The field is declared as Booelean. How can we check if we have null in this field.

Is this a servlet question or a general java one? If it is general java, you should post it in the appropriate forum. If it has something to do with servlets, I am having trouble understanding your question. What field? An attribute? A parameter? Please be more specific so we can help.

If it is Boolean, the Object wrapper for the boolean type, then you can test for null the same way you test any other Java object for null as a previous poster already pointed out.

If it is boolean, then it is a primitive type that can contain only the values True or False. It cannot be null.
