Re: [Php-java-bridge-users] Getting back null-object from new Java(...) - how to debug this?

From: <php...@li...> - 2007-05-03 22:28:45

Continuing to investigate on this new Java('...') call that returns a null
I pushed the log-level even higher and I am now getting this log from the
PHP/Java bridge:

-------------------------------------------------
The "NCI-ctor()" line (about 20th from bottom) comes from the constructor,
which reads:
...
public NCI() {
System.out.println("NCI-ctor()");
}
...
and since it's the only thing the constructor does, I would assume that it
also completes.
That means, it is the returning of the object that must fail, or how could
I otherwise get a null back from the constructor?
But the line
...
Result [Object 2059172540 - Class:
demo.NCI:ID1344884777:LOADER-ID1560567044]
...
(seventh line from the bottom) suggests that there actually IS some object
returned, so why does the PHP-code then obtain a null???
Really puzzled!
