank you.

Hi,

The example JavaBridge.war from the php-java-bridge_documentation.zip
download contains the OSGI framework. It uses separate classloaders,
similar to our deprecated java_require() feature, to allow loading
different library versions at a time. But since it has the same
issues, I cannot recomment it either. For example we ran into several
class-loading issues while preparing the BIRT report example.

Yes. Tomcat separates all web applications using different class
loaders. You may run into PermGenSpace OutOfMemoryErrors and some
libraries should not be loaded this way; see
http://tomcat.apache.org/tomcat-5.5-doc/RELEASE-NOTES.txt section "Web
application reloading and static fields in shared libraries". But if
you don't load too many libraries and if the library authors have
payed attention [1], this will work.

Hi Jost,

Thanks a lot for your info on my question. I understand about the lack of
module system in java.

In my case we have many php applications on one server using different
versions of Jasper Reports Libraries. So if I put all the versions of
libraries in one WEB-INF/lib/ folder then I believe it would cause issues on
loading correct libraries. In this case can I have two JavaBridge
applications running in my Tomcat server so that the libraries are not
messed up? If that is fine then could you please tell me how I can make two
instance of the same application? If it's simply deploying the application
twice then that's easy but if I need to change any settings to make it work
I am not sure how can I do that.

Please help.

Thanks a lot.

Best regards,
Hameed
