Re: [Php-java-bridge-users] Problems w/ java_context() under Tomcat 5.5

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

Hi,

> Am I doing something wrong when calling the

java_context() returns the current Java context. It is
a JSR223 context if JSR223 is available. A servlet
context, from which the servlet request, response, ...
can be obtained, if PHP is running within a J2EE
environment. Or a remote context when Java is accessed
through a Apache or IIS front end or from a PHP
command line binary:

<?php

require_once
   ("http://localhost:8080/JavaBridge/java/Java.inc");

$ctx = java_context();
$res = $ctx->getHttpServletResponse();
?>

In the above example $res is always null, unless the
initial request came in through the tomcat port 8080. 

What do you want to do with the ServletRequest and
ServletResponse objects anyway? When PHP is invoked
from the command line or running within Apache/IIS,
there's no servlet involved which could hold resonable
values for the HTTP "GET/PUT/POST" method or URL
parameters.

Yes. RemoteContext always returns null for
getHttpServletResponse etc. See
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/servlet/RemoteContext.java?revision=1.1&view=markup

This will not work either. The JSR223 functionality is
only available if the bridge is running in a JSR223
environment:

ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine e = m.getEngineByName("php-invocable");
e.eval("<?php function f($p) {return 'hi '.$p;}?>");
Invocable i = (Invocable)e;
Object o = i.invokeFunction("f", new
Object[]{"Java"});
System.out.println(o);

=> hi Java



Can you please explain what you want to do?
