Hi -
OK, I suspect this may be a bit off the beaten track, but thought I
would ask anywise...
I have set up a Tomcat server with the php-java-bridge servlets and
support, tested and the examples all work fine, so I know the basic
environment works....
Now I have a webapp, and it has a .jsp file that mostly contains
javascript code, along with some jsp variables and of course some html
code. Within one of the javascript sections I want to use a php script,
and I am going to want to do some string substitutions from some of the
jsp variables. That need seems to prevent me from incorporating the php
script in a separate file. So the outline of the file is something like
this -
----------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<%@ page import="java.io.*" %>
<%@ page import="org.apache.commons.lang.*" %>
<head>
<%
// JSP code here, for example -
String url = request.getAttribute("URL").toString();
%>
<script type="text/javascript">
// javascript code here...
if (config.Manager) {
with (config.Manager)
{
<?php require_once("java/Java.inc");
// <?php require_once("http://localhost:8086/mywebapp/java/Java.inc");
$IMConfig = array();
$IMConfig['images_dir'] = '<%= url%>/images';
// more php script here
?>
}
}
</script>
</head>
<body>
// html, javascript, jsp stuff here....
</body>
</html>
-------------
I have been fooling around with this, but so far it does not appear that
I am getting the php script to execute. Can some kind soul help lead
me to a solution? Thanks in advance...
Marc...

Hi,
please take a look at the jsr223.jsp from the documentation download.
> <?php require_once("java/Java.inc");
It's a JSP, so you need to use JSP syntax:
<%@page import="javax.script.*" %>
<%@page import="php.java.script.servlet.PhpCompiledHttpScriptContext" %>
<%!
private static final CompiledScript script;
static {
try {
script =((Compilable)(new
ScriptEngineManager().getEngineByName("php"))).compile(
"<?php echo eval(java_context()->get('script')); ?>");
} catch (ScriptException e) {
throw new RuntimeException("bleh!");
}
}
private static final String evalPHP(String arg) {
CompiledScript instance =
(CompiledScript)((java.security.cert.CertStoreParameters)script).clone();
instance.getEngine().put("script", arg);
OutputStream out = new ByteArrayOutputStream();
Writer writer = new OutputStreamWriter(out);
instance.getEngine.getContext().setWriter(writer);
instance.eval();
writer.close();
return out.toString();
}
%>
<script type="text/javascript">
var = <%= evalPHP("hello world"); %>

Hi again, insert a instance.getEngine().setContext(new PhpCompiledHttpScriptContext(instance.getEngine().getContext(),this,application,request,response)); before calling instance.eval(). Otherwise JSR223 will use the default context, which isn't very usable in a web-context. Regards, Jost Bökemeier |

Hi Jost - Hmmmm since the method evalPHP, as you sent it to me in your
previous email, is declared private static final, one cannot use the
'this' parameter. Do you see any problem with removing the static final
from the declaration? That allows this to be called in the context of
the instance of the servlet that is running. But doing so will then
cause the parameters of evalPHP - application, request, and response to
be undefined since this code is within the Declaration section of the
servlet. I think the application parameter can be retrieved via a call
to this.getServletContext(), but the only way to get the request and
response parameters will be to pass them in to the evalPHP method. Do
you concur? I am thinking the following -
private String evalPHP(String arg, HttpServletRequest request,
HttpServletResponse response) {
CompiledScript instance =
(CompiledScript)((java.security.cert.CertStoreParameters)script).clone();
instance.getEngine().put("script", arg);
OutputStream out = new ByteArrayOutputStream();
Writer writer = new OutputStreamWriter(out);
instance.getEngine().getContext().setWriter(writer);
instance.getEngine().setContext((ScriptContext)new
PhpCompiledHttpScriptContext(instance.getEngine().getContext(),this,this.getServletContext(),request,response));
try {
instance.eval();
} catch (ScriptException e) {
throw new RuntimeException("bleh!");
}
try {
writer.close();
} catch (IOException e) {
throw new RuntimeException("bleh!");
}
String result = out.toString();
return result;
}
I have gone ahead and tried this, and it almost got me to what I want.
But one problem remains and I don't grok the code enough to be able to
solve on my own, so need a bit more guidance. The PHP script that I want
to embed in the middle of a Javascript section generates a line of
Javascript that I want the servlet to write back out, at the point where
the call to evalPHP is made. But when I execute this jsp servlet, the
generated Javascript from the PHP script is being put out at the very
beginning of the document. (I was also surprised that the return result
from evalPHP is null....)
Thanks again for all your help! Marc...

I am sorry but I don't follow you... What should be a method? My PHP
script? If that is what you are referring to, then how will that affect
the placement of the output from the script when it is evaluated? And
how do I call it? Perhaps I need a better example to help me grok this?
Keep in mind that what I am trying to accomplish is to executed an
embedded multi-line PHP script inside a Javascript segment, all of which
is inside a .jsp file..... At the moment the PHP script is being
executed, but the output, being done via echo statements in the script
(and called PHP functions) is all being placed at the beginning of the
output document, not at the place where the evalPHP call is made...
Also, are the changes I made to the evalPHP function correct? I presume
that the first argument of evalPHP (String arg....) is the string that
contains the actual script that I want to execute. I have concatenated
all the PHP script lines into a single String variable and this is what
I pass to evalPHP.
Thanks again for all your time and help! Marc...

Thanks Jost for pointing me in the right direction! One immediate
question comes up however, where do I find
php.java.script.servlet.PhpCompiledHttpScriptContext? It is not in any
of the jar files that I picked up....

Jost, all -
I have been doing more investigations into why the php-java bridge is
not working as I would expect, but so far I got no joy in why it is
failing... So I thought I would send in a concise version of the jsp
code/file I am trying to set up, and see if you or anyone else can spot
what I am doing wrong.... (this also shows the interplay between jsp
variables and the Javascript/PHP scripts, which is why I am choosing to
use JSP)
What I am discovering, is that as expected the method evalPHP is being
called (twice). The call to the function - outputJavaScript in my PHP
script does indeed return a Javascript statement (via the internal call
to pass_to_php_backend), which is a String variable, and I can in fact
put an echo statement just before the return and see that the expected
Javascript statement is produced. But what is NOT happening is that
this returned string is produced in the output document, at the point of
call to evalPHP. (I have placed calls to alerts to show this is indeed
what is happening, as can be seen in the following code.)
Thoughts? Thanks again in advance for helping me with this... Marc...

The PHP/Java Bridge code is correct. The decorator you've set connects
the writer, reader, errorWriter to the servlet. So your code has no
effect.
Please see the example code I've given.
BTW: For PHP/Java Bridge 6.2.1 I will rename the decorator to
"PhpHttpScriptContext". Please either use your own decorator (copy
PhpHttpCompiledScriptContext.java to your project) or please use the
new name.
The test script I've used is below:
