[Php-java-bridge-users] Hybrid JSP/PHP App

[Scott P. <sc...@go...>]

Fantastic package! Nice work everyone.

 

A question about building a hybrid application using both JSP and PHP.

 

It seems like the bridge supports all of these options:

 

1. Run Apache as the front-end. It runs PHP pages natively, and uses
connector

to run JSP's. Bridge can talk back to the Java end.

 

2. Run Tomcat as the front-end, and it serves both JSP's and PHP pages. This
seems amazing, but

the JavaBridge.war seems to be able to run PHP pages. But is it doing this
by

exec'ing the php interpreter, or actually calling back to Apache through the
bridge.

The example showing how to share JSP and PHP session seems to use this
model.

 

Is my analysis correct?

 

Now, considering option 1 (Apache front-end):

 

a. Can we share PHP and JSP sessions with this deployment? I'm unclear how
JSP

sessions are handled when using the Apache java connector.

 

b. Can my PHP page running in Apache actually talk through the bridge to a
webapp 

deployed on Tomcat? Basically I need to get to objects in the
ServletContext. I see

the j2ee example on how to connect to an EJB, but I'm not using any EJB's or
remote

objects.

Hi Scott,

Yes, of course. The "servlet engine behind a HTTP
server" is the only option available for an internet
server.

When the backend is running in a servlet engine or
application server, all pages are generated by the
servlet engine or application server. PHP is only used
to generate the content within the page.

For example if you set 

  java.servlet="/myctx/MyServlet" 

and you ask the server for a session handle via:

  $handle=java_get_session();

the server will generate an empty page with a random
cookie (with the path "/myctx") and ask php to
generate the content. The result will be returned to
the client.

The "php as a cgi sub-component" works similar.

The servlet context is there, but you cannot access it
at the moment (it is private).  Currently you can only
access the session store.

Why do you need to access the servlet context?

Accessing the implicit web objects (Was: Ant: [Php-java-bridge-users] Hybrid JSP/PHP App)

[Jost B. <jos...@ya...>]

Hi,

when java contains the appropriate hooks, it will be
possible to access the implicit web objects via


 java_context() (alias: "java_get_context()")

which returns a standard ScriptContext.

But this is for PHP/Java Bridge 3.0, which will appear
in a few years when java contains the necessary
classes.

I think this isn't important, in the meantime (for
version 2.0.9) I'll make the request object public.
You can access the servlet context from there.

Please see PR1323180 for details.


Regards,
Jost Boekemeier
