In my java application I have an object declared as Extrair extrair = new Extrair(); And I use this object and its attributes for my servlet. But I need to pass this object to .jsp. In the jsp I use extrair = request.getAttribute(); , only the request method returns an Object and I'm assigning an Object to an Extract.

How can I resolve this?

java jsp

It indicates that you simply need to cast (as @mgibsonbr has indicated), however, to ensure that a ClassCastException is to verify that the object instance matches the class you are using:

Object attribute=request.getAttribute();
if(attribute instanceOf Extrair)
    extrair = attribute;
