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

Hi,

I am sorry, but I could not reproduce these problems. The bridge works fine unless you try to mix different versions or even different libraries.

Which version of the bridge do you use? Are you sure that you use the PHP/Java Bridge or do you use something else?


Can you please post the results of the following calls:

jrunscript -classpath JavaBridge.jar -l php-interactive

> echo java("php.java.bridge.Util")->VERSION


Can you please deploy the standard JavaBridge.war and click on the jsr223.jsp and php+jsp.jsp examples?


Regards,
Jost Boekemeier

Dear all,

I am new to the PHP/Java bridge and trying to run the standard examples. I'm
trying to connect Java 1.6.0.6 with PHP 5.2.2 to call PHP from JAVA using
the scripting engine. The installation itself via the copy statement was
fine. I tried two options, in both cases the code compiles and seems to
connect to the PHP engine,but the results are not as hoped for:


// OPTION 1
javax.script.ScriptEngineManager manager = new
javax.script.ScriptEngineManager();
javax.script.ScriptEngine e = manager.getEngineByName("php-invocable");

e.eval("<?php class f {function a($p) {return java_values($p)+1;}}\n" +
"java_context()->setAttribute('f', java_closure(new f()), 100); ?>");
javax.script.Invocable i = (javax.script.Invocable)e;

Object f = e.getContext().getAttribute("f", 100);
System.out.println("Invoking");
String res = (String) i.invokeMethod(f, "a", new Object[] {new Integer(1)});
Sytem.out.println("Output: " + res);
e.eval ((java.io.Reader) null);

This leads to a null pointer exception after printing the line 'invoking'
when trying to call invokeMethod. That is, locating the 'f' function does
not lead to an object.


OPTION 2
System.out.println("Interactive engine");
javax.script.ScriptEngine e2 = (new
javax.script.ScriptEngineManager()).getEngineByName("php-interactive");
e2.eval("$v = 1+2");
System.out.println(e2.eval("echo $v"));
e2.eval((String)null);


This leads to a stack overflow exception:

        and etceteras

Any suggestions here on what I'm doing wrong?

Thanks already for any suggestions you can provide!

Kind regards,
