XI Java Mapping

[Former Member]

HI Experts,

I have this problem with my UDF. I want to check if a field exists or not. I don't know the right Java syntax for it.

I use

if (ObjectA<i>.equals(""))

{

result.addValue(e<i>);

}

I can't use (objectA.length() >= 0) because I'm using the Queue function that doesn't allow ().

Could anyone help please?

Thanks

objectA.length == 0

Hi, Thanks for the answer but it still doesn't work.

I have the right input in the source but it still doesn't prdouce anything.

The field is existing but it appears as if it is not there.

If (ObjectA.length == 0)

{

result.addValue(e<i>);

}

If you want to check for existence, do it that way:

objectA.length > 0

Hi Yes it works now with >0.

Thanks.

but now occurs another error when several segments comes in the source and the last one has the criterias as I explained before. I get this error: Exception:[java.lang.ArrayIndexOutOfBoundsException: Array index out of range

before you use

result.addValue(e[k]);

you have to check, whether the array has values,

you can do:

if (e.length > k)
  result.addValue(e[k]);

Hi,

the strange part is that ObjectA.length > 1 works but I get the same result when ObjectA doesn't exist. which is not how it should be. It seems that it doesn't care about that condition.

Do you know why?

Thanks

Is your UDF of type "values of a context"?

Otherwise it won't work.
