Re: [Php-java-bridge-users] Help

BTW: Which PHP version and which OS do you use? While testing the above code
against the latest PHP 5.3.1, it appears that PHP 5.3.1 on Windows discards
all error messages(!).

Please use a stable PHP version instead (PHP 5.2.x).

Your code is correct. Except for $rs->hasNext(), which returns a Boolean
object. Your loop

  while($rs->hasNext())

never returns. Use an explicit boolean cast:

  while((boolean)(string)$rs->hasNext());

or

  while(java_is_true($rs->hasNext());

I think the reason why your query fails is that ModelD2RQ cannot parse an
UTF-8 file. But that's a d2rq issue, I think.
