Strange Question

[Balogh Andras]

Hi,           I have a strange question. How hard is to the server to handle Exceptions ? To be more precise here is an example: I have a form with 3 fields:name,telephone,address. I retrieve the parameters in the servlet with the usually method req.getParameterValues("name")[0]. Now if the servlet is called from the right form that everything is OK. But if someone removes the 'name' field from the form my servlet throws a NullPointerException wich is a normal behavior. So my question is: this exception will be a SHOCK to the server(or the JVM) or it will terminate the servlet as nothing were happen? Or another question: Too many exceptions will produce an  abnormal behavior  of the server(JVM) after a time ?? I am asking this question becuase if the answer is NO (meening that Exceptions don't affect at all the server or JVM) that i will drop the extra if conditions like: if(req.getParameterValues("name")!=null) name=req.getParameterValues("name")[0].     Waiting for Your answers.   Thank you,                 Andras
