Re: [Php-java-bridge-users] Isolation of WebApps under Tomcat

[<php...@li...>]

Hi,

first of all thank you very much for the bug report.

We could reproduce the problem that, when the PHP/Java
Bridge is installed in the shared directory, as
described in our FAQ, all classes are loaded via the
same webapp classloader.

We currently don't have a workaround for this tomcat
problem. 

However, this isn't a bug in the PHP/Java Bridge code,
so we won't fix this problem, even though it is
serious.

Yes. When the JavaBridge.jar and php-servlet.jar are
loaded from the shared web folder, tomcat loads all
classes from the same web classloader. This is almost
certainly a tomcat bug.

It should occur in all Tomcat versions < 6.

JSP is different. It compiles Java source files to
Java byte code and then invokes the byte code from a
separate classloader. The PHP/Java Bridge could do the
same to work around the above problem.

In the meantime please do not copy the JavaBridge.jar
and php-servlet.jar into the shared tomcat directory.
