Error in setting node value

Dear all,
I'm trying to create an xml and i'm facing an error whike trying to set an node value using the code ,element.setTextContext.

The error that i'm getting while trying to compile is "The method setTextContent(String) is undefined for the type Element".The quick fix solution of casting doesn't help solve the issue.

What is more interesting is, when i create a new project in the same IDE instance, the same code works fine. Hence i am guessing the problem must be with the Jars or the class path variables. Since i'm new to this programming language and this being my first week, i'd greatly appreciate any help. I have pasted the code below for those who need to take a look. Also the IDE i'm using is RAD 7.5 and the compiler version is 1.4( changing it to 1.5 helps in solving the error, however i'm hard pressed to use 1.4 for project purposes, also the new project runs fine under 1.4 anyways).

Code Java:

Please copy and paste the exact error message you get when you compile the code. I get a different error message when I compile it. It's important that you post the exact error message. Copy and paste it, don't type it in.
