[Php-java-bridge-users] [Object types] Java Exceptions : how-to ?

[<php...@li...>]

Hello guys,

I have an EJB container, which is JBoss, and I access the EJB's via
this wonderful PHP / Java Bridge OS Project.

In my Java code I use exceptions all the time to detect errors, but
most importantly error types, and hence I have customized exceptions
(as everyone has) to detect what error happened. They also contain
text messages but I do not want to rely on this, since they can change
anytime.

Well the problem is that in ususal Java code I would check for errors this way :
----------------------------------------------------
try {
     loginUser(login, password);
}
catch (BadLoginException ble) { // ... }
catch (BadPasswordException bpe) { // ... }
----------------------------------------------------
And so I would determine what failed and choose what to do on this basis.

Apparently the only possible thing via the bridge is to use the
JavaException type :
----------------------------------------------------
try {
     $myremoteBean->loginUser($login, $password);
}
catch (JavaException $je) { // ... }
----------------------------------------------------

So how can I determine which error appeared, without checking the
error message (which is - I think - a bad practice) ?
I tried with the "java_instanceof" function but it seems that the
returned exception is just a "JavaException" object, and that the
invoked function's returned exception's type is lost.

Thanks for your help!!
