Error handling - Help required !!

[Rajat Gupta]

Hi Support !

I am using rhino.
How i can do error handing using rhino ?

Question example -
I had some method which is having some n number of input params, if one required param is undefine then i want to throw an error. For this I made a JS scriptable error object.
so how i can set this error object by using rhino error object ( if it does have) ?

please explain in detail.
I would be very thankful to you.

Thanks.
Rajat

Hi friends !

Here is the code.

try{
alert(); // one argument is required for alert
}catch(e){
console.println( "e = " + e)
console.println( "e.name = " + e.name)
}

or just call

alert(); // one argument is required for alert

can we get the e object ?
what is the type of e object ?

Thanks
Rajat

maybe, you can create error objects, by using throw(), but I don't
think using exceptions is a good way of flow control.
(but that's just me).

Actually I had a java object corresponding to each JS object.
for example: X500Name java object and corresponding JS x500Name object.

So I need the coressponding java object corresponding to JS e Object in following js script.

try{
alert(); // one argument is required for alert
}catch(e){
console.println( "e = " + e)
console.println( "e.name = " + e.name)
}

Hope you got answer of your question.
Please provide more detailed answer.

Thanks
Rajat

What does that mean? You printed the e object, didn't you?

JS objects don't really have a type in the was Java objects do. Again, what
is your goal?
