XI Java Mapping

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
