[Php-java-bridge-users] calling methods with String parameters

[<art...@ug...>]

Hello,

I'm using version 3.0.2 with PHP 5.0.4. I don't know why i'm getting this
strange error:

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed:
[o(Indexador)]->index((String)o(String), (String)o(String)). Cause:
java.lang.NullPointerException"] thrown in h:\wamp\www\testjava.php on
line 9

with this piece of code:

<?php

java_require("h:/search_engine/lucene-1.4.3.jar;h:/search_engine/Indexador.jar");
$indexer = new Java("org.ew.lucene.Indexador");
$indexer->index("h:\puleva2\puleva2\data","h:\search_engine\index");

?>

the index method is defined as follows:

public void index(String DataDir, String IndexDir) throws Exception {

}

Any help is appreciated.

Regards,

Arturo.

Answering myself,

The problem seems to happens with the second parameter of the index
method, that contains a character '_'. This cause null exception! is it a
bug? Changing that directory to something else like 'h:\test' solve the
problem.

Cheers,

Arturo.

I thought it was solved (caused it ran changing that dir!), but
strangely not... going to try debugging the code of the index method,
but it seems unstable. I can't find the logfile! I'm on Windows XP.

Cheers,

Arturo.

Hi,

> java.lang.NullPointerException"] thrown in
> h:\wamp\www\testjava.php on
> line 9
> public void index(String DataDir, String IndexDir)
> throws Exception {

is it possible print the stack trace? Please see this
(http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/tests.php5/printStackTrace.php?rev=1.5&view=markup)
as an example how to print a stack trace.

If the null pointer appears in the PHP/Java Bridge
code, please open  a ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)

BTW: Catching exceptions using try/catch is a good
idea anyway, especially if your java code reports
these exceptions to php level.
