Java error ClassCastException

Hello there,

what is wrong with this code. I get this error even though I cast it to Long or am I doing something wrong

java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long

Users users = new Users();
users.setId((Long)dsRequest.getFieldValue("id"));

Open in new window

cheers

Hi CEHJ,
here you go

Looks pretty straightforward to me - getFieldValue() returns a String which you are trying to cast to Long, which can't happen.

CEHJ

MIght be just me but i don't see a method of that name anywhere

i agree with cehj

getfieldvalue method not found in dsrequest class
